Flood risk management in two Moroccan watersheds: Fès and Beni Mellal

The project concerns two Moroccan watersheds in urbanised areas: Fès and Beni Mellal. The research is carried out through two PhD theses, one at the University of Fès (Mohamed Lasri), concerning Fès watershed, the other one at the University of Lausanne (Gabriela Werren), concerning Beni Mellal watersheds. The research is divided in four main steps: (1) Geomorphological mapping and cartography of human impacts on hydrology (urban extension, communication network, water embankments, etc.). This phase allows us to elaborate a map of phenomena and a map of vulnerability. (2) Hydrological analysis of both watersheds. (3) Elaboration of an indicative map of flood hazards of both watersheds (scale 1:25'000). The map is realised using the Swiss hazard mapping approach and hydrological imputs by the Moroccan partners (4) Synthesis and elaboration of recommendations for water managers. The project is aimed at improving integral management of hydrological hazards in Morocco, in close relationship with territorial management issues, as well as reinforcing University co-operation between Switzerland and Morocco.
