Quantitative field-scale descriptions of chemical transport in the unsaturated (vadose) zone are essential for improving our basic understanding of the transport process in near-surface geologic environments and for sharpening the predictive tools that in turn will be used to predict the future spread of pollutants in these environments. The traditional approach to modeling transport processes in the vadose zone has been to model water flow and solute
transport by using the macroscopic physical and chemical properties of the soil that vary in a …
