Experimental Study on Determining Unsaturated Property of Soil [PDF]

open access: yes, 1980
This paper deals with the experimental study of hydraulic properties of unsaturated soil. In treating unsaturated zone, a great deal more data are required than are required for the saturated zone, but these properties of soils must be known to apply the

Unsaturated hydraulic properties of vegetated soil under single and mixed planting conditions [PDF]

open access: yes, 2019
Effects of plant roots on changes of soil hydraulic properties, including soil water retention curves (SWRC) and soil hydraulic conductivity functions (SHCF), are not well understood, especially when soil is unsaturated and vegetated with multiple plant ...

A Simple Model for Estimating the Hydraulic Conductivity of Unsaturated Soil

open access: yesApplied Sciences
Describing the hydraulic conductivity of unsaturated soil is very important in predicting water transport. Most current models have complex forms and generally need to be calibrated by the measured unsaturated hydraulic conductivity curve. A simple model,

Relationship between Anisotropy in Soil Hydraulic Conductivity and Saturation

open access: yesVadose Zone Journal, 2014
Anisotropy in unsaturated hydraulic conductivity is saturation‐dependent. Accurate characterization of soil anisotropy is very important in simulating flow and contaminant transport (e.g., radioactive nuclides at the U.S.
