Abstract
The present study deals with the geophysical part of a comprehensive groundwater exploration project being executed in Bodeyel, Karaftayi and Kazaure town by Water Resources and Engineering Construction Agency. Eleven vertical geoelectric Schlumberger grillings (soundings) were conducted along the chosen profile of each area in order to study the layer parameters governing groundwater occurrences in the subsurface strata. The collected data have been reduced and analyzed automatically using an appropriate advanced computer software. In this respect, the geoelectric drilling data were subjected to inversion program of an n-layered model analysis. The results of the analysis are presented as subsurface layering and subsurface resistivity contour our sections The geologic interpretation of the automatically interpreted data result was used in the construction of the subsurface equivalent geologic section of each profile. The geologic sections have revealed that the top and bottom layer have high resistivity values (1,000 to 7,000 Qm) while the middle layers have intermediate resistivity of less than 1,000 Qm. In addition, a close examination of the equivalent geologic sections indicates that there exists points with complementary combination of layer parameters that favour highest Groundwater accumulation and storage. Such points have been selected and recommended as the best location of boreholes. These are BD06 (Bodeyel) , KT07 (Karaftayi) and KZ03 (Kazaure town).
