Abstract: Evaluation of availability of groundwater, its present use and balance assets for subsequent usage are the main elements of sustainable development and management of ground water assets. To meet of the requirement of the population family and industrial needs had the demand of water resources is sustainly expanding to keep up the food security. Based on the results obtained by the analysis in the study, the tentative sites for construction of recharge structures such as percolation tanks, check dams, farm ponds, and the de-siltation of tanks have also been suggested. But the field investigation is inevitable before implementing any water-harvesting program. Further, the groundwater resource estimation has to be taken up at the regular intervals to know the net balance available for future use. The sub-basin wise groundwater resource estimation has also been carried out to prioritise the sub-basins for taking up the artificial recharge structures. Further, based on the suitable zones for artificial groundwater recharge and the prioritisation of the sub-basins, few sites have been tentatively located for taking up artificial recharge structures. Various thematic sheets have been produced based on “Groundwater Estimation Committee-1997 method and assessed the groundwater resource and groundwater balance. The layers generated from the satellite data (IRS ID LISS III) and from the field data have been used for the index overlay operations for delineation of Groundwater prospective zones as well as for delineating the suitable zones for artificial groundwater recharge structures.
Keywords: Groundwater Resource, Groundwater Balance, Artificial Groundwater Recharge.
