2 PFRA report Introduction; Overall approach and methodology of PFRA; Historical floods in the Danube River Basin; Potential adverse consequences of future floods; APSFR (national/drbd); Addressing the impacts of climate change; Transboundary coordination & information exchange; Supporting transboundary activities; Conclusions.

3 PFRA data geometry types Polygon: Recommended for areas >= 100km² Line: Recommended for river stretches >= 50km. Point:Recommended for areas <100km² and river stretches <50km.

4 EFD Art 6 Member States shall, at the level of the river basin district, or unit of management referred to in EFD Article 3(2)(b), prepare flood hazard maps and flood risk maps, at the most appropriate scale for the areas identified under EFD Article 5(1); The preparation of flood hazard maps and flood risk maps for areas identified under EFD Article 5 which are shared with other Member States shall be subject to prior exchange of information between the Member States concerned.

5 ICPDR response The FP EG agreed that flood risk mapping under the ICPDR will be only done on the basin wide level (level A). The report to the EC will contain references/links to the outcomes of the relevant projects (Floodrisk) and to the activities carried out in sub-basins (e.g., ISRBC). The recommendations of the draft EU document "Reporting of spatial data for the Floods Directive (Part II); Guidance on reporting for flood risk and hazard maps of spatial information" were used by the FP EG for the first proposal of level A maps for DRBD.

6 Flood hazard and risk maps Countries were asked to provide draft data before FPEG- 23, information received only from AT, DE, BA, RO and SK; Working maps were prepared by the Secretariat and number of amendments was agreed by the FP EG; Flood hazard maps have to be submitted via DanubeGIS as shape files in cooperation with the IMGIS EG; The deadline for text contributions to the report to EC using the template prepared by the Secretariat is 1 August 2013.

7 Flood hazard and risk maps The national deadlines for map preparation reported by a number of countries would not enable preparing the final version of the ICPDR maps before OM16; It is suggested to present the draft maps containing all available information to OM16 to obtain a general agreement of the ICPDR and to upload then on the ICPDR website so that this link can be used in national reports; Collection of missing data will continue until March 2014 to prepare the final version for 12 th StWG meeting.

8 Flood hazard and risk maps The FP EG agreed about the content of the following maps: map of hazard and flooding scenarios; map on risk and population; map on risk and economic activity; map on risk and IPPC installations; two maps on WFD protected areas.

9 MAP 1 Hazard and flooding scenarios Rivers with catchment areas >4000km 2, lakes >100km 2, transitional and coastal waters will be shown on the map at the level A. Two scenarios (floods with medium and low probabilities) for rivers with catchments >4000km 2 will be shown on one map. The large areas will be displayed as polygons, smaller areas as lines or dots (the same criteria as used for the APSFR map). The outlines of polygons should have zero thickness. If no info is available, country s area will be displayed with a grey overlay. Red color will be used for extreme events and orange color for medium probability floods.

11 MAP 2 Risk and population A4 map showing country borders, country capitals, the Danube River but no tributaries. The number of affected population in each country will be shown by a bar chart with 3 bars per each country (one bar for each scenario). 2D bars will be used, data for high probability scenario will be shown on the left side of the graph and the number of affected population will be indicated on top of the bars. Red color will be used for low probability floods, orange for medium probability floods and yellow for high probability floods. Percentage of the affected population has to be shown in a separate table.

12

13 MAP 3 Risk and economic activity Three A4 maps will be prepared (one for each scenario) showing country borders, country capitals, the Danube River but no tributaries. Each map should show the percentage of the affected area compared to the total affected area as 2D pie chart for each country (the legend of the map should read: Percentage share of inundated area). Corine LC classes were aggregated for reporting on the map. Clear indication has to be made that data are provided for the part of the country belonging to the Danube River Basin.

14

15 MAP 4 Risk and IPPC installations A4 map will be prepared showing country borders, country capitals, the Danube River but no tributaries; The number of IPPC installations in each country will be shown by a bar chart with 3 bars per each country (one bar for each scenario). 2D bars will be used, data for high probability scenario will be shown on the left side of the graph and the number of IPPC installations will be indicated on top of the bars; Red color will be used for low probability floods, orange for medium probability floods and yellow for high probability floods.

16

17 MAP 5a WFD protected areas Areas designated for the protection of habitats or species (Natura 2000 sites designated under Directive 92/43/EEC and Directive 79/409/EEC); A3 DRBMP map of protected areas (DRBMP Map 9) will be superposed by a flood hazard map for low probability floods (extreme events) scenario. The overlapping areas will be highlighted by dark red. Only those parts of flood hazard areas overlapping with protected areas will be shown. All protected areas (bird and habitat) have to be shown by one color Map legend will contain an explanation which types of protected areas are displayed.

18

19 MAP 5b WFD protected areas Drinking water protected areas, bathing and recreational water; A4 map will be prepared showing country borders, country capitals, the Danube River but no tributaries; The number of affected protected areas in each country shown by a bar chart with 3 bars per each country (one bar for each scenario); numbers indicated above bars, no stacked chart distinguishing Pas; 2D bars will be used, data for high probability scenario will be shown on the left side of the graph; Red color will be used for low probability floods, orange for medium probability floods and yellow for high probability floods.

21 EFD Art 7 On the basis of the maps referred to in Article 6, Member States shall establish flood risk management plans coordinated at the level of the river basin district, or unit of management referred to in Article 3(2)(b), for the areas identified under Article 5(1) and the areas covered by Article 13(1)(b); Member States shall establish appropriate objectives for the management of flood risks focusing on the reduction of potential adverse consequences of flooding for human health, the environment, cultural heritage and economic activity, and, if considered appropriate, on nonstructural initiatives and/or on the reduction of the likelihood of flooding;

22 EFD Art 7 Flood risk management plans shall include measures for achieving these objectives; Flood risk management plans shall address all aspects of flood risk management focusing on prevention, protection, preparedness, including flood forecasts and early warning systems; In the interests of solidarity, FRMPs established in one MS shall not include measures which, by their extent and impact, significantly increase flood risks upstream or downstream of other countries in the same river basin or sub-basin, unless these measures have been coordinated and an agreed solution has been found among MS concerned in the framework of Article 8.

23 EFD Art 8 Where an international river basin district, or unit of management referred to in Article 3(2)(b), extends beyond the boundaries of the Community, Member States shall endeavour to produce one single international flood risk management plan or a set of flood risk management plans coordinated at the level of the international river basin district; The flood risk management plans referred to in paragraphs 2 and 3 shall be supplemented, where considered appropriate by countries sharing a sub-basin, by more detailed flood risk management plans coordinated at the level of the international sub-basins

24 Flood risk management plan FP EG agreed upon following goals of FRMP: Avoidance of new risks; Reduction of existing risks; Strengthening resilience; Raising awareness; Solidarity principle; FRMP will focus on the measures of the transboundary relevance; Secretariat will develop a draft template for collection of the information on measures.
