European and global flood hazard maps available
Two datasets of high-resolution flood hazard maps for Europe and the World are now freely available for download at the JRC Data Catalogue: http://data.jrc.ec.europa.eu/collection/floods.
Especially in developing countries and data-scarce regions, these maps can be a valuable tool for local authorities and water managers to mitigate flood risk and reduce catastrophic impacts on population and assets.
The flood hazard maps have been developed using the most recent advances in large scale flood modelling, and are provided with a resolution of 100m for Europe, and 30’’ (~1km at the Equator) for the World, for return periods from 1-in-10 year to 1-in-500 year. The 1-in-100 year global hazard map is also on display on the GloFAS website. Please note that the maps provided are NOT official flood hazard maps, and might differ from official national maps due to their inherent limitiations and assumptions.
