Abstract:

Groundwater is a dynamic and replenishable natural resource, but in hard rock terrains, availability of groundwater is of limited extent and is depleting in many areas due to its large scale withdrawal for various sectors. Groundwater recharge such as rainwater harvesting is essential in order to improve ground water level and quality. The main objective of the study is to identify suitable sites for groundwater recharge in the study area through Geospatial technology. To attain this Remote Sensing Technology is the good tool in mapping such geological features related to groundwater recharge. The study area of Bhavnai watershed (4B2D1) of LBP basin has the area of around 712 km2. Groundwater recharge zones were identified via seven parameters adjoining with the emerging technology of Remote Sensing and GIS. The thematic layers were considered in this study are Geology, Geomorphology, rainfall, slope, lineament, soil and drainage which were prepared using the conventional data. All these themes and their individual features were then assigned weights according to their importance in groundwater recharge. The thematic layers were finally integrated to yield a groundwater potential zone map, As far as the groundwater potential zones are concerned 75 % of the study area falls in zones of moderate category, 18% falls in good zone and 7% under very good zone category.
