Centrifuge Modeling of Moisture Migration in Silty Soils

Abstract

An effort has been made to demonstrate use of a small geotechnical centrifuge as a research tool to understand moisture migration in a silty soil. Such a basic study is essential for understanding the much more complex phenomenon of solute transport through a soil, where the physical, chemical, and biological properties of the soil-solute system play an important role. Present study indicates that the advection in soils is dependent on the state of the soil and, in particular, on its degree of saturation. The effect of pore structure on the advection process has also been demonstrated. The trends of experimental data indicate that modeling of models may be valid only for saturated soils.
