Sažetak

High resolution numerical simulations of recent flash-flood events that have occurred over Mediterranean coasts are used to underline the physical mechanisms leading to the stationary of the precipitating systems and the predictability associated with such events. Three cases, including the two last extreme flash-flood events over Southeastern France, have been simulated : the 12-13 November 1999 catastrophe over the Aude region (MAP IOP16), the 8-9 September 2002 flash-flood over the Gard region and the less paroxysmal event of 13-14 October 1995 over the Cévennes-Vivarais relief. Sensitivity to the initial conditions, to the Massif Central relief and to the Sea Surface Temperature (SST) has been studied.
