Purpose of the Draft PlanPurpose of the Draft Plan

To present the situation in local level (Axios river area) for

the possibility to develop plans.

Additionally, it will help the certificate body and also the

investors to evaluate the possibility to create a SHP in

certain positions.

Contents of the proposed Draft PlanContents of the proposed Draft Plan

The plan should combine:

General information for the pilot spatial development in the

area.

Limitations which arise in the area and how they affect the

proposed Plan.

Probable locations of SH projects from a technical point of

view.


Sources for the plan contentsSources for the plan contents

Public Authorities (RCM, Municipalities, CRES etc.).

Recent Studies for the area.

Acquisition and elaboration of technical data (maps, rivers flow, networks etc).

Site visits.

Feedback from publicity actions.


The Area:The Area: AxiosAxios River River MAIN CHARACTERISTICS:

380 km2 length - 23.747 km² total extent90,2% belongs to the F.Y.R.O.M. and 9,8% to Greece701 km2 is the interested areaWidth: 50-600 mDepth: up to 4 mAnaglyph of the area: smooth

LIMITATIONS:Protected Areas:

- Axios Delta (an area of 100 hectares in the river’s mouth) is protected by RamsarConvention

- An area of approximately 60 km to the borders is belong to Natura 2000 sitesHuman activities:

- Fishery- Agriculture- Stock farming- Extraction (sand, water)

All these elements will be established in GIS form


Facts and problems in the case ofFacts and problems in the case of AxiosAxios RiverRiver

Spatial planning in a Regional level is a concept in its first steps. The existing spatial planning doesn’t include the use of the river for hydro plants.

Lack of management plan for river basins. It exists only for the Ramsarterritory.

Lack of interest from the local Authorities.

Lack of hydrologic and hydraulic data. The cost to buy any existing data is very high.


Methodology to develop SHP projectsMethodology to develop SHP projects

The project consists of a G.I.S. based application that holds all the necessary information of the specific area of interest in the form of information layers on a base map.

MULTICRITERIA ANALYSIS GEOGRAPHIC INFORMATION SYSTEMG.I.S.

These layers will clearly designate the state of the specific area as far as terrain model, topography, hydrology, background, habitation, and particular ecosystem are concerned.

SUITABLE LOCATIONSSUITABLE LOCATIONSThe particular two Small Hydro Project sites are located in the west and east main irrigation channels of the Ellis Dam in river Axios. These channels serve the irrigation needs of the surrounding areas. The water supply is possible through a type S (ogee) spillway. The two channels have very similar geometry and the available design flow in both of them is about 1/3 of the total flow of Axios river. Finally, the gross pressure head is estimated to be about 12m.

For the assessment of the SHP feasibility, the “RETScreen Small Hydro Project Model” was used to evaluate the energy production, life-cycle costs and greenhouse gas emissions reduction for the two similar central-grid single-turbine, small hydro projects.
