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.
