It occupies part of the Chott Melghir basin and features a semi-arid climate. The El Malabiod basin includes three sub-basins (Al Goussa, Malassoued, and E'Zned), all of which drain into the El Malabiod wadi. This study aims to calculate the morphometric parameters of these sub basins and estimate the liquid flows by integrating GIS tools. Additionally, it seeks to draw a flood susceptibility map for the El Malabiod basin, with the goal of reducing flood risk and better managing excess surface water for potential storage works (dams, reservoirs, etc.).enTebessa, El Malabiod, Flood, Morphometric Parameters, GISThesis
