标题：Contribution of Electrical Resistivity Method to the Location of Aquifers of Precambrian Basement in the Department of Tanda (North-Eastern Côte d’Ivoire)
摘要：The complexity of fissured aquifers, the lack of exhaustive studies about these aquifers and bad choice of drilling’s sites make difficult access to groundwater. That explains lack of water supply to population in the Department of Tanda. The main objective of this study is to identify success indicators of drillings establishment by using electrical resistivity methods such as Electric Trailing (ET) and Electric Sounding (ES). Electric profiles highlighted discontinuities and geologic structures such as vein zones, fractures, faults and geological contacts. Electric curves of surveys allowed to distinguishing three levels: lateritic cuirass, clay-sand weathered material and bedrock. Also, curves such “peak in trough” and "staircase on the rising branch" and other indices, reveal some conducting anomalies which are potentially aquifers zones.
