1 Adopting an approach for PFRA in Austria Drago Pleschko Flood Protection Unit Austrian Federal Ministry of Agriculture, Forestry, Environment and Water Management Seite

2 geographic overview administrative and organisational provisions the basic procedures and methods data sets used for PFRA in Austria further steps page 2

3 Austria and the Danube river basin Basin area: Danube river km² page 3 Austrian part km²

4 River basins and subbasins in Austria Danube km² page 4 95 % Rhine 2400 km² 4% Elbe/Labe 1% 900 km²

5 Administrative bodies responsible for flood risk management in Austria Federal Ministry of Agriculture, Forestry, the Environment and Water Management Federal Ministry of Transport, Innovation and Technology (Unit for Flood Protection of Waterways) Federal Ministry of the Interior (Civil Protection Unit) Offices of the Provincial Governments Departments of Flood Protection Water Management Spatial Planning Civil Protection page 5

6 Organizational arrangements for implementation of FD in Austria BMLFUW Federal Ministry of Agriculture, Forestry, Environment and Water Management Committee on Legal Transposition Technical Implementation Committee Working Working Working Group on Group Group Members: Hazard on FloodExperts onministries Technical of the involved Scenarios Risk Experts of the Provincial FRMP Technical Gov.

7 PFRA: stepwise procedure page 7

8 Basic data-sets on national level Map: Austrian river network for all rivers > 10 km² (used for WFD-reporting) significant flood risk areas along rivers with catchments smaller than 10 km² basis for PFRA and reporting on Floods Directive page 8

9 Basic data-sets on national level Flood zoning system ehora Floods with 30, 100 and 200 years probability on the internet since 2006 basic flood risk information quickly accessible to everyone page 9

10 Basic data-sets on national level Flood zoning system ehora : effect of existing flood protection infrastructure is depicted insufficiently on the maps shape-files for areas of 200 years flood will be used for Federal Draft of PFRA page 10

11 More detailed data on regional / local level Hazard zoning maps: local planning instrument for torrents in alpine catchments and for (smaller) rivers Flood hazard maps: based on hydraulic modelling for longer stretches of (larger) rivers page 11

12 Main data-sets on national level CORINE land cover (CLC 2006): first step for preselecting areas assessment in combination with population data Population data: available for 125 m square grids resident population (principal and secondary residence) persons employed page 12

13 Other data-sets on national level Sources of water pollution: data available from WFD Protected areas: for water and nature protection Ponts of Interest : nation-wide data on historical, educational, cultural, sanitary buildings Infrastructure facilities: roads and railways page 13

14 Further steps Legal transposition: National Committee on Legal Transposition of the FD start meeting in June 2009 Technical issues: Adaptation of Austrian rivers network Examination and consolidation of spatial data sets Further development of PFRA methods Determination of criteria for PSFR and testing in pilot catchment areas Inventory of flood hazard maps for use of Art. 13 page 14
