Analysis of the Impact of River Erosion in the Saloum Delta: The Case of the Mar Islands (Fatick, Senegal)

A study of the Saloum Delta reveals significant coastal erosion and groundwater salinization risks, particularly around the Mar Islands. Research shows that shoreline retreat rates reach up to -0.96 meters per year on the concave banks, driven by hydrodynamic energy concentration and sediment supply deficits. Conversely, convex banks experience low-energy sedimentation. While deep Paleocene and Maastrichtian aquifers provide primary water sources, they face high mineralization and fluoride levels exceeding drinking standards. The findings highlight the vulnerability of the delta's estuarine systems to both natural and human-induced pressures, emphasizing the need for integrated management of water and coastal resources.
