Global Runoff Database - Status, Development and Use

The Global Runoff Database (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 7.000 gauging stations from all over the world. Since 1993 the total number of station-years has increased by a factor of around 10.

Being fully integrated into BfG's central database concept, the GRDB is run on a 4-processor Linux operated machine with 4 GB RAM using a Oracle 9i Database Management System.
