Abstract
Horizontal contaminant transport through unsaturated soil has been demonstrated both analytically and experimentally. The water and solute transport equations were solved using the Boltzmann transformation, to convert the partial differential equations to ordinary differential equations. The resulting mathematical model was verified using experimental data. A laboratory scale soil column system was constructed and operated horizontally to monitor both the actual solute concentration profile and the development of the wetting front. Comparison between the predicted values and the experimental data has shown good agreement. Hence, the analytical solution can be used successfully to predict horizontal contaminant transport in initially dry soil.
