GIS Approach for Flood Risk Assessment in the Large Irrigation Area of the Western Mitidja Plain (Algeria)

The large irrigation Areas of the Mitidja plain are areas that are frequently prone to flooding, resulting in significant losses for farmers and the agency managing the hydraulic infrastructures. The objective of this study is to develop a model for identifying, evaluating and mapping the flood-prone areas of these LIAs, in order to allow optimal management of hydraulic infrastructures and natural resources. To this end, we have used GIS tools and remote sensing to create a geodatabase of flood-control factors such as lithology, morphopedology, slope, altitude, natural drainage, artificial drainage and land use.
