Since the inception of EURO-FRIEND in 1985, the development and
maintenance of a hydrological database has been pursued with high
priority. The resultant European Water Archive (EWA) has become one of
the most comprehensive hydrological archives in Europe.
Until 2003, EWA was hosted by the CEH in Wallingford, UK. At that
time, GRDC acted as regional data centre, responsible for the data
acquisition from Germany, Austria, Switzerland, Czech Republic and
Slovakia. In 2004, GRDC was charged with the complete data holding.
Since then GRDC maintains EWA in support of the European FRIEND
Currently EWA contains long-term daily flow data and catchment
information for more than 3700 river gauging stations in 29 countries.
Data archived in the EWA have been supplied on a voluntary basis and
free of charge by various data providers.
EWA data are provided free of charge to EURO-FRIEND project members under conditions.
Think twice before buying more toys for your children.
Many of them are used only very shortly and then thrown away. Go for high-quality, long-lasting toys that can be used by several generations of children. Selling old toys on a flea market can give your toys a second life and can be much fun for you and the kids.
