摘要

A new method was developed to predict the transport of moisture and contaminants in soils. Study results indicate that this method could help simplify evaluation of municipal and industrial waste disposal sites for their potential environmental impact. Saturated and unsaturated hydraulic conductivities of several Illinois soils, calculated on the basis of pore size distribution, were shown to predict reliably the experimentally measured laboratory values. For coarse-textured soil materials and materials with a relatively narrow range of pore size, only one matching factor was required to calculate the hydraulic conductivity-water content relation accurately enough for many purposes; however, for fine-textured soil materials with a wide range of pore size distribution, two or more matching factors at a water content in the 0.3 to 0.4 bar range may be needed to obtain a useful evaluation for the unsaturated hydraulic conductivity.
