Aquifers Characterization for the Location of Drinking Water Supply Points in Gbangbégouiné-Yati, in the Department of Man (West of Côte d’Ivoire)

This study aims to identify from geo-electrics the areas favorable to the installation of drinking water supply (AEP) drilling in the sub-prefecture of Gbangbégouiné-Yati in order to contribute to a better distribution and management of water tables in the Department of Man. To achieve these objectives, piezometric maps and electrical resistivity maps were produced to understand the functioning of groundwater and to have the imaging of the subsoil. The piezometric maps revealed a regressive trend in the water level in the period from February 2024 to April 2024 and flow towards the lowlands in the north and, more mainly, in the east. Electrical resistivity imaging reveals three types of formations: conductive formations (resistivities between 100 and 1000 Ohm.m), medium resistivity formations (1000 to 3200 Ohm.m), and resistive formations (3200 to 6000 Ohm.m). Low resistivity formations likely to contain water in this locality are located between depths of 40 m and 50 m.
