Abstract

Flooding has a wide range of impacts on societies and natural environments. In this sense, the city of Fez suffers from these problems reflected by the overflow of Oued El Jawaher during the rainy periods. This situation led the authors to compare between the current situation and the situation developed by the thresholds of Oued El Jawaher. HEC-RAS hydraulic model consists of 31 cross-sections, which will be used in the course of this study. The simulations will concern the current state and the developed state for flows of different frequencies. The result of the simulations confirms that the capacity of the proposed hydraulic structures is insufficient to transit and should be considered. To conclude, the development of the channel by thresholds, which serves for the creation of water plan, magnifies the risk of an overflow of the banks of the canal by the water line along with the longitudinal profile.
