Abstract

In this paper, we mathematically model contaminant flow in a two-dimensional domain of the Puget Sound using a finite element numerical solution to the advection-diffusion equation coupled with a finite difference numerical solution to the Navier-Stokes equations. We offer two models of contaminant flow in this domain, the first uses a Gaussian point source model of contaminant flow. The second model utilizes a Gaussian point source and a constant boundary source. We offer a graphical presentation of both models and we also provide convergence testing of our numerical results at the final time-step. When we test for convergence of our numerical results, we find that our models are converging to an analytic solution at the final time-step. We also perform a graphical and numerical sensitivity analysis of our models and find that our numerical solutions to both our models are insensitive to small changes in the diffusivity parameter.
