Ground magnetic and resistivity surveys for groundwater exploration

Abstract

Ground magnetic and resistivity surveys were conducted for groundwater exploration. Magnetic survey was used to delineate the basement structures which control the groundwater flow. The magnetic data were subjected to statistical and analytic signal analysis, where it showed clearly the complexity of the studied area. Resistivity profiling and sounding were used to investigate and ensure the potentiality of the groundwater occurrence in the structurally complex basement. Resistivity profiling was used to define the effect of the basement structures on the groundwater distribution. Vertical Electrical Sounding was conducted at selected sites along the magnetic and resistivity profiles. The integration of the obtained results from these two methods was successful to define the sites for drilling wells for the groundwater supply.
