Role of Remote Sensing and GIS in artificial recharge of the ground water aquifer in Ottapidaram taluk, Tuticorin district, South India

The world population is expected to double by the middle of the next century, to about 10.6 billion people. More than 80% of these people will live in what is presently known as the "Third World." The importance of water is felt in all sectors as the demand and needs of the populace is growing. The present study area is Ottapidaram Taluk, Tuticorin District, Tamil Nadu and India. The Taluk boundary is demarcated from the survey of India Taluk maps were used, it covers an area about 743.62 km2. The problem of the present study is a representative case of over exploitation of groundwater resources, leading to the continuous exhaustion of the grained as well as the groundwater aquifers. The application of the increasingly and internationally accepted method of artificial recharge on the groundwater 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. Keep this as an objective to identify the suitable sites for artificial recharge zones.
