Abstract
Within the framework of stochastic theory and the spectral perturbatio n techniques, three-dimensional dispersion in partially saturated soil s with a finite correlation scale of log-hydraulic conductivity is ana lyzed. The effects of spatial variability of the moisture distribution parameter on the asymptotic spreading behavior of a unsaturated solut e plume are assessed. This is accomplished by comparing two asymptotic macrodispersivities and two variance of solute concentration, obtaine d for a constant moisture content and spatially varied moisture, respe ctively.
