Abstract

A numerical method is presented that models the coupled flow of heat, water, and solutes as unsaturated
soil freezes. Input requires a general knowledge of the physical properties of the soil as well as the
initial water, temperature, and solute distributions. Soil surface temperature or the heat flux across the
soil surface drives the model. The method reproduces the observations of temperature and water movement
in two nonsaline field studies previously reported in the literature. The analysis shows that increasing
solutes can decrease frost heaving by reducing water flow to the ice lens. A method for measuring the
unsaturated hydraulic conductivity in frozen soil is proposed.
