Coupling Meteorological and Hydrological Models for Floodforecasting

This paper deals with the problem of analysing the coupling of meteorological meso-scale quantitative precipitation forecasts with distributed rainfall-runoff models to extend the forecasting horizon. Traditionally, semi-distributed rainfall-runoff models have been used for real time flood forecasting. More recently, increased computer capabilities allow the utilization of distributed hydrological models with mesh sizes of 1km and smaller. On the other hand , meteorological models, providing the quantitative precipitation forecast, tend to produce average values on meshes ranging from slightly less than 10 to 200 km. Therefore, to improve the quality of flood forecasts, the effects of coupling the meteorological and the hydrological models at different scales are analysed in the context of the European FP5 project EFFS.
