摘要：

A semi-distributed rainfall-runoff model is proposed. This model is able to use distributed rainfall fields, particularly from weather radar, and it is thought to be adapted to hydrological characteristics of Mediterranean basins. The catchment is split into hydrological cells of 1x1 km(2), and TOPMODEL is applied at this cell scale, as runoff generation procedure. Afterwards, effective rainfall is routed to the basin outlet, using a cell unit hydrograph which depends on the properties of the travel path. Each cell pathway is divided into hillslope path (slow response) and river path (fast response). Finally, all the cell runoffs are added, getting the total runoff. A case study in the Ample basin is presented. A calibration-validation process has been carried out over a set of events, and some results are shown. A comparison against a lumped version of TOPMODEL (using spatially uniform rainfall) is also made. Results show that in general the proposed version can provide better flow reconstitutions, allowing the integration of radar data into distributed hydrological modelling, (C) 2000 Elsevier Science Ltd.
