Assessing the importance of river bank erosion for fine sediment delivery to Bassenthwaite Lake [PDF]

open access: yes, 2007
Available evidence from lake sediment core records and short-term sediment flux sampling programs has suggested increased fine sediment deposition and suspended sediment transfers to Bassenthwaite Lake, Cumbria, U.K over recent decades. This increase in

Longitudinal Recovery of Suspended Sediment Downstream of Large Dams in the US

open access: yesWater Resources Research
Dams disrupt the natural flow of water and sediment along rivers. Reservoirs trap a significant amount of sediment, which substantially alters downstream hydrology, channel morphology, and sediment transport capacity.

Decreasing Suspended Sediment Concentration and Flux in the Bohai Sea: Based on Remote Sensing and Numerical Simulation

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
The Bohai Sea is the region with the highest suspended sediment concentration (SSC) in the world. The transport of suspended sediment from the Bohai Sea to the open sea greatly affects the coastal biogeochemical processes. However, due to the limitations

Microstructure Modification of Additively Manufactured Mo–9Si–8B by Annealing and Its Effects on High‐Temperature Mechanical Properties

open access: yesAdvanced Engineering Materials, EarlyView.
Postbuild annealing systematically modifies the phase fractions and morphology of EB‐PBF processed Mo–9Si–8B. Quantitative microstructure–property correlations reveal how controlled phase evolution enhances high‐temperature compressive strength and creep resistance.

Investigating the Effect of Inclination Angle and the Influence of Scan Parameters on the Appearance and Thermal and Mechanical Properties of Filigree Tension Rods of LPBF‐Manufactured NiTi Shape‐Memory Alloys

open access: yesAdvanced Engineering Materials, EarlyView.
This article investigates the dependence of the properties on the manufacturing orientation in the form of the inclination angle to the build plate of LPBF‐fabricated NiTi rods with a diameter of 150–220 µm. Metallographic, chemical, thermal, and mechanical characterization show behavior under identical manufacturing conditions that ranges from ...

Hydrological factors influencing sediment concentration fluctuations in small drainage basins [PDF]

open access: yes, 1971
Although sediment concentrations measured in two contrasting streams in East Yorkshire fluctuate in response to similar hydrological factors, the effectiveness of these factors reflects the environmental characteristics of the drainage basins ...

Suspended sediment properties and suspended sediment flux estimates in an inundated urban environment during a major flood event [PDF]

open access: yes, 2012
During a major flood event, the inundation of urban environments leads to some complicated flow motion most often associated with significant sediment fluxes.

Effect of Vegetation on Flow and Concentration of Suspended Sediment

open access: yesPROCEEDINGS OF THE JAPANESE CONFERENCE ON HYDRAULICS, 1989
Mathmatical models for defining the lateral distributions of velocity and suspended sediment concentration in channels with vegetation are presented. Singular perturbation technique is used to define the velocity distribution, from which the sediment distribution is derived.

Discrepancies Between Micro Versus Macroscale Viscoelastic Properties in a Microplastic‐Tissue Composite Model

open access: yesAdvanced Engineering Materials, EarlyView.
This study explores the discrepancies between bulk mechanics and spatial mapping in a tissue‐mimetic hydrogel model. Microplastic particles create localized stiff mechanical microenvironments that are detectable by cellular‐scale nanoindentation but leave bulk properties unchanged as measured by rheology.
