To seek the numerical solution to the contaminant transport problem in
a porous medium, numerous publications on this aspect have emerged du
ring the last three decades. Among them the finite difference method a
nd finite element method have been widely used in this process of solu
tion. 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 t
he finite difference method, the finite element method and its formula
tion for modelling contaminant transport problems are discussed in gre
at detail. Finally, a numerical example has been given to show how the
finite element method is applied to solve contaminant transport probl
ems in engineering practice.
