Abstract:
The present contribution is a study about parameter sets regionalization for process oriented hydrological models in the case of flash floods. MARINE model performances are tested on 117 flash floods from the last two decades which is a large catalogue of hydrology and landscapes from Pyrenean, Mediterranean, Cévennes-Vivarais and Provence regions. Encouraging results are obtained with two similarity approaches. Only a small decrease of performances from calibration/validation to regionalization is detected for these two methods. This study sheds more light on the importance of hydrological information that is available in calibration events for a gauged catchment or from donor catchment(s) for regionalization. It can also be shown that the most sensitive parameter of MARINE model (Garambois et al 2013) which is controlling the soil volume and water balance, is rather well constrained by the two similarity approaches thanks to bedrock descriptors.
