Integrating X‐Ray Computed Tomography and Hydraulic Properties for Soil Quality Assessment Under Soil Compaction

Land Degradation &Development, EarlyView.
ABSTRACT Soil compaction poses a significant threat to soil quality and sustainability, necessitating advanced assessment methods. We hypothesized that incorporating x‐ray computed tomography (XCT)‐derived pore characteristics with hydraulic properties would significantly enhance the development of a soil quality index (SQI) under soil compaction ...

Effects of soil moisture content and installation method on ultimate bearing capacity of pile in unsaturated silty sand

Results in Engineering
The load-bearing capacity of a pile embedded in unsaturated soil depends mainly on the matric suction present in the soil. Changes in this parameter directly influence pile performance.

Vegetation Improves Hydro‐Mechanical Soil Resilience on Humid Tropical Slopes: Field Evidence for Sustainable Land Management

Land Degradation &Development, EarlyView.
ABSTRACT Landslides represent a recurring hazard in humid tropical regions, primarily driven by intense rainfall that weakens slope materials and reduces shear resistance. Vegetation is widely promoted as a nature‐based solution to improve near‐surface soil conditions; however, systematic field‐based hydro‐mechanical evidence from humid tropical ...

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

Land Degradation &Development, EarlyView.
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

Preliminary Analysis on Matric Suction for Barren Soil

IOP Conference Series: Materials Science and Engineering, 2016
Abstract Most research conducted on slope failures can broadly be attributed to the convergence of three factors, i.e. rainfall, steepness of slope, and soil geological profile. The mechanism of the failures is mainly due to the loss of matric suction of soils by rainwater.

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

River, EarlyView.
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 ...

‘From the Fields Into the Bars’: The Story of Israel's First Transgender Novel, The Cut (1977)

Gender &History, EarlyView.
ABSTRACT In 1977, an Israeli transgender woman, Judy Spotheim, published an autobiographical novel entitled The Cut. It describes the emergence of a trans community in the commercial‐sex areas of Tel Aviv‐Jaffa, hoping to humanise trans women (coccinelles). This article is the first to study the novel and present a biography of Spotheim.

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.

De‐Coupled Water and Nitrogen Translocation From Subsoil to Canopy of Temperate Forest Trees

Plant, Cell &Environment, EarlyView.
ABSTRACT Water and nitrogen (N) transport from soil to canopy play a central role in tree functioning, yet direct evidence for their timing and coupling in mature forests remains scarce. We report results from a paired dual‐isotope (2H, 15N) tracer experiment in a temperate forest, comparing water and nitrate uptake patterns across tree species ...

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.
