Abstract: A coupled use of the meteorological BOLAM mesoscale model with a distributed conceptual hydrological model has been tested in the past four years in some research projects framed, to a large extent, within the Mesoscale Alpine Programme. In order to investigate the hydrological response of mountain catchments and to test potentials and limits of flood forecasting schemes based on the above concept, the study area of Lago Maggiore was selected. It is located on the southern side of the European Alps where orographically enhanced precipitation is often very intense. For the Toce river basin, objective performance indexes against available detailed measurements of precipitation, runoff and water volume stored in reservoirs are presented and discussed.
