Description: CRREL Report
Abstract: Empirically determined data on changes in unfrozen water content occurring as result of changes in the state of ice and water in soil are discussed with reference to the changes in soil-water retention data for ice-free soil. The similarity between the two types of data is developed. The Brooks and Corey, van Genuchten and Gardner equations are then shown to be applicable to describing unfrozen water content data. These three functions are then used in the model of Mualem and the relative hydraulic conductivity of frozen soil is predicted.
