| Zusammenfassung |
| The hydrological catchment model WaSiM-ETH (Water Balance Simulation Model)
is a spatially distributed, process- and grid-based hydrological catchment
model which was primarily developed to simulate the water balance of
mountainous catchments. In this study, the ability of WaSiM-ETH was tested to
describe the hydrological processes of lowland catchments. In addition, the
resulting model performance was related to subcatchment characteristics and
the model's sensitivity to possible future land use change. The prediction of
the hydrological effects of land use change is a major challenge in
contemporary hydrological model applications. The study revealed that
WaSiM-ETH is a suitable tool for the simulation of the hydrological behaviour
of lowland catchments. However, for a few subcatchments model validation
failed. Analysing the correlation between model performance and physiographic
catchment characteristics revealed that WaSiM-ETH performs better in sloped
catchments compared to plane ones. Modelling results were also better in
heterogeneous catchments with respect to soils and vegetation compared to
homogenous ones. However, the hydrological reaction to land use change
scenarios was similar in all investigated catchments. |
