The water present in the subsurface is considered as a high treasured water source. The present study deals with the delineation of groundwater potential zone in Tirunelveli Taluk, Tamil Nadu, South India. The study area lies between longitude 77°32 0 16 00 to 77°48 0 8 00 E and latitude 8°40 0 12 00 to 8°56 0 34 00 N with an area of 558.42 km 2. The groundwater potential zone of the Tirunelveli Taluk was inferred by the following layers, namely geology, geomorphology, lineament density, drainage density, rainfall, slope, soil and land use/land cover. These layers are digitized with the scale of 1:50,000 in GIS environment from the spatial data sources such as SOI topographic maps, GSI geology map, LANDSAT 8 satellite image, SRTM DEM, Tamil Nadu Agricultural Department daily rainfall data and available existing maps. The weights of the feature layers and ranking of each feature classes arrive from the pairwise comparison techniques of AHP technique. The prepared thematic maps are reclassified based on the influence of the layers feature classes on the groundwater availability. Finally, the reclassified layers are overlaid using weighted overlay tool to prepare groundwater prospect map. The finally this study resulted that 5.76 km 2 of the study area is identified as very high groundwater potential. The high potential area covers 382.9 km 2 , and medium potential zone covers 169.72 km 2 .
In this study, an effort has been made to locate the subsurface basin for groundwater storage and to identify the suitable destination for the sustainable domestic, agricultural, and drinking needs to demarcate groundwater potential zones (GWPZ) for Srivaikundam region in Thoothukudi district, Tamil Nadu, India, using remote sensing and geographical information system (GIS) with analytical hierarchy process (AHP).

The study aims to demarcate groundwater potential zones in the Coimbatore district of South India using geographic information system (GIS), remote sensing (RS), and multi-criteria decision analysis (MCDA) methods. A total of 10 thematic layers such as geomorphology, geology, lineament density, land use/land cover (LULC), soil, drainage density, rainfall, slope, curvature and topographic wetness index (TWI) were created and analysed for groundwater potential zone delineation. The analytical hierarchal process (AHP) was employed to assign suitable weights to various thematic maps. The Weighted sum overlay analysis tool of ArcGIS 10.5 was used to overlay the thematic layers to generate the study area's groundwater potential zone (GWPZ) map. The resulting map was categorised into excellent, good, moderate, and poor. The findings indicate that about 16% and 37% of the study area is classified as poor and moderate groundwater potential zones, respectively, while approximately 26% and 21% fall under the good and excellent potential zones. The obtained results were validated using pre-and post-monsoon groundwater fluctuation data, which demonstrated consistency with the methodology adopted. Overall results prove the efficacy of using geospatial technology in combination with AHP in delineating groundwater potential zones. Hence, the results obtained can be helpful for decision-makers in the planning and management of groundwater resources and for locating the sites for new borewells in the study area.

Due to the indiscriminate use of limited water sources, the requirement for groundwater evaluation in India expanded substantially. Population growth and unequal distribution, poor irrigation systems, rapid urbanization/ industrialization, large-scale deforestation, droughts, and inefficient land use practises contribute to groundwater depletion.As a result, the need for water for agriculture, domestic, and industry soars. The study identifies viable zones in Visakhapatnam's emerging metropolitan metropolis by utilising the Analytical Hierarchy Process (AHP) approach with remote sensing data in ArcGIS software. Thematic layers were created by taking remote sensing data into consideration (drainage density, soil, lineament density, land use land cover, geomorphology, rainfall, slope, and geology). The method is employed to determine the weights of distinct thematic layers by obtaining the normalised weight from a pairwise matrix.To emphasize the groundwater potential zones and create a map with different zones specified, the weights and ranks extrapolated from the AHP approach have been made available in the weighted index overlay analysis tool in ArcGIS.Groundwater availability and recharge are significantly high in the good zone of the present study's four classifications of good, moderate, low, and very low. The groundwater status, potential locations for water extraction, and best practises for groundwater recharging may all be determined with the use of the acquired information from the indication map.
