Estimation of Road’s Exposure to Floods in the Province of Larache, Morocco

Generally, the road infrastructure suffers from significant damage caused by natural disasters (flood, earthquake, etc.). In particular, the Kingdom of Morocco experienced several interruptions of the road network during previous floods. In this sense, paper presents a new method for estimating the exposure’s degree of the road infrastructure to the risk of flooding. This method has been applied to the province of Larache. Based on the flood history, a model is developed to define areas exposed to flood hazard and deduce the exposure’s degree of each road to floods. Several results are obtained allowing a detailed mapping of flood risk in the province of Larache.
