A study of convective-dispersion equation by isoparametric finite elements

The transport of pollutants in ground-water aquifers is studied by means of a mathematical model and presented here. The governing equation for the movement of impurities takes the form of a convective-dispersion equation which is solved numerically using isoparametric, quadrilateral finite element method. The mixed boundary conditions and irregular distribution of the nodes can be handled easily by the finite element technique. The calculations show that the numerical model could be used as an effective means to predict the distribution of contaminant and to shed light on the ground-water pollution control.
