Contribution of the Hierarchical Analysis Process (AHP) in the Assessment and Mapping of Flood Risks on the Allada Plateau
摘要
Flood vulnerability mapping and assessment is an important part of flood prevention and mitigation strategies, as it identifies the most vulnerable areas based on physical characteristics that determine flood propensity. This study aims to identify and map the factors related to flood risk on the Allada plateau using a multi-criteria approach, in particular the technique of the hierarchical analysis process (AHP) of Saaty and geographic information systems. (GIS). The method of multi-criteria analysis used in this study made it possible, thanks to the weighting of the different decision criteria, to establish different thematic maps on the flood hazard and vulnerability to flooding.
