In order to have a greater visibility, we used mapping as a tool to help understand the flood risk and its impact on the environment. This has been useful for the explanation of flood risk. To do this, the flood risk map was developed by overlaying the hazard map and the issue map.
The result of our work can be used as a tool to establish a general plan for forecasting, prevention and protection of flood risk in the watershed of Zat and Ghmat. Such documents are a decision-making tool for risk prevention and a key for strategy conception for mitigation and actions that should be done on the field both before and after inundation. It can enable planners and local authorities to propose mitigation measures in areas likely to be affected by floods and to act more effectively in the flooding events.
The methodology adopted for the evaluation and mapping of flood hazard and flood risk can be transferred to any other flood-prone areas, hence the universality of this work. In order to bring an additional degree of accuracy, we propose some recommendations to improve the quality of the hydraulic modeling for the next studies, we suggest :
