Abstract: In this study, the finite element methodology combined with random field theory was developed to analyze the influences due to the spatial nonuniformity of hydraulic conductivity. Monte Carlo technique was applied to obtain an approximate solution for two-dimensional steady flow in a stochastically defined nonuniform medium. The uncertainty in model prediction depends on both the spatial nonuniformity in hydraulic conductivity and the natures of the flow system such as water curtains and boundary conditions. Especially, we relate these uncertainties with well known gas tightness condition.
