Identifying groundwater rechargeable zone is important for watershed development and resource management of a region. In this work various features such as geology, lineament density, slope, drainage density, soil, land use/cover and rainfall distribution of Uppar Odai (South), Amaravathy basin was studied in order to identify the areas that are expected to be suitable for future groundwater exploration in the study region. An integrated analysis of various parameters provides better estimate of subsurface characteristics from groundwater perspective. On the basis of different weights assigned to each factor, it was found that about 16%, of the total area has good prospects of groundwater, whereas approximately 23%of the area relatively feeble prospects. Results are useful for identify the suitable locations and to recommend suitable area for construction of water harvesting structures to augment the groundwater recharge.
