| Zusammenfassung |
| Flood forecasting is of increasing importance as it comes to an increasing
variability in global and local climates. But rainfall-runoff models are far
from being perfect. In order to achieve a better prediction for emerging
flood events, the model outputs have to be continuously updated. This
contribution introduces a rather simple, yet effective updating procedure
for the conceptual semi-distributed rainfall-runoff model PREVAH, whose
runoff generation module relies on similar algorithms as the HBV-Model. The
current conditions of the system, i.e. the contents of the upper soil
reservoirs, are updated by the proposed method. The testing of the updating
procedure on data from two mountainous catchments in Switzerland reveals a
significant increase in prediction accuracy with regards to peak flow. |
