A numerical model for simulating flow and transport of contaminants with variable density in fractured porous media is presented. The non-linearities arising from the density variation and the velocty-dependent dispersion terms have been handled by Picard method. It is shown that the contaminant tra

β¦ Synopsis
Stochastic equations for the prediction of contaminant migration in porous media are considered by the use of the decomposition method. The results are easily generalized to the nonlinear case as well. Important applications of significance in the environmental sciences and engineering are beginning to appear in the literature, such as the forecasting of contaminant plume evolution in natural soils and aquifers after chemical spills, aquifer restoration, and groundwater pollution management.

Nonideal or nonequilibrium transport through porous media is described by a convection-diffusion equation coupled to a first order kinetics accounting for mass transfer between the solid and the fluid phases. The overall mathematical model may be formulated using an integro-differential approach and
A boundary element method is developed for the analysis of contaminant migration in porous media. The technique involves, "rstly, taking the Laplace transform with respect to time then followed by a co-ordinate transform and a mathematical transform of the well-known advection}dispersion equation.

In the second paper in the series, the boundary element method for analysing contaminant migration problems in homogeneous porous medium developed in the earlier paper by Leo and Booker is extended to the non-homogeneous porous media. This extension enables potential application in practical design
