ANALYSE DE LA PRODUCTIVITÉ DES AQUIFÈRES DE FISSURES DU SOCLE PALÉOPROTÉROZOÏQUE DE LA RÉGION DE KATIOLA (CENTRE-NORD DE LA CÔTE D’IVOIRE)

Abstract

In the area of Katiola, the main part of groundwater resources is contained in the discontinuous aquifers of the paleoproterozoïc base.This study relates to the analysis of the productivity of the aquifers fissured of the area starting from an approach which takes into account the comparative analysis carried out on the one hand with the flows and physical parameters, flows and lithology, flows and transmissivity and, on the other hand an ACPN of these parameters.The various results contribute to known the hydrogeological potentialities of the area of Katiola. The depths most productive meets between 30 and 75 m. The section from 20 to 50 m of weathered material offer the best flows.67% of the flows met in the area are weak, that can be charged to the lack of studies before the establishment of the works.The most productive AE are located in the first 35 meters under the base of altérites.The schists are more productive than the granites
