Integrated remote sensing and GIS for groundwater exploration and identification of artificial recharge sites

Coupling distributed stormwater collection and managed aquifer recharge: Field application and implications

“…Field analyses provide valuable ground-truth for models evaluating locations for future MAR projects (Saraf and Choudhury, 1998;Jha et al, 2007;Yeh et al, 2009;Chenini et al, 2010;Rahman et al, 2012Rahman et al, , 2013Russo et al, 2014) and elucidate important site conditions that may not be represented in regional studies. We analyze the dynamics of, and relations between, precipitation, runoff generation, infiltration, and sediment transport at this site and discuss broader water resource management implications.…”

Delineation of Groundwater Potential Zones using Remote Sensing and GIS Techniques in Kanakanala Reservoir Subwatershed, Karnataka

“…A weight (1-9) represents the virtual importance of a parameter and the objective (Boobalan and Gurugnanam, 2016) which was given by Multi Influencing Factor (MIF). There is no standard scale for simple weighted overlay methods, for this purpose, criteria for the analysis are defined and each parameter was given its due importance (Saraf and Choudhury, 1998;Chaturvedi et al, 1983;Raj and Sinha, 1989;Baldev et al, 1991;Gustafsson, 1993;Krishnamurthy and Srinivas, 1995;Saraf et al,1997;1998;Shahid et al, 2000;Jasrotia et al, 2007a;Jasrotia et al, 2012b;Mandal, 2011;Sedhuraman et al, 2014 etc). The weights and rank have been given by considering the works carried out by Krishnamurthy et al, (1996), Dey (2014) and Waikar and Nilawar (2014).…”

Delineation of Suitable Zones for the Application of Managed Aquifer Recharge (MAR) in Coastal Aquifers Using Quantitative Parameters and the Analytical Hierarchy Process

“…Geophysical methods were also used to determine the optimum hydrogeological sites for placing recharge wells by linking electrical resistivity to aquifer permeability [14]. Saraf and Choudhury [15] used remote sensing and Geographical Information Systems (GIS) to overlay slope, geological, geomorphological, and lineament maps so as to determine a suitable site for recharge basins. The application was performed in a fissured rock aquifer in India, and remote sensing was used to map lineaments and link them with fault zones.…”
