Evaluation of Methods for Calculating Soil Thermal Conductivity
A detailed analysis of methods for calculating the thermal conductivity of soils is presented, and trends in the predictions of these methods are compared. The influence of changes in the moisture content on the calculated thermal conductivity of a soil (at constant dry density) is shown as is the s...
