Hydrogeological Studies At Jalakandapuram Sub – Basin Of Sarabanga Minor Basin, Salem District,Tamil Nadu

The main objective of the present study is to investigate the hydrogeology of the Jalakandapuram sub – basin, groundwater potential and quality of groundwater for domestic, industrial and agricultural purposes. Jalakandapuram ( Latitudes 11° 35‟30‟‟N to 11°46‟25‟‟N and Longitudes 77°48‟30‟‟ E to 78°2‟E) Subbasin is one among the four subbasins of the Sarabanga minor basins which comes under the Cauvery basin. It has an areal extent of about 325 Sq.Kms. The study area has been studied with aerial Photographs (Block and white) prepared under UNDP Project (1971) and satellite Imageries (IRS IA – LISS II ). The base map of the Jalakandapuram sub – basin has been prepared from the topo sheets (1: 50,000 scale) 58 E/14, 58 E/13, 58 I/2 Published by the Geological Survey of India in the year 1972. The location of the study area, its accessibility, Physiography, climate, rainfall and vegetation are presented. to classify the groundwater of Jalakandapuram sub-basin. This was done using the 25 water samples that were collected by the author and analysed in the Soil Testing Laboratory, Salem – 1. Plots of water samples in the hydrogeochemical classification diagrams (Piper‟s, Handa‟s and USSL) throw light on the quality of groundwater within the study area.
