European Water Archive (EWA)
European Water Archive: 4105 Stations in Europe
The development of a hydrological database, the European Water Archive (EWA), has been a central feature at the inception of the EURO-FRIEND-Water Programme in 1985. EWA is now one of the most comprehensive hydrological archives in Europe, containing long-term daily flow data and catchment information from more than 4000 river gauging stations in 30 countries.
EURO-FRIEND-Water Project Group 1 had formal responsibilities for coordinating data acquisition and dissemination to FRIEND-Water researchers. The Global Runoff Data Centre (GRDC), Federal Institute of Hydrology, Koblenz, Germany, hosts the European Water Archive.
Data acquisition as part of the European FRIEND-Water programme and the maintenance of a separate EWA database became increasingly difficult to justify, considering the limited number of data requests. GRDC embarked on a strategy of integrated data acquisition, including EWA data, and all supplied data are now been included in the GRDC database.
