Abstract
The present study focused on the groundwater assessment for Nandani watershed using remote sensing and GIS techniques. The Nandani watershed has covered an area of 492 km2. For this study, all the satellite data is obtained from Bhuvan website and analyzed in ArcGIS software. The groundwater potential zones have been delineated using remote sensing and GIS techniques. About 48% area comes under high potential zone, 43% area comes under moderate potential zone and 9% area comes under poor and very poor potential zone. The preparation of different thematic layers such as lithology, slope, land-use, lineament, drainage, soil, and rainfall is facilitated by employing Survey of India toposheets and LISS III satellite images. These diverse factors are converted into raster data through the utilization of the feature to raster converter tool within the ArcGIS software. To assign significance, raster maps representing these factors are given predetermined scores and weights, calculated using the multi influencing factor (MIF) technique. The resulting output holds significant utility in promoting effective watershed development and water resource planning.
