Assessing the effects of land use changes on floods in the Meuse and Oder catchment

Recently, dramatic flooding occurred in several regions of the world. To in vestigate the causes of the flooding and the influence of land use. soil ch aracteristics and antecedent catchment moisture conditions, the distributed catchment model LISFLOOD has been developed. LISFLOOD simulates runoff in large river basins. Two transnational European river basins are used to tes t and validate the model: the Meuse catchment (France, Belgium, Germany and The Netherlands) and the Oder basin (The Czech Republic. Poland and German y). In the Meuse and Oder catchment, land use change information over the p ast 200 years is processed at the moment. The LISFLOOD simulation model is used to simulate the effects of these land use changes on floods. Some infl uences of land use and vegetation on the water balance are clear, such as t he changing vegetation cover (leaf area index) which will influence evapotr anspiration. However, not so much is known about the influences of vegetati on on soil properties, which influence infiltration, soil water redistribut ion, throughflow and groundwater recharge.
