CHAPTER – 1
HISTORY OF WATER UTILISATION IN CHAMBAL BASIN
The river Kalisindh, which forms part of lower Chambal sub basin which ultimately is a part of Yamuna sub basin, is the biggest tributary of river Chambal. It holds around 35% of the catchment area of
river Chambal lying in the state of M.P. The river Kalisindh is joined by another major tributary river Newaj, before it finally meets river Chambal. Till the end of 18th century almost all of the water available in the basin was simply flowing down in to Yamuna river to finally
join the river Ganga. It is in the start of the 19th century, when some sincere efforts to harness this
water wealth was started and completed in Chambal basin falling under sub zone I which now form
the State of the M. P. Even almost all these efforts for harnessing the water wealth of Chambal were
concentrated in the upper Chambal zone only and during the late fifties a series of multipurpose dam
were constructed on river Chambal itself. These constitute Gandhi Sagar dam, Rana Pratap Sagar
dam, Jawahar Sagar dam and the Kota barrage. Apart from this a number of minor and medium tank
schemes and lift irrigation schemes were also taken up in the last two decades of the 20 th
century.
Some of the important names under these schemes are Khankhedi lift irrigation schemes,
choma,Chambaleshwar,Indergarh, Chaldu etc. However not much of the work was taken up in the
case of lower Chambal sub basin i.e. in Zone-II accept construction of 4 medium schemes on the tributaries of river Kalisindh namely Tillar,Chillar,Lakhundar and Piplia kumar, apart from
construction of some minor irrigation schemes and small lift irrigation schemes.
Even no sizable project was taken up in this sub basin for water supply schemes except the
construction of small anicuts and pickup weir by municipal bodies despite acute drinking water
shortage in this region of Malwa.
MOHANPURA DAM PROJECT
A view of river in month of September
A major project namely Ranjit Sagar dam near Shajapur town on main river Kalisindh is in the stage
of investigation and consideration since from last 25-30 years, but still the project proposals could not
materialized for one other reason. Similarly three other medium projects in the upper Chambal basin, namely
Maxi nallah, Ankiya and Lodhari etc also could not be taken up so far for actual construction purposes due
to various reasons. The ultimate sufferer is the upper Chambal basin area in terms of meeting out its
irrigation, domestic, industrial and other needs due to non construction of any major dam /reservoir on the
river. The situation is so critical that almost in every alternate year even the drinking water supply after
march is to be planned once in three days or once in a week from most of the town situated in the Kalisindh
sub basin.
The concept of Mohanpura dam and reservoir has come up as a addition to earlier submitted
Kalisindh - Chambal link canal project and as a part of Kalisindh river basin complex which will be having
three major components of RS dam, Mohanpura dam, and PKC link canal project. Even otherwise if the
concept of PKC link canal project is
MOHANPURA DAM PROJECT
delayed or is not materialized, than too construction of Mohanpura major dams and RS dam can be taken up
independently or as a complex for the overall interest of the state of M.P. Construction of these two major
dams and reservoirs will be in a cascade pattern on main river and both of these two project are very much
essential to raise the irrigation in sub basin area besides meeting out day by day increasing domestic and
industrial demand.
The topographical and geographical constraint of the upper Chambal basin together with the most
troublesome issue of submergence of land and property calls for a detailed reservoir capacity feasibility
survey for the proposed project so that the interest of the State of M. P. can be taken care off in respect of
minimizing the submergence of land and property.
The Govt. of M.P. with this primary objective has accorded the administrative approval vide
its memo. No 22(A)20/01/SCS/31/2060/Bhopal of dated 11.09.07 for 140.43 lakh. Technical
sanction to Rs120.00lakh was accordingly accorded by Chief Engineer Chambal Betwa Basin
Bhopal vide memo no538/427/D-2/W/CB/07 Bhopal of dated11.10.07 to carry out this work.
The Govt. of M.P. with this objective has accorded the administrative approval vide its memo. No 22(A)303/2014/MPS/31/1476 Bhopal dated 13.10.2014 for Rs. 3448 Crore. The Ministry
Environment, forest and climate change, Govt of India has accorded the environmental clearance for C.C.A.
58040 Ha. And G.C.A. 82625 Ha. Vide its memo No. J-12011/42/2011-IA.I dated 14th
January 2015, but
due to change in irrigation system from gravity canal system to pressurized irrigation system average
irrigation efficiency has increased from 60% to 85%. Due to increase in efficiency C.C.A. has increased
from 58040 Ha. To 125000 Ha. , therefore revised environmental is being sought.
Pressurized pipeline supplying sprinkler and micro irrigation system in the Mohanpura major
project offers the opportunity for high efficiency irrigation, meaning that more cultivable land can
be brought under production. This is the basis upon which the planned CCA of Mohanpura mojar
project was increased from 58040ha to 125000ha.
MOHANPURA DAM PROJECT
CHAPTER-2
PROJECT AT A GLANCE
1.0 General Report
Mohanpura project is a major multipurpose project, which is proposed, in lower Chambal basin in
lower zone-I. The project is proposed on river Kalisindh which is one of the major three river constituting
this zone of lower Chambal sub basin. Under the scope of proposed project a barrier is proposed to be
constructed on river Kalisindh near village Balaheda of Zirapur tehsil of district Rajgarh.The proposed dam
site can be located at latitude230-55’-41’’ and longitude 76
018'15''on Topo sheet no 54D/4.The site is
approachable from Km 42 of Zirapur - Pachor road by a 10.0km long road.
APPROACH TO BALAHEDA VILLAGE AND SITE (PMGSY ROAD)
The site is 26km from Zirapur town. The approach up to dam site from right flank is a PMGSY road
which ends up to the right bank of the river.
MOHANPURA DAM PROJECT
The project is second major dam which is proposed on the main river. The first dam is Ranjit Sagar
dam which is proposed in the initial reach of the river in district Shajapur basically as a irrigation project
whereas the project under reference is to be designed as a irrigation cum diversion structure under the
topographical limitation of the river and sub basin and in particular the gross surplus availability of water
taking into consideration.
The project in its proposed form will provide irrigation on d/s of proposed Mohanpura dam on left
and right flank of Kalisindh River. The irrigation will be provided by pressurized irrigation system nearly
serving 125000ha in the districts of Rajgarh and Shajapur.
The planned use of pressurized pipeline supplying sprinkler and micro irrigation system in
the Mohanpura major project offers the opportunity for high efficiency irrigation, meaning that more
cultivable land can be brought under production. This is the basis upon which the planned CCA of
Mohanpura mojar project was increased from 58040ha to 125000ha.
The project proposal will comprise of following main components: -
1) Construction of dam for 2655 m. This will consist of left earthen dam in 2335 m length
and right earthen dam in 320 m length , and subsidiary bund in a saddle of 2 km .
2) Construction of a central gated spillway in 345m length which will consist of 11 no’s of
17x12m size radial gates and 10piers of 3.5m thickness each.
3) Construction of right and left NOF in 120m length wherein5 blocks of 20m each will be
provided in left flank and1 blocks of 20m each will provide in right flank.
4) One no of head sluice on left flank and one no. of head sluice on right flank from dam to provide
irrigation on d/s of dam to approx. 125000ha of CCA.
5) One no of under sluice in pier number 9 to provide drinking water facility and release of water for
d/s .for maintaining ecological requirements.
6) 350m long 7.50 m wide T-beam Type double lane Bridge over the spillway.
7) 10m long key wall on left earthen dam site at junction between earth dam and spillway.
8) 11 no's of radial service gates of size 17x12m (10+1stand by) with electromechanical rope
drum hoisting arrangement. Alternatively this can be provided with hydraulic hoist.
9) 1 no's of emergency gate consisting of 8 multiple units of 17x 1.35m each and 1 top unit of
17x1.2m with gantry crane type of hoisting arrangement.
10) D/S energy dissipation arrangement in the form of slotted roller bucket of 15m radius.
MOHANPURA DAM PROJECT
11) Construction of d/s training wall, guide wall and returned wall.
12) Construction of diversion barrage and channel from Lakhundar river .
13) Construction of complete left bank & right bank pressurized irrigation system including
rising main, pump house, transmission line including construction of all the pressurized
structure required therein.
The project on its completion will serve to meet irrigation requirement of 125000 ha of
CCA.
The dam in its present proposal will also be able to take care of meeting out domestic & industrial water supply demand to the adjoining towns situated on the periphery of reservoir in M.P., besides other fringe benefits of ground water recharge, flood control, psyculture and tourism.
Construction of Mohanpura dam is also essential for reducing the
effect of likely flood damage in
Kalisindh sub basin to a great extent.

CHAPTER – 4
INTRODUCTION The river Kalisindh is among three major rivers of lower Chambal basin which forms upper reach of
lower Chambal sub basin. This is the biggest river of zone I of lower Chambal basin. The total C.A.
of the river is 24,663.00 sqkm and this shares 18.60 % of the total C.A. of the main Chambal River.
The C.A. of river up to proposed dam site is 4925.00 sqkm.The river is basically an interstate river, and out of its total length of 351.00 kms the river in its first 180.00 km length right from its origin to the
state boundary runs in the state of M.P and the remaining 171.00 km length lies in the state of Rajasthan.
The river has number of major tributaries out of which Lakhundar lies completely in the state of M.P.
The project proposal in its present form includes diversion and transfer Lakhundar sub basin available water in to main sub basin by constructing diversion barrage, for optimum utilization of water
wealth as good storage site is available on river Lakhundar, whereas other tributaries like Ahu, Parwan,
Chauli, Rewa, Piplaud, Amajhar lies fully in the state of Rajasthan except river Kanthal, which is a interstate
river. Except Lakhundar and Kanthal all other major tributaries are originating within the state of Rajasthan and are meeting in the river Kalisindh after traversing through the state
of Rajasthan. The river finally meets into the river Chambal near kota town in the state of Rajasthan
d/s of Kota barrage at an elevation of 195.00m and the riverChambal finally joins river Yamuna
forming the great Yamuna sub basin as a part of GangaBasin.
The Kalisindh sub basin supports a large medium dense habitat area almost equally distributed on both of the banks. The CCA 125000 ha area is proposed under cultivation. Thus, basically the
basin is agricultural predominant basin having very less forest cover. Owing to this cultivation intensity the
basin also supports fairly dense human and live stock population.
Despite fairly good availability of dependable water in the natural stream due to good dependable
rainfall not much of the area is brought under assured irrigation in the basin and most of the culturable area
is rain fed. The situation turns critical in respect of agriculture as 90-95% of
MOHANPURA DAM PROJECT availability of rain is concentrated in three months (July-sep.)
MOHANPURA DAM PROJECT
and the river Kalisindh and its all tributaries all practically having negligible water beyond October for Rabi
crops.
A view of River Kalisindh in Summer
This situation has occurred due to non construction of any major/medium dam project on the river
Kalisindh and even as on today, only four small medium irrigation project namely Tiller, Lakundar, Chiller,
Pipalia Kumar has been constructed on the tributaries of river Kalisindh and only one major irrigation
project RanjitSagar is now proposed on main Kalisindh river other than the Mohanpura dam.
Unfortunately not many good site are also available for construction of major/medium storage
irrigation project on river Kalisindh itself as the river after its origin traversing initial reach mostly runs
through plains Similar situation exists in case of Lakhundar river. Therefore the solution lies in the
construction of dam at proposed site with diversion of its tributary water in it to create a sizable reservoir.
Another view of River Kalisindh in Summer
MOHANPURA DAM PROJECT
It is with this concept the present project report has been prepared for the Mohanpura dam which will
act as a storage reservoir to meet out irrigation demand for approx. 125000ha CCA by pressure irrigation on
d/s of dam in Kalisindh sub basin in M.P.
MOHANPURA DAM PROJECT
CHAPTER – 5
PHYSICAL FEATURES
1 General Report
The Mohanpura project is a new major multipurpose project proposed on river Kalisindh by
MPWRD which is a right bank tributary of river Chambal. The river Chambal is a right bank principal
tributary of the river Yamuna. The river Kalisindh lies and form part of lower Chambal basin and it joins
ultimately in river Chambal, which finally meets river Yamuna. The whole of the catchment, of Kalisindh
sub-basin lies between North latitudes of 22035’ and 24
010’ and East longitudes 75
050’ & 76
040’. The
Kalisindh river rises at an elevation of 610 m from Barziri hill in
the Bagli tehsil of the Dewas district in Madhya Pradesh and traverses to a total length of 351 km before finally meeting with river Chambal, out of the total length 180 km lies in Madhya Pradesh
and the remaining 171km falls in Rajasthan. Thus the river is basically is a inter state river. The average bed slope of Kalisindh river is 0.15%. The catchment area of Kalisindh up to its confluence with
Chambal is 24,663sq km and out of this 12358sqkm area falls in the state of M.P. The area up to proposed
Mohanpura dam site is 3850 sq km. The whole of the catchment area up to the proposed dam site falls under
the state of Madhya Pradesh .The districts covered by the sub basin under the proposed dam are Ujjain,
Dewas, Shajapur and Rajgarh in Madhya Pradesh. Lakundar river is the main tributary of river Kalisindh
and the dam is proposed just down stream of the confluence of these two river.
The proposed Mohanpura dam site is located in Balaheda village of Zirapur tehsil of Rajgarh district
in Madhya Pradesh. Its latitudes and longitudes are 23055’41’’N and 76
018’ 15’’E respectively. The
Kalisindh sub basin up to Mohanpura lies between the 22035’ and 24
010’ and East longitudes 75
050’&
76040’. The length of river up to Mohanpura dam site is nearly 150km.
2 Drainage basin
The catchment area of Kalisindh sub-basin up to Mohanpura dam site is 3850 sqkm,and 1075sq km
diverted catchment of lakhundar , total 4925sq km which is 19.86% of the total sub-basin area
MOHANPURA DAM PROJECT
of Kalisindh. The length of Kalisindh river up to proposed Mohanpura dam site is, approximately 150 km.
The final dam site is situated in the close proximity of the state boundary and after travelling nearly 30km,
the river enters in the state of Rajasthan. The sub-basin has Deccan trap as the main rock belonging to the
middle series of the fold classification with simple AA flows without tectonic imprint and dykes and pertains
to the cretaceous coocene age. The rocks have their origin in the erruphin of theletic magma probably in the
beginning of third era. The formation comprises of taped flow of varying thickness. The major part of the
basin is occupied by the hard rocks belonging to age ranging from Achaean to upper retacesins and
represented by granites, granitic gneisses, schist’s, phyllites, quartzite’s, slates, sand stones, lime stones,
basalt and conglomeratic rocks.
A view of Fractured rock available in river bed
3 Soil types
The soil type in the catchment area and too a greater extent in command area is mixed red and black
as per the general classification. A brief description of the soil in the Kalisindh and sub-basin are given in
the following paragraphs.
MOHANPURA DAM PROJECT
A view of Soil cover available in Command Area
Soils on hill and hill ridges (Entisols)
These soils are fine loamy to coarse loamy in texture and grayish brown to dark reddish brown in colour. They are highly, excessively drained, stony and gravelly in nature. These soils are
of shallow depth with low nutrient status and are slightly acidic to neutral in reaction. They are low in organic matter content and have poor water retention capacity. These soils are unsuitable for normal crop
husbandry. However, they may be utilized for forestry, pasture development and growing grasses.
These soils occur of level to gently undulating terrain. They are yellowish brown to dark brown in
colour. These soils are shallow to deep, coarse to fine medium textured with low nutrient status. These soils
are moderately eroded. Their water retention capacity varies with the soil texture and organic matter content.
In this category too the shallow soils are unfit for normal crop husbandry whereas deep soils are suitable for
growing Kharif crops like Sorghum, millets, pulses, bajra and cowpea.
MOHANPURA DAM PROJECT
Pediment soils (Entisols and Vertisols)
These soils on gently to undulating gneissic terrain comprising the vast pediment and
pediment plains characterized by intermittent rocky wastelands and shallow water bodies. They are
shallow to deep coarse to fine medium on texture and poor in nutrient status. They are moderately eroded. The deep soils in this category are fit for cultivation of crops like sorghum, till, bajra, millets and
groundnut. Shallow soils are best suited for raising pastures.
Soils of level alluvial plain and undulating flood plain (Inceptisols and Vertisols)
These soils occur on level to undulating terrain. These are deep to very deep, fine to fine loamy, well
to moderately drained and contain calcium carbonate deposits. They are low in organic matter content and
suited to crops like jowar, arhar, soyabean and moong under dry land and sugarcane under irrigated
conditions. Wheat, gram and linseed may be grown during the Rabi season soils of disseeted flood plain (Inceptisols)
These soils are very deep, well drained, calcareous, and gravelly with abundant lime nodules
in the soils. These are fine loamy in texture, yellowish brown Colour with low organic matter content. They possess moderate water retention capacity. These soils are severely eroded during floods and
need extensive conservation measures. Land situated away from the streams can be put under cultivation for
Kharif crops viz jowar, bajra and arhar.
4 Population
The sub-basin is having medium to dense population on the upstream as well as on the down stream. The average density of population approximately 150 person/sqkm. On an average a
population of nearly 7.5 lakh is likely to be benefited (directly or indirectly) by the project by the
end of year 2050.
Despite high intensity of irrigation in the sub-basin, owing to the typical land holding pattern
sufficient work force for the proposed construction of dam and its appurtenance will be available
MOHANPURA DAM PROJECT from the categories of marginal farmer’s, land less agricultural laborers and other laborers engaged in part time small works.
A view of habitants in Kalisind Basin (Zeerapur)
5 Natural resources
Except agricultural based land resources, there are number significant mineral or other
natural resources available in the basin area. Some agricultural product based industries has come up in recent past mainly like soyabean oil producing units, textile units etc. Some small-scale industrial areas
are also opened in Rajgarh, Shajapur and Ujjain district. However one of the biggest industrial area i.e.
Dewas is situated on the periphery of the basin and large no of major industrial unit are situated in this area.
Another medium size industrial area at Maksi has come up in recent past which is situated with in the basin
boundary. The forest cover in the basin is very poor and is of scattered type can be classified as forest with
open shrubs.

SURVEY AND INVESTIGATIONS
General
Newaj River is a tributary of the Chambal basin. The Chambal
basin extends over an area of 139,468 sqkm and lies to the
north of the Vindhya range, the basin covers large area in the
states of Madhya Pradesh and Rajasthan and a small area in
Uttar Pradesh.
The state-wise distribution of the drainage basin of the river is
given:
Madhya Pradesh : 57,948 sqkm
Rajasthan : 80,670 sqkm
Uttar Pradesh : 850 sqkm
TOTAL : 139,468 sqkm
The Chambal which is the principal tributary of the Yamuna,
rises in the Vindhya range near Mhow in the Indore district of
Madhya Pradesh at an elevation of 854m of north latitude
22°28'and east longitude 75°40' and flows in a general in north
direction. In Madhya Pradesh, Rajasthan border reach, near
Chamla the Siwana and the Retam join the river from the left
and the Kshipra and the Chhoti kalisindh form the right, the
river then enters Rajasthan and after flowing for a length of 38
km, turns to the right and takes a north easternly course. At 480
km from the source, it receives a major tributary from the right
MOHANPURA MAJOR PROJECT
126
the Kalisindh, and 22km below another tributary the Kural
form the left, the river continues to flow in a north easterly
direction for a further distance of 40km, when it is joined by its
other right bank tributary, the Parwati .The Banas, a major left
bank tributary joins the Chambal in this reach, near the village
of Kameshwar.
The river Newaj is among three major rivers of lower Chambal basin
which forms upper reach of lower Chambal sub basin. The river is
basically a interstate river, and its first 205km length right from its
origin to the state boundary falls in the state of M.P. The river has
two major tributaries which lies completely in the state of M.P.
These are Dudhi river and Sukad river. The other major tributaries
are Chhapi, Gharganga, Ghodapachhad, and Ajnar all of these
tributaries are though originating within the state of M.P. but are
meeting in the river Newaj after traversing through the state of
Rajasthan. The river, after the junction of all these tributaries is then
called river Parwan and finally meets into the river Newaj near Baran
in the state of Rajasthan (Basin map of Rivers traversing in M.P. is
enclosed). The Newaj finally joins river chambal on upstream of the
confluence point where the river Parbati meets river chambal.
The Newaj sub basin supports a large area almost equally distributed
on both of the banks. The GCA of the Newaj sub basin is 431000ha
and out of which approx.288000ha area is under cultivation. Thus
basically the basin is an agricultural predominant basin having very
less forest cover. Owing to this cultivation intensity the basin also
supports fairly dense human and live stock population.
In this basin farmers are dependent on the rainfall and most of the
culturable area is rain fed so assured irrigation is not in the most of
the area. The situation turns critical in respect of agriculture as 90-
MOHANPURA MAJOR PROJECT
127
95% of availability of rain is concentrated in three months (July-
September) and the river Newaj and its all tributaries are practically
having negligible water beyond October for Rabi crops. This
situation has occurred due to non construction of any major or
medium irrigation project on the river Newaj even as on today. Only
one small medium irrigation project namely Dudhi has been
constructed on one tributary of river Newaj and second is
Kushalpura Medium Multipurpose Project. Unfortunately not many
good sites are available for construction of major/medium storage
irrigation project on river Newaj. Therefore the solution lies in the
alternative of construction of possible minor irrigation tanks,
construction of big stop dam cum barrage on river Newaj and its
major tributaries and to construct a big storage reservoir on river
Newaj where topography permits.
CLIMATE
In the year, four distinct seasons seems in the basin. They are (i)
the cold weather (ii) the hot weather (iii) the south-west
mansoon and (iv) the post monsoon.
RAINFALL
The maximum and minimum annual precipitation in the
Chambal basin varies from 1, 270 mm to 356 mm.
SOILS
General data regarding the soils of India's indicates that mainly
medium black, mixed red and black and red and yellow soils
occur in the basin.
WATER RESOURCES
The surface water potential of the Chambal river system had
MOHANPURA MAJOR PROJECT
128
been first assessed in 1949 on the basis of Khosla' formula. The
annual run off of the river was estimated to be 33,908Mcum. In
1960 when the irrigation potential studies of the country were
made by the central water and power commission, the total
annual runoff of the Chambal river system was assessed to be
24,312 Mcum.
3.5 HYDROLOGY
Statistical data of 11 R.G.stations are available for last 45
yrs. The monthly rainfall data of these rain gauge stations for
varying periods from 1966 to 2010-2011 were used in working
out the dependable rainfall values at various percentages and
according the yield by rainfall - runoff relationship.

All the above mentioned Rain gauge stations are
influencing the Aklera Gauge and Discharge site which is
maintained by CWC.
Out of 11 Rain gauge stations, 8 rain gauge stations in and
around the catchment area upto the proposed dam site, which
influence the yield upto proposed dam site. These rain gauge
stations are Khilchipur, Rajgarh, Biaora, Narsinghgarh,
Sarangpur, Shujalpur, Astha and Sonkatch.
The normal annual rainfall of the Newaj sub-basin upto
Mohanpura dam site is 956.76 mm. The monsoon rainfall
constitutes as much as 90% of annual rainfall. The maximum,
minimum and the average monsoon weighted rainfall values are
2036.75mm, 323.00 mm and 886.00mm respectively for the
period from 1966 to 2011.
Comparison of rainfall and runoff :-
The principal comparison of runoff (steam flow) and rainfall is done through hydrological modeling. A quick insight into the consistency of the data could also be made by graphical and tabular comparison of aerial rainfall and runoff. In the analysis, the basin rainfall over an extended period such as a month of year should exceed the runoff over the same period by the amount of evaporation and changed in storage in soil and ground water. Graphical comparison should be with physical changes. The annual rainfall runoff in unit of MCM plotted in fig 2.5 for Alkera G.D site. The period is from1977-2008

The average percentage of monthly yield and monthly rainfall to the respective annual values of Aklera gauging site are plotted in Fig 2.8. It can be observed that although rainfall in less in October the yield during this month is substantial. Hence five June (June to October) were consider as the monsoon season for the study area. The separated monsoon virgin yield at Aklera are presented in Fig 2.9 . The average non-monsoon yield was estimated to be 7.52% of the monsoon yield.

Processing of Runoff Data :-
For this study types of runoff data are used : (i) monthly runoff series, (ii) Annual Maximum Series (AMS), and (iii) Short-term (hourly) data. Monthly data used for water balance, consistency check, and rainfall-runoff modeling and the annual maximum data are used for return period flood estimations using AMS modeling. The short term data, i.e. the hourly runoff data are used for design flood calculation using the unit hydrograph technique. The following section discusses in detail the consistency of the given of the data. The annual observed in virgin flow series in Alkera is shown in Fig. 2.7 .

WATER AVAILABILITY STUDIES
GENERAL:-
The proposed Mohanpura Major
Multipurpose Project consist of construction of a dam across
Newaj River of Chambal Betwa Basin . The Mohanpura Major
Multipurpose Project is having Longitude as as76046’37”E &
Latitude 23057’54”N. Toposheet No. 55A/13. The Catchment area
of Mohanpura Major Multipurpose Project is 3825 Sq km.
The water availability at the proposed dam site is
worked out by usual procedure & 75% dependable yield is
calculated from it. The detailed methodology, calculations
etc. are described below:
METHODOLOGY:-
There is no observed gauge-discharge data available at
the proposed dam site, however there is a gauage-discharge
site available on same river Navej known as Aklera GD site
maintained by CWC having catchment area of 6050 sq.km.
The discharge data at Aklera GD site are available for about
31 years from 1977-78 to 2007-08, In the upstream of Aklera GD
site considered and added runoff data of existing tanks 2Nos out
of 6 Nos of Tank from years 2001-2008 are namely Phudra,
Panchapura, Kunwarchain sagar, Gulendi(Rajasthan),
Kalikhar(Rajasthan), Prithvipura Tank (Rajasthan) (given on
page to ). Efforts have been made to derive Rainfall-Runoff
relationship using the discharge data of Aklera GD site and 11
MOHANPURA MAJOR PROJECT
134
No Rain gauge stations are influencing the catchment area of
Aklera GD site are namely Aklera, Manohaar, Thana,
Chachuaura, Khilhipur, Rajgarh, Biora, Narsingharh,
Sarangpur, Shujalpur, Ashta and Sonkach (given on page to
) & same R-R Equation is used to estimate yield at the
proposed Mohanpura dam site. There are 8No of Rain gauge
stations influence the catchment area of proposed
Mohanpura dam site namely Khilhipur, Rajgarh, Biora,
Narsingharh, Sarangpur, Shujalpur, Ashta and Sonkach ( given
on page to ) The rainfall data of these stations are
available for a period of 45 years (1966-67 to 2010-11) for
deriving the yield.
For this particular project, the consistency of
available rainfall data has been checked using different methods.
For checking consistency, Yearly rainfall of index station and
average of other stations has been taken for yearly. The plotting
of double mass curve is enclosed. The double mass curve shows
a fairly consistent straight line relationship. The line is very slight
curve at beginning or at end, but the coefficient of co-relation is
very good. This indicates that the data is fairly consistent which
needs no correction only one rain gauge station Chachaura is
required to check for consistency.
Rainfall data of all R G station has been checked
for consistency by double mass Curve analysis and rainfall
data of only Chachaura RG station is corrected, details of
mass curve are enclosed Fig 1.8 to 2.0 (given on page to )

stations and influence factors are worked out for these
stations. (given on page to ) Weighted rainfall for the
catchment is worked out by applying the influence factors
to rainfall of these rain gauge stations.
The month wise R-R equation for individual
Monsoon months (June to Oct) and Non monsoon Months is
developed using the discharge data & concurrent weighted
rainfall data at Aklera GD site. The equations so derived are
as follows:-

136
Shujalpur, Ashta and Sonkach. Influence factors are worked
out for these stations for the catchment (given on page to ).
Applying the influence factors to rainfall of these rain gauge
stations, weighted rainfall is worked out. Month -wise
R-R equation is applied to the derive long term series. Thus a
month wise series of runoff (yield) is obtained at the proposed
Mohanpura dam site. Yearly annual inflow (yield) at the
proposed dam site is computed by adding all monsoon month’s
runoff and non monsoon runoff .

This yield is arranged in descending order for
working out 75 % dependable yield. Obtained yield is 749.709
Mcum which gives a yield rate of 0.196 mcum/sq.km.
Thus the adopted 75 % dependable yield as 749.71

EXISTING USAGE : UPSTREAM
As per Indicative master plan of Chambal- Betwa
Basin of above computation 75% dependable water yield
was computed adopting yield factor of 0.19 MCM/Sq.Km
of the catchment area. Yield computed with the help of
observe data of Aklera GD site on Rainfall-Runoff Relationship.
The use of this available yield (1772.51 MCM ) is shown as
under:
Existing schemes 76.80 MCM
Under construction scheme 0.00 MCM

Surveyed/under surveyed 14.64 MCM
Proposed scheme
91.44 MCM
Domestic use 10.00 MCM
Industrial use 20.00MCM
Ecological Balance 10.00 MCM
Total: - 40.00 MCM
Thus out of 749.71 MCM yield 616.27 MCM was
total uses as per Master Plan.
RIPARIAN RIGHTS:-
No specific riparian rights are available in the
records. However the inhabitants of the area will be allowed to
use water for domestic and other nistar purposes from rivers
and nallas in the catchment and command area as per
present usage by them. No rights however will be given to the
inhabitants for usage of water from the proposed reservoir or its
canals. To maintain environmental flow in the downstream of the
river, regulated releases (52 MCM/ year) will be done.
From above yield study it is clear that sufficient
water is available. From area capacity table gross capacity at
FRL will be easily meet from available water in monsoon
period.
DRAINAGE
The total catchment area of Newaj sub-basin up to Mohanpura dam site is
3825.00 sq km, which is 63.22% of the total sub-basin area up to G & D site.
MOHANPURA MAJOR PROJECT
140
The length of Newaj river up to proposed Mohanpura dam site is,
approximately 190.00 km. The final dam site is situated in the close
proximity of the state boundary and after travelling nearly 67.00 km, the
river enters in the state of Rajasthan. The sub-basin has deccan trap as the
main rock belonging to the middle series of the fold classification with
simple AA flows without tectonic imprint and dykes and pertains to the
cretaceous coocene age. The rocks have their origin in the erruphin of
theletic magma probably in the beginning of third era. The formation
comprises of taped flow of varying thickness. The major part of the basin is
occupied by the hard rocks belonging to age ranging from Achaean to upper
retacesins and represented by granites, granitic gneisses, schist’s, phyllites,
quartzite’s, slates, sand stones, lime stones, basalt and conglomeratic rocks.

Soil types
The soil type in the catchment area and too a greater extent in
command area is mixed red and black as per the general classification. A brief
description of the soil in the Mohanpura and sub-basin are given in the
following paragraphs.
MOHANPURA MAJOR PROJECT
141
A view of Soil cover available in Command Area
Soils on hill and hill ridges (Entisols)
These soils are fine loamy to coarse loamy in texture and grayish brown to
dark reddish brown in colour. They are highly, excessively drained, stony and
gravelly in nature. These soils are of shallow depth with low nutrient status
and are slightly acidic to neutral in reaction. They are low in organic matter
content and have poor water retention capacity. These soils are unsuitable
for normal crop husbandry. However, they may be utilized for forestry,
pasture development and growing grasses.
These soils occur of level to gently undulating terrain. They are yellowish
brown to dark brown in colour. These soils are shallow to deep, coarse to
fine medium textured with low nutrient status. These soils are moderately
eroded. Their water retention capacity varies with the soil texture and
organic matter content. In this category too the shallow soils are unfit for
normal crop husbandry whereas deep soils are suitable for growing Kharif
crops like Sorghum, millets, pulses, bajra and cowpea.
Pediment soils (Entisols and Vertisols)
These soils on gently to undulating gneissic terrain comprising the vast
pediment and pediment plains characterized by intermittent rocky
MOHANPURA MAJOR PROJECT
142
wastelands and shallow water bodies. They are shallow to deep coarse to
fine medium on texture and poor in nutrient status. They are moderately
eroded. The deep soils in this category are fit for cultivation of crops like
sorghum, till, bajra, millets and groundnut. Shallow soils are best suited for
raising pastures.
Soils of level alluvial plain and undulating flood plain
(Inceptisols and Vertisols)
These soils occur on level to undulating terrain. These are deep to very
deep, fine to fine loamy, well to moderately drained and contain calcium
carbonate deposits. They are low in organic matter content and suited to crops
like jowar, arhar, soyabean and moong under dry land and sugarcane under
irrigated conditions. Wheat, gram and linseed may be grown during the Rabi
season soils of disseeted flood plain (Inceptisols)
These soils are very deep, well drained, calcareous, and gravelly with
abundant lime nodules in the soils. These are fine loamy in texture, yellowish
brown Colour with low organic matter content. They possess moderate water
retention capacity. These soils are severely eroded during floods and need
extensive conservation measures. Land situated away from the streams can be
put under cultivation for Kharif crops vizjowar, bajra and arhar.
COMMAND AREA
COMMAND AREA DEVELOPMENT PLAN
Principles of Macro – Micro Irrigation Network Planning
As a part of the Command Area Development Plan, Village Service Area
(VSA) concept shall be commanded by a separate minor with a view to
organize and maintain byfarmer’s water co-operative societies. A minor shall
serve the area of about 250 – 500ha belonging to a single village. In this
MOHANPURA MAJOR PROJECT
143
concept, village boundary serves as a command boundary of a minor.Minor
service area (MSA) means that CCA falling under a minor shall cover more
thanone village. In this concept, irrigation of CCA 250 – 500 ha of single
village is considered.However, area confined by topographical and hydraulic
boundaries shall get water fromthe minor.In VSA / MSA, it is implied that the
canal system is to be maintained and operatedincluding revenue collection and
water user’s association on co-operative basis would do equal – distribution of
water among farmers.The alignment of distributary and its minors shall be
planned on a combined village map.The distributary block shall be decided on
the basis of area covered by natural drains/watershed. The minors are planned in
such a way that one minor may cover area of asub water shed / shed drains, and
is called VSA / MSA. The area of a VSA / MSA shallrange from 250 to 500 ha
and preferably covers one village. However a VSA /MSA maycover area of
more than one village and conversely these may be more than one VSA /
MSA in a village. The VSA / MSA shall be further divided in chaks. The chak
size is keptaround 40 to 60 ha depending upon the topography. The chak shall
be formed in such away that the shape a chak be around rectangular having
length (length may be doublethe width approximately) perpendicular to canal to
minimize the length of canal network.
Planning Distribution Network
First ridges and valleys are marked on combined village map – Ridge
lines shall be tentatively taken as gravity pipe lines, whereas valley lines shall
be taken as boundary lines. Pipe lines be so considered that the distance
between distributary and minor may be around 1.0 km and distance between
minor to minor be around 2.0 km. Further, as far as possible distributary may be
centrally in the watershed and minor be centrally in the sub-watershed, implying
there shall be both side command of a minor as well as a distributary. However,
topography would be the governing factor to decide the alignment of a
distributary and its minors in a watershed block. Tentative VSA boundaries
shall be marked around a canal / minor. Similar exercise is done in the whole
area under a distributory. Alignment of each minor shall be finalized within the
permissible area limit. Similarly the alignment of distributory shall be finalized
keeping the requirement of minor’s. Minor – Changes / Adjustment be made in
the alignment of minors & distributary
wherever needed. Tentative L-Section is prepared for minors and distributary.
HGL line shall be marked, on NSL profile keeping in view the HGL required at
different point on minors and the distributary, and keeping the 1.20m below
ground level. W.S.S. be proposed matching with the ground but with in
permissible velocity limit. L-Section shall be finalized with Micro-network
planning. Gravity pipe line construction cost is directly related with gravity pipe
length per hectare of CCA. Not only the cost which is one time expenditure but
head losses which would be minimized by reducing the gavity pipe length per
hectare of CCA. In order to reduce the gravity pipe line length the system shall
MOHANPURA MAJOR PROJECT
144
be straight as far as possible and commanding both sides equally. Chak size
plays a very important role in planning distribution network. Bigger the chak
size less pipe network length and smaller the chak size more the pipe length. In
case of 40 to 20 ha chak size, length of distribution network may be around
40m/ha under VSA /MSA concept.
Micro network and Layout
The main objectives of a properly planned micro network and drainage
network are:-
Micro network must be minimum in length, commanding maximum area,
involving minimum head losses and having scope for land grading and
shaping.
To be able to drain away the surplus water quickly.
The first requirement for the planning and layout of micro irrigation system and
drainage network below the chak outlet is the preparation of complete and
accurate contoured village map on a suitable scale preferably 1:4000 and
contours at 1.0 m intervals depending upon the topography. In addition to the
contours, the following
information shall also be shown on these maps:-
Towns, Villages and hamlets with their boundaries
Existing ponds, irrigation tanks with their irrigation networks.
Existing roads, railway lines etc. location of drainage crossings under
existing roads and railway lines
Natural drainage and valleys
Cart tracks and cart tract cum nalla
Existing open wells, tube wells
Government land, forest land, waste land, uncultivable land and un-
commanded land to be excluded from the service area. After showing the
above details, step by step procedures shall be followed for
planning the layout of the micro irrigation and drainage system shall be as
under:
A well defined ridges, valleys and drainage often govern the chaks and sub
Chaks boundary; these shall be marked on the map before starting the layout
planning.
Keeping the well defined natural drainages and valleys in view, chak
Boundaries shall be demarcated. As far as possible, outlet command shall be
located on one side of a road, railway line or canal to avoid too many
crossings. Chak boundaries shall normally be planned along boundaries of
survey number and be located in one village.
The chak command shall then be sub-divided into suitable number of sub
Chaks (4 to 2.5 ha each). Simultaneously planning for the watercourse
alignments with its branches or arms is done. It is best to plan a exit pipe
across the highest contour and laterals down the command slope.
MOHANPURA MAJOR PROJECT
145
Within the limitations of topography, chaks and sub chaks shall be carved.
The governing criteria shall be maximum command with least length and
minimum head losses in the exit pipe.
Direct outlets from distributaries shall be provided in exceptional cases. A
Minor shall tail off with 2 or more outlets.
Turnout is a gated, fairly watertight division box, feeding a sub-chak of 5 to 8
Ha of a chak.
The existing irrigation tanks in the service area shall be integrated in the
exit pipe layout. The purpose of village storage facility is to ensure a
local supply during off period.
Exit pipe shall be planned with a minimum 20m residual head by considering
velocity ranges from 1.5 m/s to .60 m/s. Different exit pipe reaches
could be given different bed gradients depending on topography.
As the discharge of a chak is to be passed into each branch of the exit and
the outlets (with in sub-chaks), the section of the entire micro system
shall be designed for the same carrying in a chak.
Required water level at the head of each turnout shall be worked out. The
required residual head shall be traced by adding head loss, of the last field
NSL proposed to be irrigated.
If the water level computations do not satisfy the criteria, carryout the
Necessary adjustment and finalize the micro system layout for the chak.
CCA shall be assessed on long term basis with development of cultivation
There would be drastic change in topography. Most of the lands would be
leveled, graded and shaped.
CCA shall be calculated on the basis of average NSL (Natural Surface Level)
of the individual holding / survey no. Only very high patches that may not be
economically leveled may be taken out off command. Although as a principle,
no area within command is left out off command only on the basis of high
levels.
Discharge shall be calculated on the total CCA as computed above in a chak
multiplied by the BDC as applicable for that region. This would give
discharge at outlet head.
Length of Minor shall be divided in suitable reaches, depending upon head,
no. of outlet in a reach. It may be ensured that there may not be appreciable
drop in head at end of a reach, due to withdrawal by outlets in that reach.
Provision for drainage needs of access roads:
The following guidelines shall be used for planning the drainage network:
While planning drainage network, it shall be born in mind, that there would
be a sea change in the topography with the induction of canal water.
Generally the drainage networks shall be located 200 to 400 m apart in flat
countryside and closer in steep and undulating lands.
Where Nallas are used as access roads, separate provision for roads shall be
needed.
MOHANPURA MAJOR PROJECT
146
Field roads/cart tracks shall be planned so that farmers have access to every
chak, and preferably to every sub-chak.
Where new field roads are planned, these shall be constructed on the sides of
minors.
Control Structure at Distributory Head
The level of structuring is defined as the point in the system below which
flows either ON or OFF. Larger structured blocks mean less internal regulation
and easier management. However optimum production per unit of water shall be
obtained by an equitable spreading of the available water without reference to
individual chak requirements and to achieve this end the large structured block
is well suited. Whatever the internal distribution detail, it is fundamental to the
concept that every farmer shall know in advance of each season, how much
water will be delivered to him and when he will receive it. So that he may plan
his area and crops to be sown. It is assumed that structuring is at the distributory
head. Structuring means to provide flow control valves to ensure regulation at
distributory head.
Distribution network
The system below the structured level requires only proportional division down
to the chak level and will be run on, ON or OFF basis. The distributaries,
minors and sub minors therefore, will run either full or will be kept closed.
The turnouts serving sub chak will however, always need to be controlled
valves with On/OFF to enable their rotational running with the full outlet stream
flow in a sub chak.
A distribution system with proportional division run full on or off delivering
to a chak system grouped in minor blocks.
Regulation
Planning of the Macro and Micro Distribution system is based on
rotational running of pressurised gravity pipe with warabandi concept. In this
system, the main and branch pipes will be run full or with the needed discharge.
The distributaries, minors, and sub minors will be either running with their full
supply discharge or will be kept closed discharges less than peak requirements
of distributaries and minors will be controlled by time factor applied to their
running in suitable groups with their full supply discharge.

METHODOLOGY ADOPTED FOR FIELD SURVEY
For assessing the floral diversity in the study area both floristic survey and quantitative
analysis of vegetation were undertaken. The quantitative analysis of vegetation was
done by using quadrats as sampling units. The quadrats were laid randomly in identified
sites (as per project impact) in the dam site, submergence area, Catchment area and
Command area representing different land use types such as forest, garden and
cultivation lands that occurred at a particular site. The vegetation analysis was
MOHANPURA MAJOR PROJECT
152
undertaken by collecting numerical community data for trees, shrubs and herbs from the
randomly laid quadrats. Quadrat size of 10 x 10 m was used to enumerate trees and
shrubs, while herbs were enumerated through 1 x 1 m quadrats. The number of
quadrats laid for different vegetation components at different sampling sites is listed in
Table-7.1.

The River Newaj is not a perennial river but after constructing Mohanpura dam
it will likly to be Perennial . Also the terrain of the command area of the dam
are having undulated topography so the 125000ha. CCA area will be fed by
pressure irrigation system. (This also fulfills the criteria of CWC that for major
dams minimum 10% of the Culturable Command Area should be pressure
irrigation), 125000ha. CCA annual irrigation as 142000 ha.
Thus in this system 100 % irrigation is pressure irrigation, having Irrigation
intensity 113.6%. In this way this project consist three (3) types of irrigation as:
a. Surface Irrigation : Basin Irrigation/Flow irrigation
b. Sub Surface Irrigation : Trench & Perforated Pipes Drip Irrigation
c. Improved System : Sprinkler System
CROPPING PATTERN & WATER REQUIREMENT CALCULATIONS
CROPPING PATTERN
Present Status:
According to the statistical year book – 2010 of Rajgarh district present
cropping pattern (According to the table 3.1 & 3.2) for the proposed command
area of the Mohanpura project (Teh.- Rajgarh, Khilchipur & Sarangpur) mainly
consists Wheat (53.6% of total present CCA), Maize (14.6%), Soyabean
(62.6%) & Fodder etc.
Proposed Cropping Pattern:
It is very obvious that after constructing such a big reservoir farmers’ financial
condition should improve and it is only possible if they go for different crops
rather than present.
Proposed command area of project is nearby to the Shajapur district (approx 60
km). This area is industrial area and further industrial corridor is also
developing. Tehsil Sanwer of district Ujjain is famous for American Corn. Now
a days American corn is also used for different types of dishes so if this would
be irrigated in the command area of the project then it will work as cash crop for
the farmers. This is the reason that in the proposed cropping pattern this crop is
MOHANPURA MAJOR PROJECT
154
poroposed. Further Groundnut and Oil Seeds are also proposed so that variety
of crops may be there.
Orange has also been proposed in the cropping pattern. Bhawani Mandi and
Jhalawad are the nearby area of the command and Bhawani Mandi is the IInd
largest production zone of the orange and called second Nagpur. Once such a
big reservoir like Mohanpura is constructed on the consequence of which
ground water will replenish & farmers can go for the orange cultivation. Due to
this Orange which is a perennial crop has also been proposed. In this way if
farmers go for diversity of crops then this area will develop as the industrial
corridor.
Now a days central government of India is encouraging the production of
vegetables. Also the yields of vegetables are higher as compared to the others.
So it has been also included in the proposed cropping pattern. Details are as
below:
S.No. Type of Crop Season
1 soyabean-2kh
Khariff
2 maize 2 kh (american)
3 maize 1 kh (ordinary)
4 groundnut – 2 kh
5 pulse 2kh
6 vegitable 1kh
7 wheat-olv (ordinary)
Rabi 8 wheat-1mv (high yield)
9 gram - n2ra
10 oil seeds (til, alsi)
11 orange (orchard) Perennial

Crop Water Requirement Calculations
Crop Water is calculated according to the Design Series Technical Circular No
25 & 15 and CWC Guidelines 2010.
According to the Design Series Technical Circular No 25 crop water
requirement mainly depends upon the Evaporation Losses, Crop Factor,
Effective Rainfall, Soil Moisture Contribution, Ground Water Contribution and
Water requirement for Land Preparation. From the command area of the project
district boundary of Guna is nearest (approximately 40km) that is why ETo
value of Guna district has been taken for the calculations. The pressure
irrigation system is designed for drip and sprinkler irrigation system, so
efficiency of the pressure irrigation is taken as 83%. Crop Water Requirement
is calculated fortnightly for 26 years on the above basis. Details are enclosed.
WORKING TABLE
Live Storage Level of the dam is R.L. 398m and the Maximum Draw Down
Level is R.L. 380m. Water will be lifted from R.L. 380m so it can be said that
LSL for pressure irrigation system is 380m. From the Area - Capacity table it is
clear that at R.L. 380m capacity of dam is 39.03 Mcum.
Evaporation Losses according to the Mean Daily Evaporation for every month
is calculated (Fig.5.2 to Fig.5.13) according to CWC- Basin Planning and
Management Organisation guidelines- 2006 entitled ‘Evaporation Control in
Reservoirs’
Working Table is calculated on the basis of the Rainfall & Runoff relationship.
Approval letter of RR relationship is attached. Working Table for 26 yrs is
calculated (19855-86 to 2010-11) out of which only 5 yr (Year 1991-92, 2000-
01, 2006-07, 2007-08 & 2008-09) are water shortage year which is 19.33%.
Hence water planning of project is 80.73% successful which fulfils the CWC
norms for Irrigation & Multipurpose Project. Details are attached.
MOHANPURA MAJOR PROJECT
157
OPERATION TABLE
Pressure irrigation system is proposed for entire command area of 125000ha of
CCA. Working Table & operation table is attached from which it is clear that in
the year 1991-92, 2000-01, 2006-07, 2007-08 and 2008-209 water shortage is
21.24,190.93,14.26,14.26, and 96.15 Mcum respectively. From the working
table it is clear that in 1991-92 water shortage is occurring from Feb- May by
10.79, 2.75, 3.47& 4.24 Mcum respectively. In the year 2000-01 water shortage
is occurring from Dec-May by 57.88, 108.58,14.01, 2.75,3.47 & 4.24Mcum,
2006-07 water shortage is occurring from Apr-June by 3.47,4.24 & 6.55 Mcum.
2007-08 water shortage is occurring from Apr-June by 3.47, 4.24 & 6.55
Mcum. 2008-09 water shortage is occurring from Jan-May by 71.68, 14.01,
2.75, 3.47 & 4.24 Mcum. shortage in these months. From the analysis of
working table and operation table it is clear that from the Pressure irrigation
system can be made up to the December and the shortage in the January month
and onwards. Now, according to the ‘Guidelines For Less Water Consuming
(Leaner) Cropping Pattern For Irrigation System In Drought Prone Areas’ of
Government of India, Central Water Commission, Irrigation Planning
Directrate, New Delhi, April 1992 in drought prone areas, with a fewer than the
optimum number of watering on a larger area and appropriate timing of
irrigation, a greater overall production can be secured. Two blocks of Rajgarh
district are DPAP blocks namely Rajgarh & Khilchipur which come under the
command area of the project and these area will have irrigation supply upto the
December but in leanest rainfall year water will not be supplied from the month
of January. Hence proposed cropping pattern can successfully be implemented
to the project.

FOREST LAND
As stated in the relevant para' s of the report, the entire catchment area and command area of Mohanpura project is having very little forest cover and out of the total area likely to come in the
submergence of proposed Mohanpura dam with FRL of 400m is hardly 5.35% of the total area of 7476 ha coming under submergence even this small percentage of forest area approx. constituting 680 ha
at FRL of 400 m coming under submergence is mainly low to medium density forest and very little
or practically no impact is expected on the flora and fauna and environmental and ecological system of the Kalisindh river basin with the construction of the proposed Mohanpura dam. The necessary permission and clearance for acquisition of this forest area as per the prevailing norms and
guidelines of GOI will be obtained by fulfilling the terms and condition of payment of compensation
in lieu of acquisition and use of forest land. Simultaneously the condition of in lieu of plantation will be satisfied by making suitable provisions in the cost estimate for this project to take care of the said
activity.
The Ministry of Environment, forest and climate change, Govt of India has accorded the forest
clearance for aera 680ha vide its memo F.No. 8-02/2014-FC dated 15.09.2015.

CHAPTER - 8
DEPARTMENTAL INFRASTRUCTURE FOR CONSTRUCTION
The core construction activities for proposed Mohanpura dam are concentrated only in Zeerapur
tehsil of district Rajgarh in M.P. The MPWRD is the sole construction agency for the execution of water
resources works in the state. The present existing setup of MPWRD consist one division office functioning
at Rajgarh (which is also a district headquarter) under the overall control of chief engineer of Chambal Betwa basin. The division strength consists of 4-sub
division with headquarters at Sarangpur, Zeerapur, and Rajgarh, Khilchipur whereas one quality control sub
division also functioning at the Narsinghgarh under the jurisdiction of this division. The division falls under the jurisdiction of water resources circle Guna, where too sufficient
facility with scope of future development exists for office and residential. Two more water resource div. are also functioning in the near vicinity of the proposed project. Out
of this the Narsinghgarh div. is in the administrative control of chief engineer C.B. Basin Bhopal whereas the Shajapur div. is functioning under the control of Chief Engineer Narmada Tapti basin Indore. As per the available work load any of the div. among these three div. can be
conveniently deployed for this work in the initial stage. Later on during the peak construction period a
separate div can also be deployed with its headquarter at Zeerapur / Rajgarh/Sarangpur/Biaora/Narsinghgarh.
All these proposed divisional headquarter is well connected by a network of NH, SH,
MDR etc. and is also having a connecting railway link having its ends terminating on Delhi-Bombay and
Maksi-Maksi railway line at Bhawani mandi and Sarangpur respectively. The site is approachable by Bina-Kota railway line from Biaora railway station. The
existing WRD setup at these places includes office complex and residential complex (colony) along with
ample open space and this facility is just sufficient for taking up for proposed construction of Mohanpura dam project with suitable addition and modification
in the available infrastructure in terms of construction of stores, office, residential building etc. with
minimum expenditure.
MOHANPURA MAJOR PROJECT

MOHANPURA DAM PROJECT
A view of area available for construction activities
Sufficient working space for office, residential, workshops, contractor’s
establishment, can be made available as per prevailing government policy and norms in case a part of infrastructure establishment is decided to be kept at the dam site itself or in nearby town of
Zeerapur. Suitable establishment at appropriate places in the command area can also be established which
will be helpful for execution of irrigation canal system and its operation and maintenance at a later stage.
The present technical staff available with the water resource department and the contracting agencies
possesses sufficient knowledge and skill which is required for execution of such medium sized earthen dam,
spillway and irrigation network. The proposed construction of dam project will not involve and requires any
foreign aid, transfer of knowledge and skill and import of any goods or material. Therefore once the project
is cleared for construction with fulfillment of all necessary formalities and the required fund release is
assured the construction of project can be completed within the stipulated period of six years from the date
of start.

SOCIO ECONOMIC IMPACT
The entire area coming under the impact of proposed Mohanpura project is an agriculture activities predominant area, but the area is also rapidly growing as a industrial area also. The areas adjoining
to Kalisindh sub basin on left flank has witnessed rapid urbanization and industrialization near Shajapur, Maksi, Dewas, etc. But otherwise the rest of the area is a rural area mainly surviving on
agriculture only. The land holding are small to mini size and about 80% holding is less than 5 ha in size. By
and large about 20-30% of population in rural areas falls below poverty line. Nearly 10% of rural population
falls under the category of land less formers mainly surviving on the work being generated in Kharif and
Rabi crops in their areas. Less than 5% of the population at present is engaged in the industrial jobs and with
the moderate rate of industrialization this percentage will touch percentage of about 10%-15% in next 30
year. The area also supports a huge numbers of migratory industrial labours as well as agriculture sector
based laborers.

MOHANPURA DAM PROJECT
For the assessment of likely impact on socio- economic front by the proposed construction of
Mohanpura dam the entire area can be divided as area falling on left flank of dam and area falling on the right flank of the dam. Since the proposed site for Mohanpura dam is situated just 30km u/s of
Rajashthan state borders, as such the interest of d/s areas are not much significant in the case despite being the case of interstate river at least for M.P. The entire catchment area up to the dam site since lies in
the state of M.P. therefore also the state of Rajasthan cannot claim for any water quantum stored in the
Mohanpura dam as per the national policy and mutual agreed terms and conditions. The part of Rajgarh,Shajapur and Mandsaur districts on the left bank of the proposed dam can only be
provided irrigation facilities with this dam. The most crucial associated part is that a part of this
command is again situated at a high altitude which cannot be provided with a conventional flow
irrigation and the irrigation facilities to this draught prone area can only be provided by a lift
irrigation system from the proposed main canal.
As narrated in relevant Para of the report this area is also facing acute drinking water shortage and most
of the town in sub basin and on its periphery like Shajapur,Sarangpur,Pachhor,Rajgarh,Dewas,Maksi are
being provided drinking water once in three days or even once in a week. In worst years the drinking water
is being transported by railway tankers. Thus the execution of the project is a absolute necessity of meeting
out drinking water, industrial and irrigation requirement of the adjoining areas. The project on its completion
will provide following main benefits :-
About 75% of the area between FRL and LSL will be annually available for tank bed cultivation.
This land will be highly fertile and will not be requiring any irrigation for taking Rabi summer crop.
1) About 10% of the area situated on the periphery of the reservoir will be benefited by direct lifting of
water by the farmers. This area can roughly assessed as 1500-2000ha.
2) Increased ground water table will permit additional irrigation coverage in the command area. By a
rough approximation at least a 10% increased in ground water can be taken by way of
recharging of ground water table and subsequent increase in ground water level.
3) Generation of direct and indirect employment to laborers in the construction of dam and
canal system for a period of 5-6 years and for another 4-5 years in ayacut development programme.
The proposed construction will also provide increased labor requirement in agriculture sector in long
term.

4) Availability of water for NISTARI purposes throughout the year.
5) Availability of drinking water facilities to the villages situated on the periphery of the
reservoir.
6) Psyculture in the reservoir will promote high protein food supplement to large number of
population.
The d/s area falling under the command will receive comparatively more benefits
than the u/s side. The main areas of expected benefits will be as below:
a) About 125000 ha of CCA will be brought under assured irrigation.
b) Higher probability of taking summer crops /perennial crops resulting in high economic
returns.
c) Increased ground water table and availability will ensure increased crop production and higher
intensity of irrigation.
d) Extended drinking water facility to the villages and towns in the command area by increased
ground water resources.
e) Water availability for NISTARI purposes in command and adjoining areas.
f) Increased production of fodder resulting in increased milk and animal products
production.
g) Generation of direct and indirect employment to land less farmers in multiple activities of
agriculture.
h) Creation of employment to about 250-500 laborers on dam and canal construction activities for
a period of about 6 year.
i) Development of agriculture based industries in the command area like sugar, soyabean and
milk processing unit and food processing units etc.
The proposed construction besides above benefits will also result in numerous other fringe benefits
such as associated development of infrastructure facilities in terms of road construction, house building
activities construction of Krishi Upaj Mandi, opening of workshops etc. The creation of large man made
reservoir will automatically invite tourism and water sport activities as the lake is very near to the towns of
Shajapur,Dewas,Sarangpur etc. The construction of project will also result in effective flood control in the
Kalisindh sub basin as well as in Chambal basin. This will also be helpful in improving environmental &
ecological balance on u/s and d/s areas of catchments & command.

CHAPTER - 10
ENVIRONMENTAL AND ECOLOGICAL ASPECT
The proposed project is situated on the western part of the state which is already experiencing the oncoming of desert from the adjoining state of Rajasthan. The increasing pressure
of growing population and tendency of increasing agricultural production by way of using excessive ground water has added to this problem of recurring draught conditions and near desert conditions in the
region of Malwa. The inception of a major storage project will greatly help in combating these two factors of alarming ground water conditions and confinement of incoming desert from the state
of Rajasthan. It is beyond doubt a construction of a major storage reservoir project is always associated with environmental and ecological problems. These are complex in nature and their relative long term effect are to be anticipated while finalizing a multipurpose project. The situation is further
complex in the Malwa region where the existing forest cover is very meager and density of population is
comparatively much more as compared to the other parts of the state. The construction of a dam and creation
of a big reservoir behind it, the surrounding system is bound to change where the total gains are to be
evaluated against the expected losses. The development of water resources in India that too particularly for
rain fed river basins (where 90-95%of rain is concentrate in just 2.5 month) is invariable and without
creation of big storage reservoirs which are able to store about 9 months of drinking and irrigation
requirement, the overall sustainable of development of this region cannot be thought for.
The construction of dam and creation of reservoir for storage of water for non- monsoon 9 month
period affects cultivable and non cultivable land, flora and fauna, denudation of natural forest, water logging,
salinity and alkalinity, water table change, change in water quality, air, water and noise pollution etc. But it
simultaneously adds to some associative good effects also in terms of availability of drinking water for live
stock, availability of fodder, availability of required minimum water for psyculture, etc.
The most unfortunate part of the rain fed river basins in the Yamuna basin are, that they support large
population on their area and practically not too many sites are available which favors construction of dam
and reservoir on it without much disturbing natural system. Balancing ecology
MOHANPURA MAJOR PROJECT
171
MOHANPURA DAM PROJECT and environment without submerging cultivable land and displacement of population, flora and fauna construction and development of water sector project is impossible. They invariably require
acquisition of land and property and ultimately the resettlement in surrounding catchment area. Thus the construction of Major River project with least disturbance to environmental and natural ecological
system should only be the theme for taking up of new multipurpose river projects. The river projects and particularly the Mohanpura project is thus so planned that it allows self resilience and adjustment in its surrounding to create a stable ecological system in the basin on all the three fronts
related to physical, biological and human areas of activity. The project construction will also involve a small
submergence of area of less than 100ha in the reservoir. This area being a attached part to the major forest
area and pockets (which will remain outside of submergence) will allow in maintaining ecological balance
and will be helpful in self migration of wild life to the adjoining areas.
As narrated in the report the construction of proposed dam and its canal system will involve very
meager submergence of forestland and forest area, as such the most important part of disturbance to natural
flora and fauna will be negligible. It is the human part that is going to be adversely affected by the
construction of dam and reservoir in terms of submergence of cultivable and non-cultivable land along with
the properties and other assets. This loan factor was given highest important in planning of this project .The
principle levels i.e. FRL & MWL has been so fixed so as to have lowest submergence under normal
reservoir operation and maximum flood conditions.
The construction of proposed dam and reservoir besides creating number of other small problems
like epidemic, change of water quality, water logging in the command area will also simultaneously have a
beneficial role in maintaining natural ecological balance in the river basin. The river Kalisindh is not a
perennial river from its origin to the dam site. The river goes dry by around Jan/Mar in each year creating
numerous problem and disturbance in the surrounding area. The construction of this dam will charge the
river from dam to its confluence point where it meets with river Chambal for full year. A provision of
5Mcum of water in the Mohanpura reservoir is additionally made in the water planning which will be
regulated in the river solely for this purpose. This will greatly help in maintaining ecological balance in the
river. If the

The soil survey of the topography of command area, slopes in the basin, the expected trend of
cropping pattern associated with the very poor ground water availability simply eliminates the likely chance
of water logging in the command area. The height of storage will also not encouraged algae growth and there
is no danger of major change in quality of water in the situation .

AGRICULTURE AND IRRIGATION PLANNING
Description of command area :
The Mohanpura major project aims at utilizing the water
of Kalisindh river for
providing irrigation facilities to a cultivable area of about 125000 ha. The irrigation facilities provided by the project shall boost the agriculture production as well as in growing improved
varieties of the crops in the area that will alleviate economic status of the people.

irrigation, meaning that more cultivable land can be brought under production. This is the basis
upon which the planned CCA of Mohanpura mojar project was increased from 58040ha to
125000ha.
The on- farm irrigation efficiency of a properly designed and managed micro irrigation
system (i.e ,drip or micro spray)can be up to 80 -90%, while for well managed sprinkler system the
efficiency may be uo to 70-80% which are both significantly higher than traditional surface
irrigation methods .
Effect on cost of B-land in unit 2
Due to change in irrigation system gravity to pressurized irrigation system
CCA increased form 58040ha to 125000ha and cost of B-land in unit 2 has also decreased because
in gravity irrigation system permanent land acquisition is required but in pressurized irrigation
system small area for pump houses required permanent land acquisition and rest temporary land
acquisition is required for running the pipeline system.
