Computer evaluation of thermal and transport properties of unsaturated soils.

Author(s) : TARNAWSKI V. R., WAGNER B.

Summary

The paper describes an extended and modified version of the De Vries model for predicting thermal and hydraulic properties of soils having log-normal grain size distribution. The extended model predicts soil thermal conductivity, specific heat and soil hydraulic properties in a full range of moisture content (from dryness to saturation) and a temperature range from -30 to 95 deg C. The user may select a desirable unit system (SI, USCS, cgs) and a way of declaring soil moisture content (volumetric or mass basis). Testing results gathered to date suggest that this model works well for most coarse- and many medium-textured soils, but the predictions for fine-textured and most structured soils could in some cases be questionable.
