| Zusammenfassung |
| Regional climate change scenarios were studied with the water balance model GROWA (Kunkel and Wendland, 2002) to predict the temporal development of mean long – term total runoff, direct runoff and groundwater runoff, including regionally dif-ferentiated analyses for river basins, regions and administrative units. Special emphasizes was given to the regionally differentiated prediction of the mean long-term impacts on groundwater recharge, which determines both, the river discharge and ecological status of rivers during dry periods, as well as the upper limit for the sus-tainable abstraction of groundwater (e.g. prognosis of groundwater hydrograph trends in regions, where water supply is fed from groundwater). As a reference, the GROWA model was calibrated and validated for the hydrological period 1971 – 2000 in an area of ca. 90.000 km² in the North – Western part of Germany, i.e. for the entire Federal States of North Rhine - Westphalia, Lower Saxony, Hamburg and Bremen. |
