Global Runoff Data Center (GRDC)

The GRDC is an international archive of data up to 200 years old, and fosters multinational and global long-term hydrological studies. Originally established three decades ago, the aim of the GRDC is to help earth scientists analyse global climate trends and assess environmental impacts and risks.

HydroATLAS

HydroATLAS offers a global compendium of hydro-environmental sub-basin and river reach characteristics at 15 arc-second resolution.

HydroBASINS

HydroBASINS is a series of polygon layers that depict watershed boundaries and sub-basin delineations at a global scale.

HydroLAKES

HydroLAKES is a database aiming to provide the shoreline polygons of all global lakes with a surface area of at least 10 ha.

HydroRIVERS

HydroRIVERS is a database aiming to provide the vectorized line network of all global rivers that have a catchment area of at least 10 km2 or an average river flow of 0.1 cubic meters per second, or both.
