| Zusammenfassung |
| Rain can be measured and represented in many ways such as point data from
rain gauges, grid data from meteorological radar, or interpolated data. In
this paper we represent rain fields by implementing a rain cell model of
convective rain cells. The rain fields are used as an input to a hydrological
model to test the watershed response to spatial and temporal characteristics
of the rain cells. As a case study we tested an extreme storm event over a
semi-arid watershed in southern Israel. The rain cell model was found to
simulate the rain storm adequately. The use of these modeled cells allowed us
to test the sensitivity of the watershed hydrological response to rain cell
characteristics and it was found that the watershed is mainly sensitive to
the starting location of the rain cell. Relatively small changes in the rain
cell's location, speed and direction may increase watershed peak discharge by
three-fold. |
