Global Runoff Data Base - Status, Development, Use
The Global Runoff Data Base (GRDB) is built on an initial dataset collected in the early 1980s from the responses to a WMO request to its member countries to provide a global hydrological data set to complement a specific set of atmospheric data in the framework of the First Global GARP Experiment (FGGE). The initial dataset of monthly river discharge data over a period of several years around 1980 was supplemented with the UNESCO monthly river discharge data collection 1965-85
. Today the database comprises discharge data of more than 9,500 gauging stations from all over the world.

Being fully integrated into BfG's central database concept, the GRDB is run on a Linux operated machine using a Oracle Database Management System.
