In the time 23-24 April 2007, in the Koblenz, Germany, had a place International workshop “European Terrestrial Network for River Discharge (ETN-R)”

There are was a lot of participations from different European countries: Germany, Moldova, Russia, Croatia, Italy, Serbia, England, Poland, Norway, Sweden, France, Macedonia, Montenegro, Estonia, Latvia, Lithuania and Netherlands.

Lessons learned from the recent flood events in Europe have shown that data collection and transmission of these data across administrative and country borders is an issue that becomes increasingly important for effective river basin management. Floods do not stop at borders, and increasing preparedness includes having access to the current state of the flood situation in the river basin as a whole. Projects such as EFAS illustrate the benefit of catchments based forecasting for early warning in a convincing way.

Catchment based forecasting evokes a number of organizational and technical questions in relation to the collection and transmission of river gauging data. A workshop has organized to discuss these questions in relation to the ETN-R project and to come to a joint understanding of these issues on a European level.
