The GRDC Global Freshwater Fluxes into the World Oceans are re-calculated and displayed for land areas associated with the UNEP GIWA Regions (UNEP, 2014) and as well freshwater fluxes from the 5° cells along the continent's coastlines. Freshwater fluxes calculated per 5° and 10° latitude bands show how much freshwater flows from a specific continent into a specific ocean.

Basic hydrological statistics of timeseries data of the gauging stations being represented in the Global Runoff Database. Annual characteristics are derived from monthly discharge data, either aggregated daily data or originally provided monthly data. Long-term statistics and long-term variablity are derived from annual characteristics

The Global Composite Runoff Fields product was developed in a cooperation between the Water Systems Analysis Group (WSAG) at CSRC of University of New Hampshire (UNH) and the GRDC. It demonstrates the potential of combining observed river discharge information with a climate-driven water balance model in order to develop composite runoff fields which are consistent with observed discharges.
