Some Thermodynamic Properties of Soil Water
Soil Science Society of America Journal, 1960Abstract The partial specific Gibbs free energy or moisture potential of soil water has been measured by methods that are widely accepted. There are several other thermodynamic properties that are of significance in soil moisture relationships that are not so readily measured and are not well understood.

Thermodynamics of freezing soil closed system saturated with gas and water
Cold Regions Science and Technology, 2020Abstract Natural eruptions in shallow permafrost with formation of large craters reported lately from gas-producing regions of the Russian Arctic may result from pressure buildup in freezing closed zones of gas-saturated unfrozen soil (taliks). Under certain conditions, increasing pressure may lead to hydraulic fracture of the overlying permafrost ...

A thermodynamic model for calculating the unfrozen water content of frozen soil
Cold Regions Science and Technology, 2020Abstract On the basis of thermodynamic principles, the relationship between freezing temperature depression and pore radius of soil has been derived. Combined with the soil pore size distribution, this paper proposes a thermodynamic model for calculating unfrozen water content, and investigates the effects of pore radius, nonfreezable layer, and pore

Water Adsorption by Dry Soil and Its Thermodynamic Functions
Soil Science Society of America Journal, 1964Abstract The adsorption of increments of water vapor on Millville loam soil was studied in an air‐free system. The resulting data included the amount of water that would condense on the soil at different relative humidities up to 90% at 14.8°, 24.8°, and 34.8°C.

Non-linear thermodynamics of soil-water-heat systems
Journal of Hydrology, 1970Abstract Evaluation of the second order phenomenological coefficients in soil-water-heat system as suggested by Srivastava and Abrol is examined and discrepancy there-in reported.

Thermodynamic state functions of the soil water system
Wärme- und Stoffübertragung, 1979The formalism of generalized thermodynamics is applied to moist soil, as a three phase system, to derive expressions for the thermodynamic functions of each phase in terms of well defined characteristic variables. While there is no special problem in assigning proper expressions to the thermodynamic functions of the solid and gas phases, the water ...

The soil–water characteristics curve (SWCC) that is typically measured from laboratory tests is fit using mathematical models that are based on capillary law and used along with the saturated soil properties for predicting the hydro-mechanical behavior of unsaturated soils. Such SWCC models are valid for coarse-grained soils.
