Abstract: In the semi-arid region, particularly in hard rock terrain, shallow aquifers are major source of potable groundwater. These aquifers are indiscriminately exploited to meet the growing demand of water for domestic, irrigation as well as industrial use. In order to achieve a sustainable development, it is essential not only to delineate the groundwater potential zone and but also suitable augmentation scheme which in turn requires delineation of feasible recharge zone. Such zones are conventionally delineated through the application of various indirect methods such as hydro-geomorphological, geological and geophysical, which many times are time consuming and uneconomical. A simple, efficient and cost-effective cross correlation based process which takes into consideration the study of aquifer response to rainfall is provided in the present invention to delineate groundwater recharge zone.
