AI-generated Key Takeaways
-
The JRC Global River Flood Hazard Maps dataset provides global inundation data for seven flood return periods, ranging from 1-in-10-years to 1-in-500-years.
-
The dataset utilizes the LISFLOOD and LISFLOOD-FP models to simulate river flow and inundation, respectively, and covers the entire world except for Greenland, Antarctica, and small islands with river basins smaller than 500 km².
-
Cell values in the dataset represent water depth in meters, allowing for assessment of population and economic asset exposure to river floods.
-
Created by the Copernicus Emergency Management Service, the dataset is freely available for use and distribution without restrictions.
-
The dataset can be explored and analyzed using Google Earth Engine, a platform for scientific analysis and visualization of geospatial datasets.

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.
