Résumé:
This master’s project focuses on the analysis and simulation of flood risks within the El -Hamiz
watershed. The objective was to assess the vulnerability of the study area to flooding events and to
identify the high-risk zones through numerical modeling. To achieve this, the HEC-RAS software was
used to simulate water flow and flood propagation based on real terrain and hydrological data. A flood
scenario was considered for analysis of water levels and flow velocities across the basin. The study
demonstrated the effectiveness of using hydraulic modeling in flood risk assessment and provided
valuable insights into the behavior of the river system under extreme hydrological conditions. The
results can serve as a decision-making tool for territorial planning and risk prevention. Despite some
limitations related to data availability and model assumptions, this work highlights the importance of
integrating scientific tools into natural hazard management strategies.
