Abstract
Contamination of groundwater by Nonaquoeus-Phase Liquids is a serious environmental problem; because the resulted plumes could be quite diffusive and widespread. Leaking underground storage tanks or accidental surface spills can leave a residual product trapped within the subsurface, often taking decades or longer to dissolve.
This paper presents the mathematical development of a numerical model that simulates a two phase flow (water-NAPL) based on a two dimensional finite element formulation. The model is posed in terms of water saturation and fluid pressure. It uses two phase capillary pressure and relative permeability to permit simulation in the saturated zone.
