Temperature dependence of water retention curves for wettable and water-repellent soils
The capillary pressure (psi) in unsaturated porous media is known to be a function of temperature (T). Temperature affects the surface tension (sigma) of the pore water, but possibly also the angle of contact (gamma). Because information on the temperature dependence of gamma in porous media is rare...

Zusammenfassung: | The capillary pressure (psi) in unsaturated porous media is known to be a function of temperature (T). Temperature affects the surface tension (sigma) of the pore water, but possibly also the angle of contact (gamma). Because information on the temperature dependence of gamma in porous media is rare, we conducted experiments with three wettable soils and their hydrophobic counterparts. |
