Abstract :
— The application of Geophysical Electrical
Resistivity methods by means of Vertical Electrical
Soundings for deciphering the subsurface characteristics of
Hard rock terrains has been attempted in the Ongur River
Sub Basin, Tamil Nadu. 77 Vertical Electrical Sounding
(VES) were conducted at regular station intervals. The
VES data were interpreted by Curve Matching Technique
using Standard Master Curves as well as ‘IPI2Win’
software. The interpreted VES results coupled with Hydro
geological data have been used to delineate subsurface
geological formations and ground water potential zone,
which will help in identifying areas suitable for
groundwater management in Hard rock terrains.
