Characterization of the productivity of basement aquifers at Bagoué region (North of Côte d’Ivoire)

This study aims to characterize the productivity of basement aquifers based on a database built by pumping test and drilling report from eighteen boreholes exploited in Bagoue region Cote d’Ivoire. By using last version tool assist interpretation suggested French Mining Geological Survey, Transmissivity parameter values confined were determined through well-known Theis method. In same approach, critical yield value borehole was at equivalence point linear quadratic pressure drop short-term data. Geostatistical analysis kriging transmissivity realized. Then, it elaborated few predictive equations between hydrodynamic hydraulic parameters their relationship level. Comparison capacity ended methodology. ranged 9.10-7 4.10-5 m2.h-1 while specific reached 0.34 23.07 m3.h-1. Yields varied 0.5 m3.h-1 12 with an average reaching 3.44 Critical 2.11 18.8 6.95 According geostatistical Transmissivity, its spatial spreading adjusted spherical model range 0.13 meters. Findings highlighted 44 % aquifer areas characterized low great outflow. That suggests availability drinking water for living communities. way, 11.11 established into outflow that better supply environment long-term groundwater availability.
