Description :
The AA. consider the recharge-related flooding of a bare karst, with a case study of a Mediterranean area dominated by semi-arid climate. In these cases floods are rare, short, and sudden but the effects are often very dramatic. Three types of analyses were used : the historical analysis, the hydrological analysis and the geomorphological analysis. The hydro-geomorphological analyses showed the peculiarities of the 2005 flood event. The maximum rainfall return period for the 2005 event was due to exceptional three-hour cumulative rainfall. This study shows that it is possible to estimate peak flow characteristics even when time series of river flows are not available, thereby it improves the capability to forecast the flooding effects of severe storms in karstic area.
