Alpine floods of August 2005: European Flood Alert System, post-event summary report

From the 22nd until 27th August 2005, the northern Alpine region was hit by severe floods. The European Flood Alert System (EFAS), under development and running in pre-operational mode at the JRC since February 2003, forecasted these events in all river basins and reported in realtime to its partners’ organizations in the Member States. This report describes what was forecasted with the EFAS system, what was communicated to the EFAS partners’ organizations (water authorities in the relevant countries), where and when the floods occurred and which feedback was received from the end-users. Lessons learnt are described at the end of the report.
