IDENTIFICATION OF GROUND WATER POTENTIAL ZONE USING REMOTE SENSING AND GIS TECHNIQUES

The ground water is one of the important resources of natural water; ground water recharge potential zone to protect the water quality and to manage the ground water system. Using Geographic Information System (GIS) technology parameters like slope, geology, geomorphology, drainage density, land and land cover are obtained using top sheets. Vertical Electrical Soundings (VES) were conducted at 15 different locations at Channapatna Taluk. The fracture zones were available at 50, 90 and 100 feet depth in VES-7 at Kudluru. The depth at 50, 60 and 70 feet, fracture zones were also available and hence this area is considered as excellent zone in VES-10 at Sulleri. And below 200 feet depth, fracture zones were not observed which indicates the failure for the bore well in VES-15 at Sankalagere village.
