GEOPHYSICAL STUDIES - Introduction

In Madhya Pradesh, geophysical surveys for groundwater resource development were initiated by GSI/Exploratory Tubewell Organization, Govt of India, which is now CGWB, during early sixties through geophysical logging of exploratory boreholes. However, surface geophysical surveys started in systematic manner only since 1974 by CGWB onwards. During the initial stage, electrical resistivity method was the only technique in vogue and was utilized as a source finding technique. Gradually other techniques like electro-magnetic, seismic refraction, magnetic were also initiated. In the state, during 1976 a comprehensive geophysical study programme was started under Indo-British collaboration Betwa Project by applying electrical, electromagnetic, seismic, magnetic, gravity and geophysical logging methods. Presently, the CGWB is the apex organization for applying geophysical techniques for various applications in groundwater resources development.
