Abstract
To seek the numerical solution to the contaminant transport problem in a porous medium, numerous publications on this aspect have emerged during the last three decades. Among them the finite difference method and finite element method have been widely used in this process of solution. Thus, the finite difference method for dealing with contaminant transport problems in porous media is briefly outlined in this paper. Considering the certain advantages of the finite element method over the finite difference method, the finite element method and its formulation for modelling contaminant transport problems are discussed in great detail. Finally, a numerical example has been given to show how the finite element method is applied to solve contaminant transport problems in engineering practice.
