“…In order to implement artificial groundwater recharge, it is essential to delineate potential groundwater recharge zones. Conventionally piston-flow model (Zimmermann et al, 1967;Munnich, 1968;Gupta and Sharma, 1984;Athavale et al, 1992;Rangarajan and Athavale, 2000;Chaulya, 2004;Chand et al, 2005;Mondal et al, 2009;Rangarajan et al, 2009;Samadder et al, 2011), remote sensing (Saraf et al, 2004;Chowdary et al, 2009;Elewa and Qaddah, 2011), photogeological (Salama et al, 1994;Jackson, 2002), hydrogeological (Fetter, 2001;Scanlon et al, 2002;Nonner, 2006;Kumar et al, 2011) and geophysical methods (Shankar and Mohan, 2005;Maliva et al, 2009), 14 C-age dating (Bredenkamp and Vogel, 1970), entropy method (Mondal and Singh, 2010) and regional groundwater models (Sibanda et al, 2009) have been deployed to select favorable sites for implementation of artificial recharge schemes.…”
