Validation of Groundwater Potential Zone Based on Imaging Profiles using Different Array and Lines of Survey Position

[摘要] Two resistivity and induced polarization surveys were carried out in this study to validate the groundwater potential location. These 2D geo-electrical survey lines were perpendicular to each other and intersected at point E. The survey lines used a different array configuration; pole-dipole and Wenner-Schlumberger for AB and CD lines, respectively. The surveys were conducted using set of ABEM Terrameter SAS 400 which resulted a resistivity and induced polarization imaging profiles after an analysis in RES2DINV software. The results revealed that, both induced polarization profiles have a low chargeability values of between 0 - 10 ms at intersect point, E even though the resistivity values varied. Thus, the results have verified the location to be a highly potential groundwater reservoir. The reservoir may be found around 50 m depth below ground surface.
