A recent flood risk assessment in Thiès, Senegal, underscores the city's increasing vulnerability to flooding due to rapid urbanization and the escalating impacts of climate change. The study, which utilized the Flood Potential Index (FPI) integrated with geographic information systems (GIS), meticulously mapped the areas most susceptible to flooding, identifying key factors such as topography, precipitation, urbanization, and the condition of drainage infrastructure. The findings highlight that low-lying areas near drainage networks are particularly at risk, with inadequate drainage infrastructure, soil degradation, and a lack of stringent land-use regulations exacerbating the city's susceptibility to flood events. The flood risk is categorized into five levels, revealing that a significant portion of the area faces moderate to very high risk, necessitating urgent action to mitigate potential impacts.
