This study aims to identify flood-susceptible areas in the municipality of Man, located in western Côte d'Ivoire, in a context of rapid and disorderly urbanization, for sustainable land management. The method used combines multi-criteria analysis and Geographic Information System (GIS). Five parameters were considered: slope, land use, drainage density, population density, and environmental and anthropogenic factors. Weights were assigned to these parameters using Saaty's Analytic Hierarchy Process (AHP). The flood susceptibility map obtained by combining these parameters using GIS reveals five susceptibility classes (very low, low, moderate, high, and very high). The results indicate that the municipality of Man has low susceptibility to flooding. However, the city of Man is moderately susceptible to flooding, with certain neighborhoods such as Air France, Mistrot, Belleville, and Libreville exhibiting high susceptibility. These results will now guide the decision-making of the authorities responsible for managing the municipality in terms of flood prevention and crisis management. Finally, the findings provide actionable insights for urban planners to mitigate flood risks.
