Abstract : Floods are a recurring problem in the Mediterranean region, and understanding their frequency and severity is crucial for local decisionmakers. This paper presents a methodology for assessing flood risk at the watershed scale, using the frequency of floods and land-use vulnerability as key factors. The study focuses on the Kert basin, which includes the urban area of Driouch, and aims to produce a flood risk map for the region. The methodology involves a hydrological study to determine the maximum flow rate and a hydraulic study using HecRas software to calculate the speed and height of centennial floods in the Oued Kert. The results are presented as thematic maps using ArcGIS 10.7 software, enabling planners and local authorities to propose mitigation measures and respond more effectively to floods. The study found that the region is highly susceptible to flooding, particularly as urbanization and infrastructure continue to expand. The paper concludes by emphasizing the importance of flood risk management for the region's sustainable development.
