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.
