30 years of operating the Global Runoff Database

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 9,500 stations worldwide. This adds up to around 415,000 station-years with an average record length of 43 years. More : 30 years of operating the Global Runoff Database

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. Positioned as a facilitator for exchanges between data providers and data users, the GRDC has become a focal point for international cooperation. Researchers, universities and other organisations make use of the facilities available for research programmes and projects.
