Résumé
Certain rural settlements situated in the floodplain area are exposed to a high risk of flash-floods, in case a sudden damage appeared in the supply water system network. The purpose of the present research is the anticipation of hydrological risk in this type of areas in case of a simultaneous occurrence of two types of hazard: torrential rain and damages to the supply water system network. Therefore we will use an ArcGIS procedure of building flash-floods scenarios generated by extreme events, namely the high level of soil saturation, damages to the supply water system network and a high intensity torrential rain. The article presents different scenarios according to the return period (T) of the torrential rain: T= 20 years, T=100 years and T=1000 years. The results will highlight the several vulnerability categories of the terrain and households related to combined risk. The flash-floods scenarios in the rural settlements that benefit from a supply water system network will be of great use to the local administrative authorities for the management of combined risk emergencies.
