Three different methods are compared to each other and to the analytical solutions.
Analytical solutions are available only for simple systems.
The only techniques available for complex systems commonly found in many physical situations are numerical techniques. By their nature, numerical methods can introduce error into the solution. The objective of this project is to examine this error. The first method is our base method where our standard equation is solved in one step. Finally the third method, has each of the components solved separately, advection, dispersion, and reaction.
