Chapter 8Heat Transport

In most cases soils are not completely isothermal throughout the soil profile and soil-fluid temperatures may be important in the evaluation of a problem. Mean soil surface temperatures fluctuate as was described in Section 5.7.3; however, several meters below the soil surface temperatures are determined by the geothermal gradient which is very small. Usually, we do not need to concern ourselves with soil temperatures when evaluating moisture movement, particularly at a depth below the zero inflection point. Heat transport is an important topic for near surface algid (freezing and thawing) soils and some arid cases when vapor flow may be important. In contamination cases, vapor flow is of increasing importance and knowledge ...
