Popis: The present hydrogeological study was carried out in the complex basement zone (Dabakala department, North-Central Côte d'Ivoire). Indeed, in this area, the population faces a real problem with the drinking water supply during the dry season. The aim of this study is to carry out a spatial characterization of groundwater potentialities in order to establish productive boreholes in the division. Ten decision criteria were developed and then aggregated. The methodology consisted in building a database based on these criteria, using remote sensing and GIS techniques. These criteria applied multi-criteria decision analysis (MCDA) using the Hierarchical Analytical Process (HAP) for their weighting. The resulting groundwater potential map was validated using the sensitivity trend curve technique. Ultimately, the results indicate that approximately 35% of the division’s area has strong to very strong groundwater potential.
