Role of Remote Sensing and GIS in Artificial Recharge of the Ground Water Aquifer in the Shanmuganadi Sub Watershed in the Cauvery River Basin, Trichirapalli District, Tamil Nadu

The importance of water is felt in all sectors as the demand and needs of the populace is growing. The present study area is basin of Shanmuganadi river lies between 10°56’ and 11° 7’North latitude and between 78°43’ and 78° 49’east longitude covered Trichirappalli district of Tamil Nadu. The basin area is demarcated from the survey of India Topographical maps were used, it covers an area about 93.25sq.km. The problem of the present study is a representative case of overexploitation of groundwater resources, leading to the continuous exhaustion of the grained as well as the ground water aquifers. The application of the increasingly and internationally accepted method of artificial recharge on the ground water aquifer was decided to be the most effective for the restoration of balance of the hydrogeological system. Deep knowledge of the details of the geological structure and the hydrogeological conditions of the area is necessary for the success of the method, whose planning has to be made based on the principles of environmental protection and sustainable development. Use of state-of-the-art technology and estimation of all the parameters involved, which are necessary, have been taken into account. Keeping this as an objective, to identify the suitable sites for artificial recharge zones an integrated approach of remote sensing and GIS approach techniques were used.
