چکیده:

In this study, a numerical method is developed to predict saltwater intrusion in to an unconfined coastal aquifer due to sea level rise as a part of climate change impact. The cell-centered finitevolume method is adapted to solve the set of coupled nonlinear partial differential equations whichdescribing the motion of seawater and freshwater separated by a sharp interface. A rectangular numerical grid was used and TDMA approach is also implemented to solve the matrix of discrete terms. The model is first verified by two known case studies and then applied to explore thesensitivity of the intrusion mechanism to various involved parameters. Finally we raised the seaside saltwater head of sample case and the toe of new time dependent salt wedge is determined and discussed.
