【 摘 要 】

The objective of this study is to analyze flow and transport within the vadose zone during a midscale hydrologic infiltration experiment to characterize in-situ transport processes. This project will employ numerical and experimental tools developed under a previously funded EMSP proposal (project number 55332) to provide 3-D unsaturated hydrologic property distributions. In the present project, geophysical imaging techniques will be employed to track an analogue contaminant plume. The results will provide a better understanding of transport modes including the influence of natural heterogeneities and man-made structures within the vadose zone at DOE sites. In addition the data will provide checks against which numerical flow and transport simulations can be compared.
