| Abstract | ||||
| A multiphase flow and transport numerical model is developed to study the leakage of light non Luscious phase liquids (LNAPL) into the vadose zone and the associated core lamination of both the unsuluruled and saturated zones, the model is fixed to provide a better look for addressing the movement and spreading of the NAPL please and the resulting contamination in both the vadose zone and the saturated zone. In order to guide experimental design and field investigations, the model is used to evaluate the sensitivity of the results to various low and transport parameters. It is found that the NAPL density and the capillary pressure parameters (van Genuehten parameters) increase the NAPL spreading in one direction at the expense of the spreading in the other direction. The remaining soil, flow, and transport parameters affect the vertical and lateral spreading in a similar manner. Based on the results presented herein, it seems that the exponent of the van Genuchten capillary pressure-saturation relationship is the most influential parameters. | ||||
