The use of GIS in geotechnical studies and the design of large hydraulic structures Case study of the upper basin of Saf Saf Wadi in the El Malabiod region (Northeast Algeria)

Abstract

The El Malabiod plain is located in the northeast of Algeria in the province of Tebessa. 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.).
