An understanding of the way that solutes are transported in mining or natural environments is essential to the development
of sound strategies for managing waste disposal. Research on miscible pollutant movement in unsaturated porous media is
carried out both experimentally and numerically. Results of numerical modelling are obtained by solving the groundwater
flow equation and the solute transport equation. The finite element method is employed and comparisons between
simulation results and experimental data are found in remarkable agreement.
