The eastern region of Morocco is characterized by an arid to semi-arid climate. It often confronted with heavy rainfall episodes that can generate floods cause adverse human and property damage. This work studies hydrological risk in the SidiBoulenouar area (Oujda province) model map areas. method used determine watersheds their watercourses, then calculate flows mathematical formulas. Topographic data were extracted from a 12.5-m resolution DEM derived ASTER (Advanced Spaceborne Thermal Emission Reflection Radiometer). GDEM (Global DEM). was delimit hydrographic network ArcMap software. use HEC RAS 1D necessary flooding area. results hydraulic modeling centennial flood showed four ephemeral watercourses landlock rural at time floods.
