Global Flood Awareness System (GloFAS) historical data and documentation is now being provided by the CDS.

The aim of GloFAS  is to support preparatory measures before major flood events strike, particularly in the large trans-national river basins and throughout the world.
The CDS is the GloFAS recommended and easiest way to access GloFAS data and all relevant metadata information.

The following link gives access to the entries in the CDS Catalogue for the discovering and downloading of  GloFAS data:  https://cds-dev.copernicus-climate.eu/cdsapp#!/dataset/cems-glofas-historical?tab=overview
