Étude de la productivité d’un aquifère de socle et approche statistique pour la détermination des tranches de profondeurs potentiellement productives : cas de la région de Bongouanou, est de la Côte d’Ivoire

Abstract: Dans le département de Bongouanou, l’essentiel de l’approvisionnement en eau potable de la population est assuré par les eaux souterraines contenues dans les aquifères de socle des granites et des schistes. Malheureusement, plus de 20 % des forages réalisés sont négatifs, en raison de leur trop faible productivité. Ce travail a donc pour objectif d’améliorer la connaissance de ce type d'aquifère et d’évaluer ses potentialités en eau souterraine. Pour ce faire, des analyses statistiques des paramètres hydrogéol… Show more

“…[52] [53]). This value of infiltration obtained in the study area is greater than those obtained in the basement aquifers of the city of Yaoundé (5.7%) [9] and lower than that (12%) obtained in Bongouanou (East of Ivory-Coast) [54]. The difference between these values could be mainly related to differences in climate whose impact on groundwater recharge would be exacerbated by the different geology, soil, vegetation cover and topographic slope in the regions.…”

“…These results are not too different from those obtained with the method used for this study. Nevertheless, an aquifer with a high value of transmissivity is the more productive [3] and the upper part of a fractured aquifer is also more productive [54]. Furthermore, the productivity is not related to the depth of a borehole [60].…”

“…The aquifers in this area contain a well-distributed water resource with little dependence on surface water [4]. Although the volume of water stored in these aquifers is not as substantial, they contribute to the socioeconomic wellbeing of both rural and urban populations [5,6]. However, the rapid population growth, the improvement of living conditions, and the increase in water use due to economic activities contribute to increasing pressure on groundwater resources [7].…”

“…This result complements other work done in Côte d'Ivoire. Indeed, in the region of Oumé it appears that the slice (0-30 m) of thickness of alterites is conducive to obtaining strong flows [21] in Bondoukou between 10 and 40 or even 45 m [9] and in Bongouanou between 70 and 80 m [22]. Regarding depth, [23] estimated that there is a depth beyond which the chances of finding a good flowing aquifer horizon are negative, specifically in the altered basement rocks.…”
