REMOTE SENSING AND GIS BASED APPROACH FOR DELINEATION OF ARTIFICIAL RECHARGE SITES IN PALANI TALUK, DINDIGUL DISTRICT, TAMILNADU, INDIA

Now a day's surface water was not enough for irrigation, industrial and basic household needs, so men decide to use groundwater to match the daily requirements. The economy of a country indirectly or directly related to groundwater resources. In India, groundwater extraction is more when compared to past two decades. In India, especially in Tamilnadu the farmers mainly depended upon ground water during the non-monsoon season, moreover, during the monsoon season, more rain water was lost through runoff. In Palani Taluk, Dindigul District groundwater level is in poor condition. Identification of the artificial recharge zone is such a good remedy to increase the groundwater level. With the help of remote sensing and GIS tools, we can distinguish our study area as excellent, moderate, good and poor artificial recharge zone.
