FLOOD FORECASTING IN THE CRISUL ALB AND CRISUL NEGRU BASINS USING GIS DATA BASE

摘要

Analysing the calibration results the VIDRA model can be considered a good model for flood forecasting. The validation made on the flood event from the spring 2000 and 2001 confirms the calibrated parameters. The results of the simulations obtained using the VIDRA model for a non flood event show that the model is more appropriate for the floods events, for the non-flood events the errors are greater than those accepted for hydrological forecasts. Also, the simulations using different flood events with diverse characteristics of the generating factors show that the model is more adequate for the floods generated by precipitation evenly distributed over the basin. The overall errors are both due to the model errors and to the availability and accuracy of the input data. The main error is found as being stemmed by lack in the spatial distribution of the precipitation over the basin.
