Abstract: Over the past several years, the results of many laboratory studies assessing the effect of various combinations of organic and inorganic chemical mixtures on the hydraulic conductivity of clays have been published. Although these studies have increased our knowledge and awareness of the potential effects of waste/soil interactions, there has been little emphasis on the development of predictive models to describe the transient change in the hydraulic conductivity. This paper treats the clay/leachate hydraulic test experiment as a dynamic physical-chemical interaction process and attempts to lay the framework within which the modeling of variations in soil flow characteristics may be undertaken.
