Soil erosion is considered one of the major problems in the Mediterranean regions that experience sudden floods and poor water flow control policies. Risk mapping is an essential tool for understanding natural processes affecting the ecology, economy, and citizens of these regions. The present research focuses on finding the flood and erosion-prone zones in a district of Morocco called Fahs-Anjra. By applying a specific method, namely the Analytical Hierarchy Process (AHP), it was possible to achieve an accuracy of 76% regarding erosion probability and 89% with respect to flooding. The produced maps showed that more than 50% of the area had a medium risk for flooding and erosion, while 16% to 37% had a high risk. This would mean their evaluation method is significantly reliable. These results are important to understand in terms of devising flood and erosion mitigation strategies for the future, which is highly relevant to regional planning in these areas.
