Water becomes a scarce resource during the past two decades due to inappropriate exploitation and developmental activities. It becomes crucial at this stage for strategic planning to conserve the water resources so as to managewith the present and future requirements. Though, the Karur district of Tamil Nadu has got two important rivers such as Cauvery and Amaravathi flowing at the district border, few tanks, drainages and canals forming good surface water sources for recharge of hard rock aquifers, many blocks have been identified asover exploited /semi-critical as far as the groundwater resource is concerned. Hence, a detailed study has been conducted to understand the geological and hydrogeological properties of groundwater aquifers and their control over the natural recharge of Karur district, Tamil Nadu using geostatistical model in GIS. Through this model, suitable sites have been identified as well as pragmatic and suitable mechanisms have been suggested for artificial recharge of hard rock aquifers of Karur district.
Key words: Geostatistical Model, GIS, Artificial Recharge, Suitable sites and mechanisms, Hard rock aquifers of Karur district, Tamil Nadu.

Quantification of available surface water is one among the most important aspects of Water budgeting in the rapid changing climate and erratic rainfall conditions prevailing in India amidst the rapid human developmental activities. Though conventional methods are being employed for periodical estimation of existing surface water from water bodies, there is no standard Geospatial technology based simple methodology available for anytime-use by the planners and administrators. This research paper presents one such simple and accurate methodology for quantification of surface water from reservoirs and tanks using Remote Sensing and GIS techniques. The results obtained in this study have been evaluated with the published data. Thus, it forms a basic model to further strengthen and make it useful for the administrators in water resource budgeting and proper distribution of it for sustainable development of the society.
