3. Legal and Institutional Framework on Flood Risk Management inEurope:theEUFloodsDirective
This section gives an introduction to EU Floods Directive and describes its aim and main steps ofimplementation.TheoverviewoflegalframeworkofFloodRiskManagementinPPRDEast2sixpartnercountriesisalsoprovidedbasedonlastupdated(2015)CountryProfilereports.
3.1 MainRequirementsofEUFloodsDirectiveTheEuropeanFloodsDirective(EUFD)hasaimto7:
− establish a framework for the assessment and management of flood risks, aiming at thereduction of the adverse consequences for human health, the environment, cultural heritageandeconomicactivityassociatedwithfloodsintheCommunity;
− establishaprocessforproducingfloodhazardmapsandfloodriskmapsinordertoaddressthefloodrisk;
− in the flood riskmanagementplansaddressall aspectsof flood riskmanagement focusingonprevention,protection,preparedness, includingfloodforecastsandearlywarningsystemsandtakingintoaccountthecharacteristicsoftheparticularriverbasinorsub-basin.
TheapproachtofloodriskmanagementinEUMemberStatesisdividedinthreemainsteps,asfollows8:
1. EU Member States undertake a preliminary flood risk assessment of their river basins andassociatedcoastalzones,toidentifyareaswherepotentialsignificantfloodriskexists-by2011.
2. Whererealrisksofflooddamageexist,floodhazardmapsandfloodriskmaps forsuchareasmustbedeveloped-by2013.Thesemapsidentifyareaswithamediumlikelyhoodofflooding(atleasta1in100yearevent)andextremeeventsorlowlikelihoodevents,inwhichexpectedwaterdepthsareindicated. In the areas identified as being at risk the number of inhabitants potentially at risk, theeconomicactivityandtheenvironmentaldamagepotentialareindicated.
3. Finally,floodriskmanagementplansmustbedrawnupforthesezones-by2015.Theseplansaretoincludemeasurestoreducetheprobabilityoffloodinganditspotentialconsequences.Theywilladdress all phases of the flood risk management cycle but focus particularly on prevention (i.e.preventingdamagecausedbyfloodsbyavoidingconstructionofhousesand industries inpresentandfuture flood-prone areas or by adapting future developments to the risk of flooding), protection (bytakingmeasurestoreducethelikelihoodoffloodsand/ortheimpactoffloodsinaspecificlocationsuchas restoring floodplainsandwetlands) andpreparedness (e.g.providing instructions to thepubliconwhat todo in theeventof flooding).Duetothenatureof flooding,muchflexibilityonobjectivesandmeasuresarelefttotheMemberStatesinviewofsubsidiary.

The EU Floods Directive indicates that Member States may make use of the administrativearrangementsmadeunderArticle3oftheWaterFrameworkDirective.However,differentcompetentauthoritiesmaybeappointedbyMemberStatesfortheFloodsDirective.
RiverBasinDistrictsAs defined by the European Commission, "River Basin Districts (RBDs) are the main units for themanagementofriverbasinsandhavebeendelineatedbyMemberStatesunderArticle3oftheWaterFrameworkDirective(WFD).FortheFloodsDirectiveMemberStatesweregiventhechoicetouseeithertheWFDRiverBasinDistricts,ortodesignateotherUnitsofManagement(UoM)forspecificriverbasins

or stretches of coastal areas under article 3 of that Directive. For themajority of RBDs, EUMemberStates used the same ones as for theWFD. The geographic area of some RBDs spanmore than onecountry (such as the Danube) and these are known as International RBDs. Others (theminority) arecontainedcompletelywithinacountryandareknownasNationalRBDs."UnitsofManagementTheUoMconsist inboundariesidentifiedtomanageriversand/orcertaincoastalareas.ThedefinitionoftheUoMcanbebasedongeomorphologicaloradministrativecriteria.ObjectasdefinedintheEUFD:Maybe individualriverbasinsand/orcertaincoastalareas;maybeentirelywithinnationalbordersormaybepartofaninternationalUnitofManagementorInternationalRiverBasinDistrict.TheFloodsDirective(Article3.2)allowsMemberStatestoidentifyUnitsofManagementdifferentfromthe River Basin Districts used for the Water Framework Directive. Competent Authorities will berequiredforeachnationalRBDorUoMandfortheportionofanyinternationalRBDorUoMlyingwithinitsterritory.The EUFD implementation process needs to start from a complete definition of the command andcontrolchainforFloodManagement;mappingofinstitutionscompetentinalltheaspectsofEUFDandunderstandingpotentialconflictswithotherEUDirectives/Nationalplansisapriorityandthefollowingaspectshavetobeanalyzed:

Theanalysisshouldbeabletodefinetheframeworkinsidewhichitisclearlypossibletoidentifywho:• isinchargeforcoordinatingthePFRA;• hasthetechnicalknowledgeformanagingPFRAdataeventuallyavailable;• hastheinformationatlocal/catchmentlevel.
In theory, the institutions involved in the PFRA can be various, and an appropriate coordination andharmonization of their activities should be done, eventually developing a capacity building phasespecificallyorientedtothistask.Only afterwards can properly start the implementation of the operational procedures aimed topreliminaryassessareaswithpotentialsignificantfloodriskandtodevelopachainofstudiesuponthemwhichwillbeconcludedwiththeproductionofproperoperativefloodmanagementplans.It has to be underlined that EUFD recommend to widen the analysis with the updated overview ofongoingorcompletedrelevantinitiativesregardingthelocalapproximationtoEUFD,withattentiontobepaidonpossiblesynergies.ObjectasdefinedintheEUFD:Preamble,point17:DevelopmentofriverbasinmanagementplansunderDirective2000/60/ECandofflood riskmanagementplansunder thisDirectiveareelementsof integrated riverbasinmanagement.

GeneralDescription
TheEUFDwastransposedintoGermannationallawbymeansoftheFederalWaterAct(WHG)of31July2009(FederalLawGazetteBGBlIp.2585).TheActenteredintoforceon1March2010.Thestandardbasis for conducting thepreliminaryassessment inGermany is the recommendation forthe “Approach to be used in the preliminary assessment of flood risk under the European FloodsDirective 2007/60/EC” developed by LAWA (GermanWorking Group of the Federal States onWaterIssues–Bund/LänderArbeitsgemeinschaftWasser).
Methodology
Accordingtothe2007/60/EC,criteriaforhumanhealth,fortheenvironment,forculturalheritageandfor economic activities are mentioned and detailed. Other criteria are mentioned comprising thenumber of affected inhabitants, number of affected buildings, expectedmonetary damage (in Euro),inundation depth and flow velocity, significant infrastructure, already realised precaution measuresagainstfloods,existingprecautionmeasuresanddamagepreventedbythosemeasures.TheLAWA“RecommendationsfortheEstablishmentofFloodRiskManagementPlans”of2010aimistoensurethatthecontentanddesignofthemapsarestandardisedasfaraspossible,thusensuringthatthesetofmapsproducedhasnationwidecoherence.ThedeadlineforPFRAactioninGermanyinordertoidentifytheareas/waterbodiesforwhichpotentialsignificantfloodrisksexistwasendof2011.When making the preliminary assessment of flood risk, factors such as experiences from historicalevents,foreseenimpactsofclimatechangeandforeseensocialconsequencesfromafloodingshouldbetakenintoconsideration.The preliminary assessment of flood risk based on Art. 2 (2) of the EU Floods Directive provides theinformation on areas with present or future potential significant risks of flooding. The assessmentsconsider all potential sources of flooding such as from rivers, lakes, coastalwaters, groundwater andsurfacewaterfloodingfromheavyrainfall.Artificialstructuresholdingwater,suchasdams,reservoirsand canals, also representapotential significant sourceof flooding,particularly if therewere tobeacatastrophicfailureofthestructure.Theexistinganalysesoftheadverseconsequencesoffloodsthathaveoccurredinthepastshowclearlythatsignificantfloodrisksariseonlyfromregionalorsupraregionalfloodswithprobabilityofoccurrencehigherthanaverage(HQ100)inaverage-to-denselypopulatedareas.Thesefloodsarecausedbysurfacewaters.

Methodology
ThreekeyapproacheshavebeenusedinundertakingthePFRAtoidentifytheAFAs:−HistoricFloodRiskAssessment:informationonfloodsthathavehappenedinthepast.
o NaturalSourcesofFloodRisko Floodsfrominfrastructurefailure
− Predictive Analysis is an assessment of areas that could be prone to flooding, as determined bypredictivetechniquessuchasmodelling,analysisorothercalculations,andofthepotentialdamagethatcould be caused by such flooding. The flood risk is a function, or combination, of the hazard andconsequences.TheGiventhelackofavailableinformationonpastfloodextents,andthebroaderneedfor flood maps with a national coverage Office of Public Works (OPW) has determined predictiveassessmentsuitableforIreland.− Consultation: use of local and expert knowledge of the Local Authorities and other Governmentdepartmentsandagenciestoidentifyareaspronetofloodingandthepotentialconsequencesthatcouldarise. Other EU Member States have used similar approaches to undertaking the PFRA as thatundertakeninIreland.The PFRA is not a detailed assessment of flood risk. It is rather a broad-scale assessment ofcommunities,facilitiesandsiteswheretheriskduetofloodingmightpotentiallybesignificant.TheAFAsaresubjectedtomoredetailedassessmentsandanalysisbyCFRAMandparallelstudies.ThePFRAconsidersfloodriskarisingfromanymajorsourceofflooding,including:NaturalSources:

ARMENIA
During PPRD East Phase 1, Institute of Geological Sciences - ArmenianNational Academy of Sciences(NAS IGS) was in charge for computing flood hazard and flood risk maps. A sort of preliminary riskassessment has been undertaken by analysing the MTAES database on floods. By doing that, muchinformationabout theeventhasbeendigitalized;nevertheless this analysisdidnot lead todefinitionandmappingofareasofpotentiallysignificantfloodrisk(APSFR).

5.4 GuidanceandMethodologiesforPreliminaryFloodRiskAssessment
Implementing the EUFD is made possible through the establishment of more or less detailed dataarchives connected to all the information sources that are relevant to the fulfillment ofmore or lessdetailedstudiesfortheapproximationofeachstepprovidedforbyDirective.
DataManagement
For this reason all aspects in finding the information, analyze it, process it to produce themaps andpublishtheresults inthemannerprescribedbyEUFD,shouldbethesubjectofacriticalplanningandtargetedtocreateaneffectivesubsetwhoseelaborationwillidentifythefloodriskareasandwhateverconnectedatleastwithapproximatemethods,orifpossiblewithmoredetailedstudies.
Inpresentingthegeneralframeworkofstudiestobedescribedinthefollowingchapters,itisusefultoconsiderthattherearesomecommonpointsinthevariousarticlesoftheEUFD.Ingeneralitisneededtoperformstudiesthatarisewiththecollectionoffloodeventsinthepasttogettopredictivemapping,andcalculationsstartfromconsiderationsevenverysimplifiedtoarrivetodetaileddescriptionswiththe

evolutionofthestudies.ItstartsfromtheidentificationofAreasofPotentialSignificantFloodRisk,thatarethespatialobjectsonwhichallsubsequentstudiesareimplanted.Theseelementsinthetruthcanbe representedwithdifferentgeometry types: criticalpoints, in the caseofmethodsof identificationbasedonlyon the simple localizationof coordinatesofpreviousevents; areaswithadominant lineardistribution, where the studies are linked to critical sections of waterways; areas with variabledistribution,inthecasetheanalysesarebasedonadministrativeunitsorcomparedtoareasofvariableamplitudearoundthesitesofpastevents.
However, on these critical and strategic areas, it is necessary to provide the construction ofmultiplehazardandriskscenarios,eachcharacterizedbyspecificconsequences thatcannotbeseparatedbyascreening of the possible receptors of risk. The criteria for differentiation of risk receptors must bebrought back to the classesHuman health, Environment, Cultural heritage, Economic activity, or in amore conciseway, Social, Environmental, Cultural, Economical Themethods for assigningaweight tothese receptors and assigning a value to their physical and possibly systemic vulnerabilities arecharacteristicofeachareaandawell-structuredapproachtothestudycannotignoretheneedofmanypassagesofmodelingandback-analysisaimed to identify themostappropriatevalues for the systemyouareanalyzing.Theabsenceofthesecriticalfiltersmayoccurinextremecasesinwhich,startingfromhistorical events of the past, the whole territory remains affected under investigation for theconstruction of future risk scenarios and all the affected areas have the same value for planningpurposes,oronthecontrary,onlyaverysmallportionofthecountryistakenintoaccount.
So,indraftingageneralschemeforthecollectionofdatanecessarytotheimplementationofEUFD,ithastobeconsideredthat,beyondthehistoricinformationonpastfloodevents,whateverusefultothedescription of the territory and of the Social, Economic, Environmental, Cultural receptors could beused.Atleastacoredatasetofminimumgeospatialelementsisneeded:
• adescriptionoftherivernetwork
• adescriptionofthelanduse
• thedistributionofpopulation
This is an oversimplification, and certainly it is advisable, if possible, to have other additionalinformation on population, objects of significance, areas and activities that could suffer harm in theeventofafloods.
In this case it ispossible todefine the so-called IndividualReceptors18 (e.g.Hospitals,PowerStations,Airports,Schools),ArealReceptors(e.g.Cities,Villages,EnvironmentalSites),Social Infrastructure(e.g.Emergency Response Centres, Evacuation Centres), Critical Utilities (e.g. Water Supply & Treatment,Electricity,Communications)orevenspecificclassesofpopulation(e.gVulnerablePeople-Elderly,VeryYoung)
Considering the needs for a proper application of models, of extreme importance are also: DigitalElevationModels (DEM), topographicmaps,hydrologicaldata,hydraulic structuresandmapsof floodextentofthepast.
A specific attention should be paid to the scale of data and their compliancy with the scale of thestudies;moreover, itmust be checked for topological correctness and compliancy with internationalstandards.Aboutthispoint,theEUFDrecommendstheassessmentofpotentialriskbasedonavailable

At this stage a simplified methodology should be used in order to define the method (or thecombination of methods) for flood prone areas identification with the aim to enable theclassificationandprioritizationofareasconsideringtheadverseconsequencesofflooding.Thesemethodsinclude:A. Geological approach, based on geological maps. In this hydro-geomorphological mapping
method river beds are studied using topographic information (orthophotos, Digital ElevationModel-DEM)andgeologicalinformation.
B. GISapproaches,wereportinthefollowingtwoexamples:• "Waterlevelrise"methodthatisbasedontheprincipleofrisingthewaterlevelintheriverbed.

RiskIdentification
ByPPRDEAST1Risk/HazardAssessmentPolicy is proposed theuseof the riskmatrix during the riskidentificationstageforfurtherdevelopingofunderstandingoftherisksandtheimpacttheypresentataregional and national level. The use of the risk matrix tool also allows comparison of different risksituations quantitatively by considering the various ensuring consistency to assessing the impact andprobabilityofanevent.Whereadditional risk investigationsmeasureshavebeen identified through the riskmatrix approach,specific hazard, vulnerability and exposure analysis can be undertaken. These methods are alsodocumentwithintheriskanalysissectionofthispolicy.Attheriskidentificationstageitisimportanttoconsider all hazards, how they interact, their probability of occurrence and their possible impact.Analysis on this scale is referred to as considering “risk scenarios”. Risk scenarios are a plausibledescriptionofhowthefuturemaydevelop.Scenariobuildingismainlybasedonexperiencefrompastevents, risk matrixes can be used to develop the scenarios when considering the different plausibleoutcomes.

1. Type of floods to be considered - Floods can have various origins depending on thecharacteristicsofthebasinsandmeteorologicalregime.Adecisionhastobetakenwhichtypesoffloodsshouldbeconsidered.Theoriginoffloodscanbeverydifferent,e.g.floodingfromthesea, flashfloods,groundwaterflooding.Considerwhetherfloodingfromtheseamightcreateserious risks and if so, checkwhether collected data are sufficient. The same holds for areaswhereflashfloodsorfloodsfromgroundwateroccurinamorethanaccidentalway.
2. Typeofinformationneededforthehazard/riskmaps–ThischoicedependsontheoperationaluseofFHMandFRM.ExampleofinformationneededinthefullcycleofDisasterManagement:prevention/mitigation,preparedness,responseandrecovery

FiveMember States alsomapped flow velocity or relevantwater flow for atleastoneofthethreeprobabilityscenarios.
Resolutionofmaps
26 Member States had maps that had a scale of 1:25,000 or larger, indicating that they should beappropriate for public use. Themaps for Hungary had a scale of 1 to 2,000,000 which seems to beinappropriate for public information and awareness purposes. Therewas no information for Bulgariawhichhasyettoreport.

Methodology
Inorder tocomplywith theprovisionsof theFRMDby thedeadlines specified, it is recommended to
assign to each Germany’s federal states (Länder) a lead agency with responsibility for preparing the
FloodHazardandFloodRiskMapsandinitiatingsuchpreparationinatimelymanner.
TheFloodHazardandFloodRiskMapsandpossibleconclusionstobedrawnfromthemwillthenalso

TheFloodHazardMapsdepictthescenariosthatcouldoccurundercurrentconditions.Theuseofup-
to-date hydrological data means that climate change impacts which have already occurred are
incorporated into themaps. Future trends, as far as they canbepredicted, canbe considered in the
FloodRiskManagementPlans.
FloodRiskMapsarepreparedforthesamefloodscenariosonthebasisoftheFloodHazardMaps.They
should show, based on the flood hazards maps (extent of flooding), the adverse consequences of
flooding.

• the inclusion of sites of particular cultural relevance in the FRM is not a requirement of the
FRMD.
ThefollowingrecommendationsareintendedtofacilitatethestandardizeddesignoftheFHMandFRM
throughout Germany and should be followed unless the federal states (Länder) apply different
procedures.
1. Dataprocessingandmapstructure–GISshouldbeusedtocollect,customizeandupdatebasic

ItalyFloodHazardandRiskAssessment
GeneralDescription
TheMinistry of Environment, Land and Sea Protection (MATTM) informed the European Commission
that Italy would made use of the transitional measures, as required by the art. 13.1b of Directive
2007/60/EC, and therefore would not carry out the preliminary flood risk assessment referred to in
Article 4, having decided, before 22 December 2010, to draw up hazard and flood risk maps and
establish management plans for flood risk in accordance with the relevant provisions of the Floods
Directive.
Thisdoesnotexcludetheneedtoprove,uponrequestoftheEuropeanCommission,thatallthesteps
requiredbyart.4oftheFloodsDirective,havebeenconsideredintheidentificationofareasatpotential

Methodology
The Legislative Decree no. 49/2010 state that the flood hazardmaps and flood riskmaps, should be

FloodHazardMapping
The reporting of hazardmaps, according to EU Floods Directive 2007/60/CE, is based on a series of
textual information andon geographic information (e.g. shape files andpolygonsof the flood areas).
Text informationforthereportingoffloodmapstobeprovidedbyXMLfilesorACCESStables,whose
contentsandrelationshipsaredefined.TheyconsistinaseriesofSUMMARYTEXTs,inthedescriptionof
the type of floods and possibly of the features and mechanisms associated with them and in the

Thesummaryinformationincludes:
61
• theextensionofflood(includingtheresolutionofdigitalmodels);
• thelikelihoodoffloodingorreturnperiod;
• heightorwaterlevels;
• speedand/orflowrates(whereappropriate);
The geographic information is represented by polygon type and with an extension of the flood
associated to each flood scenario (high,medium, low likelihoodof flooding). The informationof XML

Embankments
The methodology recommends to include the embankments in hazard management plans and to
provide a value of security in respect of occurrence of frequency of breaks of embankments of II

In Armenia Flood Hazard and Flood Riskmapping have been both carried out during last few years,nevertheless theapproximation level toEUFD isstillquite low.The floodhazardmappingbyNationalAcademy of Sciences, Institute of Geological Science (NAS IGS) is not compliant with the detail levelrequiredbyEUFDandhavenodirectlyrelationtoreturnperiods(i.e.,probabilityofoccurrence),whichisoneofthemainpointsofEUFD.
DuringPPRDEastProgrammePhase1theNASIGShasdevelopedanation-widemappingofthefloodhazard.OtherprojectsrelevanttothetopicistheGermanTechnicalCooperationAgency(GTZ)fundedprogramme“DisasterPreparednessinSouthCaucasus”thatfocusedonLoriandTavushmarzesinwhichNASIGSwasoneoftheimplementerand“ModelGuidelinesForWaterBasinManagementPlanningInArmenia” for the Meghriget River funded by United States Agency for International Development(USAID)(incollaborationwiththeWaterResourcesManagementAgency(WRMA)undertheMinistryofNatureProtection).
Currently, are developing the 6 water basinmanagement plans. The Government of the Republic ofArmenia, inFebruary2011,approvedthecontentoftheWaterBasinManagementModelPlan,whichhasbeendevelopedwithintheframeworkoftheEUWaterinitiative–accordingtotherequirementsoftheEUWaterframeworkdirectiveandWaterCode.Atpresent,thecontentofthemodelplanisalegaldocumentanditisatechnicalassignmentforthedevelopmentofArmenia’sWaterBasinManagementPlans.The3rdand4thchaptersof theWaterBasinManagementModelPlancontain to theemergencyandpreventionmeasures;themeasuresmustbeimplementedwithin6yearsafterthefinalapprovaloftheplansbythegovernment.Currently, in Armenia there are several activities related to the development of a Water BasinManagementPlan:
• Arpa river developed during UNDP - Global Environment Facility Reducing Trans-boundaryDegradationintheKura-AraksRiverBasinProject27
• Akhuryan river under the EU funded project “Environmental Protection of International RiverBasins”(EPIRB28).TheplanwillbesubmittedtotheMinistryofNatureProtectionin2016.
• Model guidelines for water basin management planning in Armenia - Meghriget riverimplementation,fundedbyUSAID.
According to the requirements of the Government protocol decree N4 dated 03.02.2011, the SouthWaterBasinManagementPlandevelopedwithintheframeworkoftheUSAIDCleanEnergyandWaterProgram and the “Ararat valley water basin management plan” developed by the "Armhydroenergoproject" CJSC (the state budget funding) have been submitted to theMinistry of Nature Protection,which in 2016 will be submitted to the Republic of Armenia Government for approval. The WaterResourceManagementAgencyunder theMNP is thenational focal reference for them.Even if theseinitiativesaremuchmoreorientedtotheWaterFrameworkDirectivethanEUFD, itseemstoustoberelevant to cite them as Water Basin Management Plans should include emergency plans (watermanagement during emergencies) anddisaster recovery plans.Moreover, regardless of the fact that,generallyspeaking,thefloodriskisnotassessed,aregisterofhistoricalfloodsissetupveryoftenandacensusofnaturalandartificialwaterbodiesarereportedaswell.Forinstance,afullcharacterizationoftheMeghriget River Basinwas completed in theUSAID project and published as Synthesis Report of27(UNDP/GEFKuraAraksProjectatlinkhttp://www.kura-aras.org)28(ENPI-EPIRBprojectatlinkhttp://blacksea-riverbasins.net/en)

6.4 GuidanceandMethodologiesforFloodHazardandRiskAssessment
ThePPRDEast1 study includes in theRiskAssessmentProcess threecomponents:Risk identification,RiskanalysisandRiskevaluation.Risk Identification - identifying sources of risk, areas of impact, events and their causes and theirpotentialconsequences.RiskAnalysis -developinganunderstandingoftheriskthroughspecifichazard,vulnerabilityandassetassessments.
73
Risk Evaluation - evaluation of the risk analysis process is undertaken to assess which risks warrantgreater consideration, this allows for a priority list for treatment strategy implementation to bedeveloped.Accordingly toPPRDEast1Risk/HazardAssessmentPolicy29,anAsset characterizationprocess shouldbe conducted in two stages, in order to make the process efficient.

Currently there areno FRMPsoperating in the country and there is a need to identify structural andnon-structuralmeasuresforfloodriskreductionandmitigationaccordingtotheindicationoftheEUFD.FRMPsneedtobeintegratedwithRBMPsand,specifically,withtheonesalreadydevelopedforDniesterand Prut rivers and some sub-basins. FRMPs need also to include an early warning system and tointegratelocal,territorialandstatedisasterandcivilprotectionplans.It is recommendedtodevelopFRMPs forall theUnitsofManagementof thecountryandto integratethemwith the RBMPs as required by bothWFD and EUFD. It is further recommended to establish acontrol mechanism to periodically check-up the effective development and implementation of theFRMPs.

River basin management plans have not been formulated conclusively. Measures are much morefocused on water quality and water supply for different use. It is noteworthy to recall that EUFD-compliantfloodriskmanagementplansalsoconsistofaneffectiveEarlyWarningSystem.Ukrainehasalready in place an effective system forweather and flood forecasting (managed by the UHMC) andresponse(SES).For a further development of thewhole system it is recommended to include flood riskmanagementprinciplesinlinewithEUFDintotheriverbasinmanagementplansandtoimprovetheefficiencyoftheobservational network by modernizing, reequipping technically and technologically, increasing thenumberofandfurtherdevelopingautomatedstationsengagedinmeasuringwaterlevels,rainfalletc.

TheWMOGuide for Integrated FloodManagement31 provides the contents and basic procedures ofbasinfloodmanagementplanning.ThisGuiderepresentsanadditionalsourceofinformationonFRMPdevelopment.Several fundamental issuesrelatedtothefloodmanagementplanning,suchasnationaldevelopmentof vision/policy and enablingmechanismof floodmanagement planning, are explained.The flood management policy should be closely aligned to the water resources development andmanagementanddesignedseparatelyfromdisastermanagementpolicies.
The “Integrated FloodManagement” (IFM)means harmonization of human behavior in relationwithriverregime.InthisrelationtheevaluationofbeneficialfunctionoffloodsandnegativeconsequencesoffloodrisksisthefirststepindevelopingofaFloodManagementPlan.
AccordingtoWMOrecommendationstheBasinFloodManagementplanningshouldreflecttheoverallvisionandpolicyofIntegratedWaterResourcesManagement(IWRM)withparticularattentiononthemanagement of floods. IWRM approach has been accepted internationally as the way forward forefficient, equitable and sustainable development and management of the world's limited waterresources and for coping with conflicting demands. The basic cycle for developing an IWRM plan asgiveninFigure5.

8. Conclusions
The guidelines are developed on the base of EU Floods Directive 2007/60/EC, Good Practices of EUMember States on PFRAs and FHRM development, the European Overview Report on PFRAs, theEuropeanOverviewReport on FHRMs, PPRDEast1Risk/HazardAssessmentPolicy andWMOTool forIntegratedFloodManagement.EUFloodsDirective2007/60/ECThisdocumentprovidesanintroductiontoEUFloodsDirective2007/60/ECandgeneralexplanationondevelopmentoffloodriskmanagementapproachtoreducetheprobabilityoffloodinganditspotentialconsequences.Thethreemainstepsaredefined:
- PreliminaryFloodRiskAssessment;- FloodHazardandRiskMapping;- FloodRiskManagementPlan;
TheEUFDimplementationprocessisrecommendedtostartfromacompletedefinitionofstakeholdersandskills.Afterwards the implementationof thePFRAPhase1operationalproceduresonpreliminaryassessment of areas with potential significant flood risk is begun. The basic data collectionrecommendedbyEUFDshouldinclude:
- historicinformationonpastfloodevents;- Social,Economic,Environmental,Culturalreceptors;- descriptionofminimumgeospatialelements:rivernetwork,landuse,distributionofpopulation.
PFRAPhase2 isapreliminaryfloodriskevaluationthroughcombiningthebasicdataobtainedinPFRAPhase1toproduce:
• Preliminaryfloodhazards(from:Historicalfloods/floodableareas+spatialbuffer);• Preliminary flood risk (from: Preliminary flood hazards + Population density maps + Other

- Typeoffloodstobeconsidered;- Typeofinformationneededforthehazard/riskmaps;- Kindofhazardandriskmapsproduced.
The risk maps should include elements under risk such as: people, economic activities, andindustries/installations in the potential inundated areas. Flood Hazard Maps (FHM) scenarios andelements formodelingaredefined insub-section4.2.FloodRiskMapsaredevelopingon thebasisoftheFHMforthesamescenarios.FloodriskmanagementplansasdefinedinEUFDshouldfocusonprevention,protection,preparedness,including flood forecastsandearlywarning systemsand taking intoaccount thecharacteristicsof theparticular river basin or sub-basin. The stages of Flood RiskManagement Cycle are provided in sub-section5.1.

WMOFloodRiskManagementPlanTheWMOapproachonFloodRiskManagementPlan(insub-section5.3)providesfurtherexplanations,on basic procedures for basin floodmanagement planning development and serves as an additionalWMO established information on Flood Risk Management Plan development. The principal steps ofWMOFloodManagementPlandesigninclude:
− The planning process: stakeholders, public awareness, steering committee, task team,coordinatingbody;
− DataSurveyandAnalysisonBasinconditionandSocialandeconomiccondition;− Assignmentofindicatorsandthresholdvaluesforvariouslevelofmanagement;− Setting target for basin flood management plan: how the flood risks would be reduced or
managed;− Identification and selection of options to reduce risks: reducing of hazard, exposure and
vulnerability;− ImplementationPlanandMonitoring:organisationofparticipatoryprocess,assignmentof the
roles and responsibilities, timelines definition, resources assessment, drawing of alternativeapproaches.
WMO “Formulating a Basin Flood Management Plan” recommends associate a Basin FloodManagementPlanningwithanIntegratedWaterResourcesManagementplan.TheessentialconcernbyWMO ismonitoring of basin condition before, during and after the implementation of the plan. ThenecessarystepsshouldassistinsuccessfulimplementationofFloodManagementPlanatbasinlevel.PPRDEAST1Risk/HazardAssessmentPolicyThe PPRD East1 Assessment Policy provides fundamental concepts of Risk Management Processcompliantwith EUFD, in particular for PFRA. The hazard riskmanagement chain is divided intomaincomponents:Establishthecontext;Identification;Analysis;EvaluationandTreatRisks.The first is toestablishacontextanddefine riskcriteria,externaland internalparameters, scopeandobjectives for entire Risk Management Process. After that begun Risk Assessment Process includingthreeaspects:Riskidentification,RiskanalysisandRiskevaluation.RiskTreatmentconsistsinselectionand implementation of themost appropriate risk treatment options. Continuous communication andconsultation process ensure precise and proper exchange of information during Risk Management.MonitoringandReviewshouldbemaintainedduringwholeprocessofmanagement to insureefficientoperationofmanagementchain.
CurrentStatusofFloodRiskManagementinEaPCountriesAs NAGmeetings (2015) demonstrated, that the Flood Risk Management plans in partner countriesgenerally demonstrate lack of readiness.Usually the flood riskmanagement principles are developedonly at local level/partially and need to be brought in line with EUFD. The observational networkfrequently is insufficient. The definite legislation and clear responsibility for development,implementation and update of the plans should be designed. Among themain recommendations onFloodRiskManagementprocessdevelopment,providedinCountryprofilestopartnercountries,are:
- updateofthecurrentlegislationonRBMPs- includefloodriskmanagementprinciplesinlinewithEUFD- developFRMPsforalltheUnitsofManagement- improvetheefficiencyoftheobservationalnetwork

10. Annex1–TypesofFloods
The EU Floods Directive 2007/60/EC covers all kind of floods: river, lakes, flash floods, urban floods,coastalfloods,includingstormsurgesandtsunamisonalloftheEUterritory.Accordingto(Quevauviller,2014)belowarelistedfloodtypesthatshouldbeincludedinmodelling:
1. Riverine floods.
