First results on the direct detection of groundwater by seismoelectric effect ? A field experiment

Abstract

The successful application of conventional geophysical methods in exploring for groundwater and in solving hydrogeological problems has resulted in the refinement of the geophysical techniques used, as well as in the adoption of hitherto unused but known geophysical techniques for groundwater exploration. All these methods use the variation in a physical parameter as the guide for groundwater prospecting. Groundwater exploration by geophysical methods is still being commonly carried out by employing either electrical or seismic techniques. The advent of computer aided analysis of electrical field data facilitates the interpretation of subsurface geoelectrical parameters to desired accuracies. Under favourable conditions using seismic methods it is now possible to record water table associated signals. Induced polarization, VLF and other EM techniques are being used increasingly in exploring for groundwater.
