GROUNDWATER INVESTIGATION IN THE PIEDMONT ZONE OF HIMALAYAN FOOTHILL REGION, INDIA, USING ELECTRICAL RESISTIVITY TECHNIQUES

Abstract

Electrical resistivity, observations well and lithological data are used for thegroundwater investigation in the piedmont zone Ratmau –Pathri Rao watershed inHaridawre Districted of Uttaranchal India, The analysis of the resistivity data in thelight of known lithology indicates that two aquifer (shallow and deep) are generallypresent in the areaThe resistivity of aquifers are generally varies in wide range. This is due to thepresence of different size of ranges of grains condition consisting of fine sand andgravel (pebble) in the Tarai zone which further grade to coarser material (Boulder inthe Bhabhar zone)
