Welcome to the Global Runoff Data Centre This is the Global
Runoff Data Centre, a repository for the world's river discharge
data and associated metadata. The GRDC is an international
archive of data up to 200 years old, and fosters multinational
and global long-term hydrological studies. Originally
established two 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

universities and other organisations make use of the facilities
available for research programmes and projects. The Global

nearly 9000 stations in 157 countries. This adds up to around
360.000 station-years with an average record length of 40 years.
