VERTICAL ELECTRICAL SOUNDINGS FOR DELINEATION OF GROUNDWATER PROSPECT ZONE IN A CRYSTALLINE TERRAINS OF THE MUVATTUPUZHA RIVER BASIN, KERALA, INDIA
The Muvattupuzha basin is characterised by lateritic capping followed by weathered/fractured rock and hard bedrock consisting of Pre-Cambrian and Archean gneisses. Groundwater in the Muvattupuzha river basin occurs under water table conditions in latentes and semi-confined to confined conditions in fractured crystalline. Vertical Electrical Soundings (VES) were conducted in the four sub basins of the Muvattupuzha (Muvattupuzha, Kothamangalam, Kaliyar and Thodupuzha) and the results were analysed qualitatively and quantitatively using both geological and hydrogeological information so as to demarcate potential groundwater zone in the phreatic aquifer and a few promising zone for putting medium to deep bore wells. It is found that among four sub basins, a large area of the Muvattupuzha sub basin is characterised by good to moderate phreatic groundwater potential zone while the rest of the basin fall under the category of poor to moderate. Certain promising sounding stations are identified in the basin for tapping groundwater from the third and fourth layers by putting medium to deep bore wells.
