Abstract:
Main intention of Geophysical resistrvity surveying is to interpret the subsurface
conditions for engineering applications. The earth exhibits a far from uniform structure
and therefore the surface resistivity varies from location to location as well as on seasonal
basis. Often, the structure will have resistivity layers related to the physical layers such as
topsoil, sub-soil, and bedrock. Clearly these layers or divisions in soil structure will have a
considerable impact on both soil resistivity and earth resistance/impedance. This
anisotropy found in platy structures will result in an apparent resistivity which with wide
variations.
