CENTRIFUGE PERMEAMETER FOR UNSATURATED SOILS II, DETERMINATION OF THE HYDRAULIC CHARACTERISTICS OF AN UNSATURATED CLAY (2010)

This paper presents the hydraulic characteristics of an unsaturated, compacted clay, including its soil-water retention curve SWRC and hydraulic conductivity function K function , determined using a new centrifuge permeameter developed at the University of Texas at Austin. A companion paper describes the apparatus, its instrumentation layout, and data reduction procedures. Three approaches are evaluated in this study to define the SWRC and K function of the compacted clay under both drying and wetting paths, by varying the inflow rate, the g level, or both.
