Abstract

The current study uses geospatial technologies to identify prospective artificial recharge sites in the Pulampatty sub-basin, Dharmapuri District in South India. Due to the population explosion, the district’s demand for fresh water is rising quickly. In addition, the district occasionally faces water stress situations due to a lack of surface water supplies and seasonal precipitation. To combat this, we can choose artificial groundwater replenishment over preexisting sources. To do this, we must determine the groundwater level in the targeted area at various points, while government agencies’ statistical data on the area’s average rainfall and precipitation levels provide us with an overview of the groundwater table. In general, the study area has a moderate groundwater table with fluctuations brought on by insufficient rainfall and excessive groundwater use. This will have an impact on the region’s agriculture and domestic needs, as well as the quality of the groundwater, which can be assessed by collecting water samples and analyzing the chemical content of the groundwater using a variety of chemical tests in a water quality analysis laboratory, then comparing the results to the corresponding optimal levels. To meet the region’s needs for drinking water, it is essential to manage the groundwater resources that are already available. Using a weighted linear combination method, important thematic layers such as lineament, slope, drainage, land use/land cover, lithology, geomorphology, and soil properties were merged. The properties of rocks were determined by conducting a geophysical survey using a resistivity meter, meantime the geology, geomorphology and lineament were determined by the GIS tool from the satellite data and maps. The study’s findings indicate that about 25% of the research region has high to moderate groundwater recharge potential. However, groundwater exploitation must be done in conjunction with artificial recharging to ensure the long-term sustainability of water supplies.
