The groundwater contained in the formations of the Continental Terminal (CT) of Lower Casamance (South-West of Senegal) is the main source of water supply for the populations. Found at shallow depths (less than 30 m), that groundwater, with proven hydraulic performance, coexists with a dense hydrographic network characterized by the estuary of the Casamance River and the Kamobeul, Bignona, Diouloulou’s backwaters (bolons) where salinities exceed those of the ocean (inverse estuary). This environment associated with the deficient rainfall conditions challenges us on a real need to understand the superficial aquifer system from both a qualitative and a quantitative point of view. This article presents the results of a hydrodynamic characterization of the CT aquifer system. The model implemented with the ArcGIS software made it possible to map the transmissivity and the static level of the groundwater of the low Casamance CT slick by using the geostatistical method.
