Global Runoff Data Centre (GRDC)

A global hydrological database is considered essential for research and application-oriented hydrological and climatological studies at global, regional and basin scales. The Global Runoff Database is a unique collection of river discharge data on a global scale. It contains time series of daily and monthly river discharge data of currently more than 9,800 stations worldwide. This adds up to around 435,000 station-years with an average record length of 44 years. The earliest data is from 1987, the most recent for 2019. The database is continuously updated as soon as data is supplied to the centre by national hydrological services.
