Numerical Simulation of Contaminant Transport in Porous Soil

Solute transport in porous soils has been the topic of experimental, theoretical research and numerical simulation aspects. The complexity of the phenomenon of transport of pollutants in porous soil has to be faced in the most complete way. The contaminant transport processes in porous soils are simulated numerically based on overlap principle for a transient contaminant resource. The influences of duration and concentration of contaminant resource and dispersion coefficient of contaminant on contaminant transport processes are investigated numerically. The computation results show that the duration and concentration of contaminant resource can distinctly affect contaminant distribution and dispersion coefficient of contaminant has a small contribution.
