Numerical Simulation of Flooding and Hydraulic Risk Assessment in the Wadi El Hamiz Region

Abstract

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.
