Analytical reliability analysis of soil-water characteristic curve

E3S Web of Conferences, 2016
The Soil Water Characteristic Curve (SWCC), also known as the soil water-retention curve, is an important part of any constitutive relationship for unsaturated soils.

Bimodal SWCC and Bimodal PSD of Soils with Dual-Porosity Structure

Mathematical Problems in Engineering, 2022
The soil–water characteristic curve (SWCC) and pore-size distribution (PSD) are fundamental characteristics of soils that determine many physical and mechanical properties. Recent studies demonstrate that both SWCC and PSD sometimes exhibit a bimodal feature.

Effect of initial void ratio on the soil water characteristics of unsaturated soil at high suctions

Shuiwen dizhi gongcheng dizhi, 2022
In arid and semi-arid regions, such as in northwestern China, unsaturated soils at high suction or over a wide suction range are widespread in various geotechnical designs.

Frozen Soil Hydrological Processes and Their Effects: A Review and Synthesis

Reviews of Geophysics, Volume 64, Issue 1, March 2026.
Abstract Frozen soils, including seasonally frozen ground and permafrost, are rapidly changing under a warming climate, with cascading effects on water, energy, and carbon cycles. We synthesize recent advances in the physics, observation, and modeling of frozen‐soil hydrology, emphasizing freeze–thaw dynamics, infiltration regimes and preferential flow,

Effects of grain-size distribution and hysteresis on soil-water characteristic curve (SWCC)

, 2018
The relationship between water content and soil suction, referred to as the soil-water characteristic curve (SWCC), plays a central role in understanding the behaviour of an unsaturated soil.

Water-holding characteristics of weathered granite soils

Yantu gongcheng xuebao, 2018
By using the pressure plate technique and the vapor equilibrium method with saturated salt solution, the water-holding characteristics of a granite double-layer soil slope with different weathering degrees are studied.

Field Observations and Geotechnical Modeling of Dune Face Erosion During a Storm (Narrabeen Beach, Australia)

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 3, March 2026.
Abstract Quantifying dune face failure during storm wave conditions is critical for improving the predictive capability of coastal erosion models. However, most high‐resolution dune erosion observations used to validate these models were obtained from reduced‐scale laboratory experiments, raising questions about their applicability to field‐scale dunes.

Effect of Compaction Effort and Initial Conditions on the Unsaturated Properties of Red Clay Soils

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
In geotechnical engineering, the principle of saturated soil mechanics is used in the construction of structures. However, defining the constitutive unsaturated soil model requires significant laboratory testing, and directly measuring the parameters of the soil–water characteristic curve (SWCC) by the pressure plate test is time‐consuming.

Field Experiments of Rainfall‐Induced Weathered Granite Residual Soil Shallow Landslides

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
Affected by the extreme climate in recent years, the heavy rainfall has induced a large number of shallow landslides along roads in the granite residual land area in southeast China. Currently, the hydraulic response, evolution mechanism, and failure process of unsaturated granite residual soil landslides at the field scale are not well understood.

Indirect models for SWCC parameters: reducing prediction uncertainty with machine learning [PDF]

Computers and Geotechnics
The soil–water characteristic curve (SWCC) is crucial for modelling the transport of water and hazardous materials in the vadose zone. However, measuring SWCC is often cumbersome and time-consuming. This paper introduces indirect models that predict SWCC
