The paper illustrates impact studies of land use changes on the water balance in meso and macroscale river basins. Problems of impact studies in large river basins result mainly from a huge heterogeneity inside and the relative rough input database. Simple approaches are needed to setup possible land use changes on the basis of easily available spatial data. The investigations are carried out for the river basins of the Saale (24000 km²) and the Havel (19000 km²), two main tributaries of the Elbe River. The hydrological simulations were done with the modelling system ArcEGMO (Becker et al., in: Mathematical Models of Watershed Hydrology, Water Resources Publications, Littleton, CO, 2002).
