Abstract

Transport and contaminant discharge Simulation from coastal aquifers into seaward is complex due to boundary condition in seaward. In this research, ModSharp, a numerical model has been developed that is able to simulate contaminants transport in large scale in coastal aquifers. This model solves Advection-Dispersion equation with method of characteristics. The accuracy of the model was evaluated for several idealized problems for which analytical and numerical solution, in field of seawater intrusion and contaminant transport could be obtained. Effect of seawater intrusion on contaminants transport in coastal aquifers was simulated. Simulation results show that seawater intrusion has significant effect on solute transport in coastal aquifers. Neglecting the influence of seawater intrusion leads to a lower estimate for rate of contaminant discharge to sea.
