The cone penetration test in unsaturated silty sands

E3S Web of Conferences, 2016
Very little is known about how to interpret the cone penetration test (CPT) when performed in unsaturated soils. The few published studies on the CPT in unsaturated soils have focused on either clean sands or a silt.

Centrifuge modelling of rainfall-induced slope instability in sand and silty sand [PDF]

, 2017
Rainfall-induced instability in slopes is an important challenge around the world. This paper aims to provide a better understanding of the processes involved when modelling slopes in a geotechnical centrifuge by presenting data from tests with two types

Soil Loosening of Compacted Urban Tree Sites Using a Pneumatic Lance Injector: Quantifying Treatment Success Through Tree Morphology and Soil Structure Parameters via Terrestrial Laser Scanning

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Urban trees provide essential ecosystem services, but their growth and longevity are often limited by soil compaction. Although pneumatic lance injection (PLI) is increasingly promoted as a minimally invasive and efficient soil loosening technique, but robust scientific evidence for its long‐term effectiveness remains limited.

Yielding in the isotropic compression of Porto silty sand

, 2012
Analizirano je mesto popuščanja dobro zrnjavega meljnega peska s testi enakosmernega stiskanja in skenerjevim elektronskim mikroskopiranjem (SEM). Testi so izvedeni z natančnimi instrumenti, za notranje in zunanje meritve deformacij, in meritve hitrosti strižnega valovanja s pomočjo upogibnih elementov.

Optimising Sulphur Fertilisation in Ryegrass–White Clover Swards Reduces Leached Nitrate Nitrogen Losses, While Increasing Plant Yield and Nitrogen Off‐Take

Journal of Plant Nutrition and Soil Science, EarlyView.
The inclusion of sulphur at two inorganic nitrogen rates (0 and 150 kg N ha−1) improves plant productivity in a ryegrass–white clover sward and reduces nitrate‐N loss to groundwater in a free‐draining sandy loam soil. ABSTRACT Background Reducing nitrogen (N) losses to water, lessening reliance on inorganic fertiliser and maintaining agricultural ...

Soil Texture’s Hidden Influence: Decoding Plant Diversity Patterns in Arid Ecosystems

Soil Systems
Desert plant communities play a vital role in sustaining the stability of arid ecosystems; however, they demonstrate limited resilience to environmental changes. A critical aspect of understanding community assembly mechanisms is determining whether soil

Early deglaciation history of the southeastern Baffin Island shelf (Eastern Canadian Arctic Archipelago)

Journal of Quaternary Science, EarlyView.
ABSTRACT During the last glacial period, the Laurentide Ice Sheet (LIS) was the largest terrestrial ice sheet on Earth. Its evolution since the Last Glacial Maximum profoundly influenced Earth's geodynamics and surface processes. Investigating the past dynamics of the LIS provides critical insights into how contemporary ice sheets may respond to ...

Experimental study on critical state of unsaturated silty sand

Yantu gongcheng xuebao, 2018
The critical state of soil shows the end of its deformation process, which is very important for analysis and establishment of constitutive model for soil. The unsaturated silty sand is used in this study.

Proglacial lake records of Holocene glacier behaviour and catchment processes in Slettedalen, Northeast Greenland

Journal of Quaternary Science, EarlyView.
ABSTRACT Constraining Arctic catchment response to Holocene climate change is vital for understanding future environments. We present detailed sedimentological, geochemical and grain size end‐member analysis of two Holocene (~7.0 ka to present) lake sequences, S1 and S2, close to Zackenberg, Northeast Greenland.
