5-Instrumentation for ground water exploration using electromagnetic techniques

Abstract

Electromagnetic techniques are widely used in different countries for solving diverse geological problems, mainly, soil profiling, geophysical prospecting and determination of water resources, The paper describes the development of an Inductive Electromagnetic system and methodology used for determination of water table depths in different geological environments in the country. Electromagnetic signals transmitted from the system through the earth are received at a specified distance and are linearly proportional to the conductivity of the media. The variations in conductivity with change in distance between the transmitter and receiver, provides the related information about water table depth in the terrain.
