Prediction of the Soil–Water Retention Curve of Loess Using the Pore Data from the Mercury Intrusion Technique [PDF]

, 2023
The soil–water characteristic curve (SWCC) is a crucial input parameter for describing the distribution of soil moisture and water movement in various environmental and geotechnical challenges. It is widely recognized that the SWCC is controlled by

Physical-statistical model for estimation of hysteresis of soil-water characteristic curve

Yantu gongcheng xuebao, 2023
The hysteresis phenomenon is commonly observed associated with both the soil-water characteristic curve (SWCC) and the hydraulic conductivity function (HCF) of unsaturated soils. In other words, the volumetric water content and the hydraulic conductivity

A methodological framework to determine optimum durations for the construction of soil water characteristic curves using centrifugation

Irish Journal of Agricultural and Food Research, 2016
During laboratory assessment of the soil water characteristic curve (SWCC), determining equilibrium at various pressures is challenging. This study establishes a methodological framework to identify appropriate experimental duration at each pressure step

The influence of suction changes on the stiffness of railway formation [PDF]

, 2011
Despite compacted soils being unsaturated, geotechnical design is predominantly based on saturated soils,despite it being known that differences exist between the behaviour of saturated and unsaturated soils.Suction in soils has been shown to increase ...

Uncertainty in the determination of soil hydraulic parameters and its influence on the performance of two hydrological models of different complexity [PDF]

, 2009
Data of soil hydraulic properties forms often a limiting factor in unsaturated zone modelling, especially at the larger scales. Investigations for the hydraulic characterization of soils are time-consuming and costly, and the accuracy of the results ...
