Calibration of a rainfall-runoff model using radar and raingauge data
Résumé
The purpose of this study is to compare the capability of the two different measurement systems in order to give correct input to drive rainfall-runoff models. Therefore a geomorphological model was calibrated, using firstly raingauge data and secondly radar rainfall estimates, for the Treja river basin. In this way it is possible to determine different sets of parameters and the influence of measurement system in hydrological modelling.
The results shown that radar rainfall data is able to improve significantly hydrographs reconstructions.
