Abstract

A multiphase flow and transport numerical model was developed to study the leakage of light non aqueous phase liquids (LNAPL) into the vadose zone and the associated contamination of both the unsaturated and saturated zones. The model was used to provide a better tool for addressing the movement and spreading the NAPL phase and the resulting contamination in both the vadose zone and the saturated zone. In order to guide experimental design and field investigations, the model was used to evaluate the sensitivity of the results in various low and transport parameters. It was found that the NAPI, density and the capillary pressure parameters (van Genuehten parameters) increased the NAMI, spreading in one direction at the expense of the spreading in the other direction. The remaining soil, flow, and transport parameters affected the vertical and lateral spreading in a similar minor, Based on the results presented herein, il seems that the exponent in of the van Genuehten capillary pressure saturation relation is the most influential parameter.
