Description
The global river flood hazard maps are a gridded data set representing inundation along the river network, for seven different flood return periods (from 1-in-10-years to 1-in-500-years). The input river flow data for the new maps are produced by means of the open-source hydrological model LISFLOOD, while inundation simulations are performed with the hydrodynamic model LISFLOOD-FP. The extent comprises the entire world with the exception of Greenland and Antarctica and small islands with river basins smaller than 500 km^2.
Cell values indicate water depth (in meters). The maps can be used to assess the exposure of population and economic assets to river floods, and to perform flood risk assessments. The dataset is created as part of the Copernicus Emergency Management Service.
This version also includes additional datasets. For each tile, a flood hazard map is available with water depth categorized according to the GloFAS "Flood hazard 100 year return period" static layer. Furthermore, the "spurious_depth_category" band identifies areas where depths greater than 10m are predicted in small channels (less than 3,000km^2) for the 10-year return period, including a 2km buffer.
