Abstract
Flood risk management, since long based on the hazard control, is increasingly orientated towards an attempt to reduce the vulnerability of territories. In fact, the dangers of flood risk on the territory of Casablanca have been the subject of numerous analyzes, whereas studies on the vulnerability of Morocco’s first economic city are very rare. This work aims to contribute to the development of methods for assessing the vulnerability of the urbanized watershed area of Oued Bouskoura facing the overflow of the latter in case of storm floods. The methodology of this study is the use of a geographic information system coupled with the hierarchical multi-criteria analysis developed by T. Saaty (Saaty 1980) for the identification and quantification of urban elements lying in the natural course of Oued Bouskoura and are at risk of flooding.
