Abstract

This paper focuses on the issue of two-dimensional hydrodynamic dispersion of soluble pollutants in soils and by doing indoor tests, some meaningful results are obtained: (1) When the void ratio is the same and the hydraulic gradient is similar, the dispersion rate of pollutants in the heterogeneous soil is much faster than that in the homogeneous soil; (2) In both homogeneous and heterogeneous soils, the longitudinal dispersion coefficient and the transverse dispersion coefficient are both linearly related to the flow velocity; (3) The heterogeneity of material can amplify the scale effect of dispersivity.
