ABSTRACT: A combined remote sensing (via Landsat 8 images) and geoelectrical investigation was carried out in order to remedy deficit in water resources in the Messondo area, Nyong and Kelle division (Centre Region of Cameroon). The remote sensing results (fractures, fracture density and land use maps) allowed the delineation of areas of densely fractured basement, which are favourable areas for infiltration and hydraulic capture. These zones are used to guide the geoelectrical survey. The geoelectrical sounding consisted in IP tomography, boreholes and DC electrical Schlumberger profiling along 4 SE-NW lines. The geoelectrical 2D data inverse modelling depicted the vertical and lateral variations of resistivity and chargeability. The joint analysis of these two parameters, combined with the geological observations from the area, permitted to discriminate the potential aquifers from the prospective mineralised targets. The 3D models obtained from the combination, then interpolation of the 2D models, permitted to visualise and quantify the identified aquifers in Messondo. Two types of aquifers arise from these 3D models: 1) shallow subsurface aquifers located in the unconsolidated laterites; they spread over the entire surface and they are found down to 39 m depth, thus defining the thickness of the altered layer; 2) The second type of aquifers, exclusively located to the east of the area, in the fractured gneisses.
