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.

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

Three-dimensional slope stability analysis incorporating unsaturated soil properties in Singapore
Georisk: Assessment and Management of Risk for Engineered Systems and Geohazards, 2020 Rainfall-induced slope failure is a natural hazard that occurs in many parts of the world. To identify areas where rainfall-induced slope failure may potentially occur in Singapore, a slope susceptibility map of needs to be developed.

Cyclic behaviour of an unsaturated silty soil subjected to hydro-mechanical damage [PDF]
E3S Web of Conferences, 2020 The dynamic behaviour of unsaturated soil subjected to cyclic loading is considered using two stress state variables, net normal stress and matric suction. Though the influence of excess pore-water pressures in fully saturated soils has been investigated
