| Zusammenfassung |
| WaSiM-ETH (Gurtz et al., 2001), a widely used water balance simulation
model, is tested for its suitability to serve for flow analysis in the
context of rainfall runoff modelling and flood forecasting. In this paper,
special focus is on the resolution of the process domain in space as well as
in time. We try to couple model runs with different calculation time steps
in order to reduce the effort arising from calculating the whole flow
hydrograph at the hourly time step. We aim at modelling on the daily time
step for water balance purposes, switching to the hourly time step whenever
high-resolution information is necessary (flood forecasting). WaSiM-ETH is
used at different grid resolutions, thus we try to become clear about being
able to transfer the model in spatial resolution. We further use two
different approaches for the overland flow time calculation within the
sub-basins of the test watershed to gain insights about the process dynamics
portrayed by the model. Our findings indicate that the model is very
sensitive to time and space resolution and cannot be transferred across
scales without recalibration. |
