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.
