Description
Summary:	The goal of the current study was to identify possible groundwater occurrence zones by combining the applications such as remote sensing, geographic information system and analytic hierarchy process techniques. In accordance with their impact on groundwater potential, various prepared thematic layers including lithology, geomorphology, rainfall, lineament density, land use and land cover, drainage density, soil type, slope, and soil texture were each given a weight. The results of this study are extremely positive, and the comprehensive methodology adopted has demonstrated its relevance in mapping groundwater potential areas in the drought-affected regions of Palani taluk. Have an opinion on how artificial structures may affect the vulnerability zones, and then map the artificial recharge structures for the study region of Palani taluk. Applying these methodologies, groundwater potential areas were identified, and they were divided into five zones: low, medium, medium-high, high, and very high potential. Very high favourable zones fall under value ranges beginning at 429.40, while low favourable zones fall under ranges beginning at 6.60. There is a total of 26 well locations used for observation and calculation of groundwater levels. Puliampatti has the highest groundwater level in Palani taluk 2.2 m·bgl, while Vagarai has the lowest groundwater level 10.88 m·bgl.
