Groundwater harvesting and artificial recharge site identification on upper Shilabati watershed using geospatial approaches.

Rainwater harvesting and artificial recharge are substitute procedures to enhance groundwater and surface water for providing an unceasing water supply to a demand area. This analysis recommends the methodology to demarcate harvesting of rainwater and artificial recharge sites as recognizing constructive artificial recharge sites applying multi-criteria decision analysis (MCDA), integrated with remote sensing (RS), and GIS, procedures for supplementing groundwater properties in the Upper Shilabati catchment of West Bengal state, India. The Upper Shilabati catchment is a drought-prone area with high water demand to fulfill sustainable livelihood. The categorized regions like very low 5% (83.05 km2), low 32% (523.44 km2), moderate 26% (425.93 km2), high 37% (604.70 km2), and very high 0.002% (0.04 km2) while harvesting of rainwater regions are very low 6% (97.49 km2), low 25% (404.43 km2), moderate 53% (866.53 km2), high 13% (212.09 km2), and very high 4% (64.420 km2). The examining outcome indicates that the projected and previously current artificial recharge construction, like Percolation Tanks (PT), Check Dams (CD), Nala Bund (NB), Farm Ponds (FP), and Bore Wells (BW) with the entire numbers of 5, 2, 2, 2, and 1 similarly. The zones delineated for generating numerous artificial recharge structures with 112 artificial recharge constructions are notified, and 60 artificial recharge locations fall in the high recharge region. This artificial recharge is located in 28 (moderate recharge) and 24 sites (low recharge). Study outcomes could be applied to communicate an effectual groundwater management plan for domestic and agricultural determinations with confirm sustainable water supply for this basin.
