摘要：Floods are among most destructive natural hazards worldwide. Morocco is not spared from these phenomena; each year socioeconomically losses are recorded in several regions. At the end of November 2014, the Er-Rich village (Central high Atlas of Morocco) knew a heavy rainfall event that had significant flood impacts because of its localization at low topography and at the natural bed of the Ziz River. These floods have been exacerbated by the reduction of floodplain by the uncontrolled urban and agricultural development around the river. This study presents a methodology for the simulation of floods of the Ziz river through three retourn periods (10, 50, and 100 years) in order to identify floods areas and maximum water high that can reach. The studied segment of the Ziz river starts from the north irrigated lands of the village up to the south irrigated lands. The inundation simulation was conducted using hydrodynamic program HEC-GeoRAS based on DEM and land uses data. The obtained results has identified several areas of high flood risk witch should be helpful for future land use planning and for Rich citizens security.
