Methods of Soil Water Collection at Different Matric Suctions
To investigate the transport mechanism of solutes in soil water in the unsaturated zone, collection of soil water samples having different matric potential is necessary. Three methods originally developed for the purpose of measuring matric suction, i. e., the centrifuging, the pressure membrane, and the vapor pressure depression methods, were used to ...

Analytical calculation of steady seepage in unsaturated layered soils
The analytical calculations of unsaturated steady-state seepage in the widespread layered soils wewre relatively rare. Based on the Darcy seepage theorem and the continuity condition of soil layer interface, a mathematical model describing the steady ...

Governing failure mode of unsaturated soil slopes under rainwater infiltration
Due to rainwater infiltration and loss of matric suction above the wetting font, both translational and rotational slips may occur in an unsaturated soil slope. It is useful to know which failure mode is more critical.
