Abstract
In the sahelian coastal areas, most lowlands are threatened nowadays by the risk of salinization due to climate change. Given the scale of this soil’s degradation, several actions have been undertaken including anti-salt dam. Therefore, the objective of this work was to understand the impact of these dams on the fluctuation of ground water during wet season. The study has been conducted in 2011, in two lowlands, in the Sine Saloum area, in Senegal. Thirty piezometers have been installed in each lowland, in order to follow the evolution of the water table. The dynamics of this water table during the year is strongly correlated with rainfall, evapotranspiration, runoff, infiltration and standing water in the reservoir. We noticed that the salt leaching process by anti-salt dam strongly affects the process of infiltration and discharge of the water table.
