The product is responsible for capture the behavior of two legacy Fortran simulations. The first simulation models groundwater flow and containment transportation in two dimensions. The second simulation models the same, but in three dimensions. We fill first implement the two dimensional model, and after completing this portion of the program we will move on to implementing the three dimensional calculations. The product is also meant to expand on the utility of the legacy Fortran simulations. To do this, it we will convert the existing code base to Python and incorporate a graphical user interface. These actions are meant to accomplish two goals. The first goal is to allow the application to be run on a wider array of devices. The second goal is to improve user experience by including a graphical method for specifying inputs and viewing outputs.
