| Zusammenfassung |
| A distributed rainfall-runoff model capable for real time flood forecasting
utilizing highly spatial and time resolution data was developed. The study
region is located under the WSR-74 S-band 100 km radar umbrella and is
equipped with a number of rain gauge recording stations, a permanent
installation for flow measurement and a stage recorder. The entire basin was
digitized to 2×2 km2 grid squares by implying GIS techniques. A series
of rainfall events recorded producing floods were analyzed and processed.
The linear channel parameter assigned to each grid-square is based on its
location measured by the centroid of the grid square along the channel
network. The estimation of the hill-slope and the stream velocity are
calculated based on the Geographic Information System (GIS) procedures. |
