“…The study of water in aquifers and the characterization of aquifers are key topics of Hydrogeology, a discipline concerned with groundwater research. Stream/ tide-aquifer interaction, ''groundwater flow'' in aquifers, aquifer overexploitation, and climate change impacts on aquifers have remained hot research fields (Loáiciga et al, 2000;Custodio, 2002;Nastev et al, 2005;Intaraprasong and Zhan, 2009;Singh and Jha, 2011). Numerical simulation of ''groundwater flow'' and related contaminants and heat transport have attracted increasing attention during the past two decades.…”
