Hydraulic and mechanical properties of glacial sediments beneath Unteraargletscher, Switzerland: implications for glacier basal motion [PDF]

, 2001
The force on a ‘ploughmeter’ and subglacial water pressure have been measured in the same borehole at Unteraargletscher, Switzerland, in order to investigate ice–sediment coupling and the motion at the base of a soft-bedded glacier.

Influence of salinity and water content on soil microorganisms

International Soil and Water Conservation Research, 2015
Salinization is one of the most serious land degradation problems facing world. Salinity results in poor plant growth and low soil microbial activity due to osmotic stress and toxic ions.

Hydrodynamic Process of Partial and en Masse Dam Failure Induced Debris Flows

Frontiers in Environmental Science, 2022
Because of landslides, seismic events, and/or unregulated human activities, a massive amount of loose solid materials are sometimes deposited at the confluence between the branch valley and stem stream, or blocked at the lateral channel contraction ...

Comparisons between sediment transport models and observations made in wave and current flows above plane beds [PDF]

, 1997
As a part of the MAST2 G8-M Coastal Morphodynamics project, the predictions of four sediment transport models have been compared with detailed laboratory data sets obtained in the bottom boundary layer beneath regular waves, asymmetrical waves, and ...

Integrated biogeography of planktonic and sedimentary bacterial communities in the Yangtze River

Microbiome, 2018
Background Bacterial communities are essential to the biogeochemical cycle in riverine ecosystems. However, little is presently known about the integrated biogeography of planktonic and sedimentary bacterial communities in large rivers.

Controls on Cyclic Formation of Quaternary Early Diagenetic Dolomite

Geophysical Research Letters, 2018
The origin of sedimentary dolomite and the factors that control its formation within the geological record remain speculative. In most models, dolomite formation is linked to evaporative conditions, high water temperature, increasing Mg/Ca ratio ...
