A mathematical and numerical model is developed to simulate the transport and fate of NAPLs in near-surface granular soils. The resulting three-dimensional, three phase simulator is called NAPL. The simulator accommodates three mobile phases: water, NAPL and gas, as well as water- and gas-phase transport of NAPL contaminants. The numerical solution algorithm is based on a Hermite collocation finite element discretization. Particular attention has been paid to the development of a sub-model that describes three-phase hysteretic permeability-saturation-pressure (k-S-P) relationships, and that considers the potential entrapment of any fluid when it is displaced. In addition rate-limited dissolution and volatization mass transfer models have been included. The overall model has been tested for self-consistency using mass balance and temporal and spatial convergence analysis. The hysteretic k-S-P and mass exchange models have been tested against experimental results. Several example data sets are provided.
