The development of the river system of the state was largely governed by tectonic evolution of the eastern Himalaya and western edges of the Bengal basin. It can be divided into nine physiographic provinces of which the Himalayas, the western plateaus, the northern and western alluvial fans and the Ganga delta are most important. West Bengal (88,752 km²) is the only Indian state that stretches from the Himalaya to the Bay of Bengal. The very good to good ground water potential zone occupied 18% (20158.89 acres) of the total study area. Finally assigning weighted based ground water recharge zone has been divided into four categories namely very good to good, good to moderate, moderate to moderately poor and moderately poor to poor. IRS-P6 LISS-IV satellite image, hydrological soil group, resource map and other data sets have been utilized to extract information for make out hydro geomorphic character of the study area. Remote sensing and GIS based methodology is developed and tested for the evaluation of the ground water resource. The present study has been taken for identified the ground water potential zone of Kansai-Tangai interfluves area. Integrated use of remote sensing and GIS can provide the appropriate platform for convergence of multi-disciplinary data for identify, artificial recharge purpose ground water potential zone. Ground water development and management strategy needs analysis of a large volume of multi-disciplinary data from various sources. The availability of this water is not unlimited therefore its use should be properly planed based on the understanding of the ground water behavior in order to ensure its sustainable use.
Ground water is the only source of purified drinking water in a certain layer under the earth.
