SUB SURFACE INVESTIGATION USING ELECTRICAL RESISTIVITY METHOD – A CASE STUDY FROM SRM INSTITUTION, RAMAPURAM, CHENNAI (T.N), INDIA

Abstract

The geophysical investigation is a fundamental study  to  illustrate the physical characteristics  of the sub surface within the chosen sites. The study  includes  sub  surface  investigation  using vertical electrical sounding (VES) by Schlumberger configuration in SRM Institution, Ramapuram, Chennai. The significance of the study is to  assess the thickness of  the  aquifer and sub surface layers to evaluate their hydraulic characteristics. The  study  area  is  located  at Chennai, Tamilnadu, India. The total extent of the campus  is  about  16  acres.  It  is  located between North Latitudes 13° 02' 03.66"N and 13° 01'  53.89"N and between East Longitudes 80° 10' 37.22" E and 80° 10' 53.84" E. The objective of the investigation is to identify the sub surface layers for further study of finding suitable locations of groundwater potential for pumping and recharge.
