Geoelectric methods are used in exploration of groundwater resources in both shallow and deep regional aquifers. These methods are also applied in engineering geology and archeological investigations for the detection of caves, voids, caverns, fractured zones and metallic objects. More recently, these methods have been employed in environmental studies for detailed landfill exploration and detecting leaks from lined waste disposal sites.
Geoelectric techniques are described below/; Standard direct current (DC) resistivity. 2D/3D resistivity imaging. Continuous Vertical Electrical Soundings (CVES) Advanced frequency and Time Domain Electromagnetics (FDEM and TDEM)
