“…Numerically, finite difference and finite element methods are the common approaches implemented by researchers (Doussan et al, 1998;Kim, 2006;Kim et al, 2003;Malaguerra et al, 2013). Alternately, Laplace and Fourier transforms are normally used to analytically estimate solute transport in aquifers (Chen, 2010;Chen et al, 2012;Connell, 2007;Singh et al, 2012;Singh, 2013). Bessel function expansion and the Hankel transform have been found to be the most appropriate analytical techniques for problems formulated with equations expressed in polar and cylindrical coordinates (Massab o et al, 2006;Singh et al, 2010a).…”
