Reliability of Soil Water Characteristics Curve under Different Normal Stresses for Unsaturated Sand [PDF]

BIO Web of Conferences
The soil water characteristics curve (SWCC) demonstrates a link between soil moisture content and suction. The SWCC is almost treated as an index parameter in unsaturated soil. The soil permeability and shear strength can be linked to SWCC.

Hydro‐Mechanical Modelling of Gas Migration in Bentonite: Formulation and Laboratory‐Scale Validation

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Gas generation and migration in bentonite buffer materials are critical processes affecting the performance of deep geological repositories for radioactive waste. This study presents a new hydro‐mechanical formulation for simulating gas migration in saturated, compacted bentonite, with particular emphasis on the role of non‐uniform stress ...

Scaling of soil water retention and hydraulic conductivity curves (Brooks–Corey model)

Agrosystems, Geosciences &Environment, Volume 9, Issue 4, December 2026.
Abstract Scaling is a widely used technique in soil science to characterize the variability of water retention curves and hydraulic conductivity functions. This study aims to develop a method for scaling the water retention curve and hydraulic conductivity based on the Brooks–Corey equation using minimal field data.

Estimation of the Variation of Matric Suction with Respect to Depth in a Vertical Unsaturated Soil Trench Associated with Rainfall Infiltration

E3S Web of Conferences, 2016
Soil trenching is extensively used in geotechnical, mining, tunneling and geo-environmental infrastructures. Safe height and stand-up time are two key factors that are required for the rational design of soil trenches.

Permanent Deformation Characteristics of Beach Sand as a Subgrade Filler Integrating Dynamic Triaxial Testing and Machine Learning

Applied Research, Volume 5, Issue 5, October 2026.
Dynamic triaxial tests, field FBG monitoring, and machine‐learning analysis reveal that beach‐sand subgrade deformation is governed primarily by deviatoric stress and moisture. Fine sand deforms more than medium sand, while overload and wet‐side moisture deviation sharply amplify permanent deformation.

Predicting the Unsaturated Hydraulic Conductivity of Compacted Polyurethane–Clay Using the Filter Paper Method

Applied Sciences
Sanitary landfill covers are exposed to varying environmental conditions; hence, the state of the clay layer also changes from saturated to unsaturated. The study aimed to predict the unsaturated hydraulic conductivity of the locally available compacted ...

Ditch‐Buried Straw Return Improves Soil Physical Quality and Crop Biomass in Two Rice–Wheat Paddy Soil Systems

Land Degradation &Development, Volume 37, Issue 16, Page 11761-11776, October 2026.
ABSTRACT Ditch‐buried straw return (DB) is an innovative practice combining deep tillage and straw incorporation. This study aimed to evaluate its effects on soil physical quality compared to rotary tillage (RT) and identified key constraints to crop in sandy‐loam and clay‐loam paddy soils within rice–wheat systems. Two field experiments were conducted

Quantification of flash flood peaks using computer simulation for potential hill torrents of Pakistan: A modeling study

River, Volume 5, Issue 3, Page 432-452, August 2026.
Abstract This study investigates rainfall runoff behavior of five major torrential Nullahs' of Dera Ghazi Khan (D. G. Khan) for flash flood events. The integration, and fusion of satellite‐based meteorological, topographical, and pedo‐transferred function's (PTF) derived soil hydraulic datasets at 250 m grid size substantially proves a viable approach ...

Evaluation Model of Soil Water Characteristic Curve of Red Clay Based on Dielectric Theory [PDF]

长江科学院院报
[Objective] The soil water characteristic curve (SWCC) can effectively reflect the relationship between soil water suction (matric potential) and water content, yet conventional testing methods pose challenges for the calibration of in situ soil ...
