| Zusammenfassung |
| A new domain, the macropore domain describing subsurface storm flow, has
been introduced to the Representative Elementary Watershed (REW) approach.
The mass balance equations have been reformulated and the closure relations
associated with subsurface storm flow have been developed. The model code,
REWASH, has been revised accordingly. With the revised REWASH, a
rainfall-runoff model has been built for the Hesperange catchment, a
sub-catchment of the Alzette River Basin. This meso-scale catchment is
characterised by fast catchment response to precipitation, and subsurface
storm flow is one of the dominant runoff generation processes. The model has
been evaluated by a multi-criteria approach using both discharge and
groundwater table data measured at various locations in the study site. It
is demonstrated that subsurface storm flow contributes considerably to
stream flow in the study area. Simulation results show that discharges
measured along the main river course are well simulated and groundwater
dynamics is well captured, suggesting that the model is a useful tool for
catchment-scale hydrological analysis. |
