Numerical model for the determination of the soil retention curve from global characteristics obtained via a centrifuge [PDF]
, 2012 A novel centrifuge set-up for the study of unsaturated flow characteri\-stics in porous media is examined. In this set-up, simple boundary conditions can be used, but a free moving boundary between unsaturated-saturated flow arises.

A structural bounding surface constitutive model for unsaturated soils and its verification
Yantu gongcheng xuebao, 2022 Most soils have both unsaturated and structural properties. The establishment of a constitutive model of unsaturated soils considering the structure is of great significance for analyzing the mechanical properties of unsaturated soils.

Estimating Unsaturated Hydraulic Conductivity in Unsaturated Soil Using Soil Moisture Sensors
International Journal of Integrated Engineering, 2023 Unsaturated hydraulic conductivity (K) is a measurement of soil water-retaining ability in unsaturated soil. The unsaturated hydraulic properties are necessary to predict the movement of water in unsaturated soil. The current study aims to create an alternative experimental device to estimate theKusing soil moisturesensors. The experimental

A Numerical Model to Study the Response of Piles under Lateral Loading in Unsaturated Soils
Geosciences, 2021 The interaction between a laterally loaded pile and the surrounding soil is typically limited to the shallower soil layer. Often, this zone is above the water table and therefore the interaction takes place under unsaturated conditions.

Relationship between the matric suction and the shear strength in unsaturated soil
, 2020 To understand the shear strength properties for unsaturated soil with different matric suction values, a modified triaxial test device was used. The matric suction is considered an important contributor to unsaturated shear strength properties.
