Extension of the surface water quality modeling Pegase to the Northern part of the Maas basin (German part of the basin)

PEGASE (Planification Et Gestion de l’ASsainissement des Eaux) is an integrated model “basin/river” which makes possible to calculate in a deterministic way the water quality of rivers according to pollutant contributions and releases, for various stationary hydrological situations (see http://hdl.handle.net/2268/35224 for more information). In the scope of the Water Framework Directive international coordination, the transnational surface water quality model PEGASE is already in use (since 2005) for the Southern part of the Meuse basin (France, Luxemburg, Wallonia and a small part of Flanders). It was thus of great interest to extend this surface water quality application to the Northern part of the Meuse basin, i.e. the German, Flemish and Dutch downstream parts of the basin, in order to cover the entire district. This document describes the tasks which were devoted to the Research & Development Unit of the Aquapôle of the University of Liège (Aquapôle-ULg) in order to realize the extension of the Pegase database to the German Maas basin and to run the model on the German watershed.PEGAS
