Adjusting the water retention curve for retractable soils
The soil water retention curve (SWRC) relates moisture to soil water retention energy (matrix potential). The calculation of the volumetric humidity considers the sample volume. In retractable soils, this volume varies according to the drying or wetting

Chemical migration during soil water retention curve evaluation [PDF]
Wetting and drying (W-D) cycles can induce important elemental migrations in soils. The main purpose of this work was to study the possible existence of soil chemical elemental migrations in samples submitted to repeated W-D cycles during evaluations of ...

Soil Water Thermodynamic to Unify Water Retention Curve by Pressure Plates and Tensiometer [PDF]
The pressure plate method is a standard method for measuring the pF curves, also called soil water retention curves, in a large soil moisture range from saturation to a dry state corresponding to a tension pressure of near 1500 kPa. However, the pressure

Order Out of Chaos in Soil–Water Retention Curves
Water flow in porous media is one of many phenomena in nature that can demonstrate both simple and complex behaviors. A soil–water retention curve (SWRC) is needed to characterize this flow properly. This curve relates the soil water content and the matric potential (or porepressure), being fundamental for simulating unsaturated soil behaviors.
