Article Title: Geoelectrical Prospection of Aquifers in Eseka Region, Center-Cameroon
by Philippe Njandjock Nouck, Quentin Yene Atangana, Leonel Amougou, Pius Lissom and Mbida Yem

Abstract:
This geophysical study was carried out in the city of Eseka, the head quarter of Nyong and Kelle Division, Center Region of Cameroon. It had as aims to prospect aquifers and to propose models of geophysical structures of the underground basement in the city. To this effect, the geophysical method of electrical resistivity was chosen, due to the local geologic context, and its easy application. With the aid of a resistivitimeter of mark TERRAMETER ABEM SAS 300, twenty (20) electrical soundings were effectuated in different points in the city. The treatment of data was done through several interpretation softwares, such as Geo-Elect. Mod and surfer 8.0. Qualitative and quantitative interpretations, coupled with field and laboratory observations, permitted: the characterization of the lateritic crust constituted of the model of the terrain, into four and five layers of distinct terrain by their resistivity and thicknesses; the definition of the average depth of the upper aquifer from about three (03) meter in the loose clayey level, and the lower aquifer at about thirty (30) meter in the weathering and fractured gneiss level; the localization of the zone of conduction and resistant anomaly, at chosen depths in the study area. These results are important in future modeling process of the aquifers in this area.
Keywords: Eseka, aquifer, electrical sounding, electrical resistivity, geo-electrical cross section.
