摘要：
The dispersion behavior of a substance in the ground water flow depends on the random field characteristics of the permeability. In this study, we clarify how the Gaussian and the non-Gaussian random fields of permeability affect the dispersion behavior. The non-Gaussian random field simulation method is newly proposed in this study. The finite difference method (FDM), combined with the Monte Carlo method (MCM), is used in the analysis to solve the advection and dispersion equations. Firstly, a tracer mixed with water is analyzed as a single-phase problem. Then, the migration of the DNAPL pool in the ground water is treated as a two-phase problem.
