EFAS rapid impact assessment

This data set contains the potential impact of floods on population, land use (agriculture, urban) and infrastructures (major roads) for the whole of Europe (aggregated over NUTS regions), based on the EFAS flood forecast. The methodology in brief: Event-based hazard maps (see "CEMS EFAS rapid flood mapping") are combined with exposure information to assess several categories of impacts, aggregated at regional scale. Affected population, roads and cities are computed using related maps at European scale. The extension of urban and agricultural areas affected is computed using the Corine Land Cover. Direct economic losses are computed combining the Corine map with flood hazard variables (flood extent and depths) and a set of damage functions derived for European countries. The information contained in this dataset includes: - estimation of likelihood and impact - population affected (nr. of people) - total roads affected (km) - artificial, agricultural, forest and seminatural surfaces affected (ha) - potential monetary damage (Euro) - cities affected - potentially avoidable damage (Euro) This information is produced by the operational EFAS (www.efas.eu) in order to provide the EFAS partners with a rapid impact assessment affiliated to the flood forecast. The update frequency of this data set is twice a day (00:00 and 12:00 UTC); and the spatial coverage is the extended geographic Europe.
