Soil-water characteristic curve and permeability of hydrate-bearing soils

Yantu gongcheng xuebao, 2023
Understanding the soil-water characteristic curve (SWCC) and permeability of hydrate-bearing soils plays a critical role in analyzing the production efficiency and layer stability during hydrate exploitation. Based on the self-improved apparatus, hydrate

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,

Predicting the soil-water characteristic curve from soil particle size distribution considering the film water

Shui kexue jinzhan, 2017
Predicting soil water characteristic curve (SWCC) from particle size distribution was an easy, rapid and economical method. However, the traditional estimate of water content in this method didn't consider the adsorbed water films, which led to an ...

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.

A NEW EQUATION FOR SIMULATING SOIL WATER CHARACTERISTIC CURVE [PDF]

Journal of Soil Sciences and Agricultural Engineering, 2007
Several mathematical equations have been proposed to simulate soil water characteristic curve (SWCC).   All the equations show reasonable fit with measured data through a specified range of suction and in a specific soil texture, but this is not the case

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.

Effects of Long‐Duration Rainfall on the Stability of High and Steep Waste Dump Slopes

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
High bench dumping process makes the dump presents a trendy of high and steep slope, and rainfall is an important cause of inducing high and steep slope to slide. Especially under continuous rainfall conditions, the seepage law and stability evolution during the rainfall process of waste dumping sites with slope heights exceeding 200 m should be given ...

Soil–Water Retention Characteristics and Plant‐Available Water of Andosols in a Semiarid Environment: Evidence From the Central Rift Valley, Ethiopia

Applied and Environmental Soil Science, Volume 2026, Issue 1, 2026.
Soil–water retention characteristics and plant‐available water (PAW) are critical for irrigation management in semiarid Andosols. This study determined the soil–water characteristic curves (SWCCs) of Andosols at the Melkassa Agricultural Research Center (MARC), Central Rift Valley (CRV), Ethiopia, using a pressure plate apparatus at matric potentials ...

Moisture Migration Law and Stability Analysis of Fissured Loess Cave Dwellings Subjected to Rainfall

Geofluids, Volume 2026, Issue 1, 2026.
Loess cave dwellings are representative traditional earthen structures widely distributed in northwest China. Fissures extensively developed in loess can act both as structural weakness planes and as preferential pathways for rainfall infiltration. As a result, rainfall infiltration may readily induce instability in loess cave dwellings.
