  1. Readily available flood information resources Ad de Roo, Peter Salamon, Hannes Reuter, Steve Peedell, Javier Gallego COM – DG Joint Research Centre

  2. Could be used for: Background data layers to show in reporting system (WISE) Flood hazard & risk mapping by MS If no higher resolution/quality are readily available Potential data layers, readily available: CORINE land cover (EEA) Population density Elevation (SRTM), with derived products: Potential river flood hazard areas Potential coastal flood hazard areas EPER Location of industrial and waste management activities Transportation infrastructure Available information

  3. Land cover map from photo-interpreted Landsat-TM images 44 classes Could be simplified to 7-9 classes Minimum mapping unit: 25 ha. Smaller patches swallowed by dominant class heterogeneous classes if no one is dominant (~10% of the total area) CORINE Land Cover Data held at EEA Topic Centre Land Cover

  4. Population density • Starting data: Population per commune and CORINE Land Cover. • Result: Approximate population density with 1 ha resolution (GIS grid) + = Data held at JRC

  5. SRTM data, corrected by JRC for voids (originating from radar methodology) Seamless data set for entire world: ~90m resolution, between 58S and 60N Absolute accuracy (+/- 16 m), relative accuracy much better Not corrected for vegetation and building height (yet) SRTM elevation data http://srtm.jrc.it SRTMv3 and SRTMv4

  6. 100m resolution Showing elevation difference with nearby river (in m) Based on: JRC SRTM elevation JRC CCM2 river network SRTM derived products: elevation difference with nearby-river Data held at JRC

  7. 100m resolution Based on: JRC SRTM elevation Areas < 2m above sea level SRTM derived products: elevation difference with nearby-sea: potential coastal flooding Data held at JRC

  8. 100m resolution Based on: JRC SRTM elevation JRC CCM2 river network JRC LISFLOOD / EFAS waterlevels Analysis done for current and future climate Economic damage and population affected being examined Potential river flooding, based on SRTM elevation differences and estimated max waterlevels Data held at JRC

  9. EuroDEM (~60m) - Accuracy (8-10m), TIN or raster possible, 27 MS + 4 EFTA License fees (?) ASTER G-DEM ( ~30m) - Accuracy (+/-7m) - release planned for 2009 GEOS product License fees (?) JRC activities – compilation of auxiliary DEMs for SRTM void filling SPOT 3D product (~35 Mio. Euro for 10 user licence for EU27) Elevation data (DEM) products under development

  10. Dartmouth Flood Observatory: historic floods http://www.dartmouth.edu/~floods/

  11. European Pollutant Emission Register (EPER) (EEA) Energy industry, chemical industry, waste management, other industry Transportation infrastructure (TeleAtlas, currently only JRC license) Map of current/ongoing flooding in Europe Map of current alert level (no discharge values or waterlevels) Could be combined with web-links to relevant water authority websites for in-depth info Could be based on ongoing JRC-GRDC ETN-R project, funded by the IDABC programme (exchange of realtime discharge data in Europe to GRDC), in support of the European Flood Alert System (EFAS) at JRC Map with web-links and areas of the relevant water authorities for flooding JRC is creating and maintaining this for the European Flood Alert System (EFAS) in any case Other possibilities

  12. Possibilities for display of flood maps in WISE Using e.g. Google Earth

  13. EFAS on-line • web-based user interface • password protected • access any time • different user access rights • simplified EFAS warnings

  14. EFAS on-line • web-based user interface • password protected • access any time (24/7) • simplified EFAS warnings • updated 2x daily http://efas-is.jrc.it

  15. Drought Products at JRC, as part of European Drought Observatory (EDO) Daily Soil Moisture Anomaly http://natural-hazards.jrc.it

  16. Temperature and Precipitation changes (A2 scenario, DMI 12km)

  17. Future changes in precipitation Indicator for change in plain flood frequency

  18. All open for discussion..
