A Two dimensional flow and transport model for tidally influenced aquifers

A 2D finite element model for predicting fate of soluble contaminants in confined or unconfined coastal aquifers has been developed, The influence of tidal effects on the groundwater flow and the pollutant transport process was a primary component ofthe model. The transport process modeling includes advection and dispersion. Attenuation mechanisms like adsorption and decay are not included in the model to make its estimates conservative. The main features ofthis model are its ability to represent the tidal boundary, and its capability of dealing with the nonlinearity resulting from variations in the saturated thickness in unconfined aquifers, and the new way of representing the general head boundary condition
