Modelling Regime Changes of Dunes to Upper-Stage Plane Bed in Flumes and in Rivers
Applied Sciences, 2021 In this paper we derive a new morphological model, with an extended version of the sediment transport model for the mean step length (the average distance travelled by sediment particles), in which this mean step length depends on the mean bed shear ...

Advanced Engineering Materials, EarlyView.Building machine‐readable vocabularies for materials science is slow, expert‐driven work. This study benchmarks 13 large language models on two of its first steps: finding candidate terms in engineering articles and deciding where they belong in a class hierarchy.

Research on bed-load transport formula in the Cheng-Han Reach of the middle Yangtze River
Shui kexue jinzhan, 2017 After the impoundment of Three Gorges Reservoir, the sediment transport in the reach from Chenglingji to Wuhan of the middle Yangtze River is dominated by the bed load which plays important roles in bed morphological changes, and correspondingly the ...

Predicting fractional bed load transport rates: Application of the Wilcock‐Crowe equations to a regulated gravel bed river [PDF]
Water Resources Research, 2009 Bed load samples from four locations in the Trinity River of northern California are analyzed to evaluate the performance of the Wilcock‐Crowe bed load transport equations for predicting fractional bed load transport rates. Bed surface particles become smaller and the fraction of sand on the bed increases with distance downstream from Lewiston Dam. The

Creep Properties and Deformation Mechanism of Additively Manufactured NiAl‐CrMo Composites
Advanced Engineering Materials, EarlyView.Additively manufactured NiAl‐CrMo composites contain numerous interfaces and cell boundaries that control their creep response. At 700°C under high applied stress, creep is dominated by dislocation‐controlled power‐law mechanisms. At 800°C–900°C and lower stresses, creep is primarily diffusion‐controlled along cell boundaries.

Quantification of bed-load transport over dunes
E3S Web of Conferences, 2018 There is disagreement in the literature as to whether a shear stress-based approach can be used to accurately predict sediment transport over dunes. This study aims to address this disagreement.

A flume experiment on critical flow conditions with gravel dunes
Shui kexue jinzhan, 2013 Gravel dunes are the typical form of bed load motion and one of the research focuses in river dynamics,which determines the bed resistance,the bed geometry and the bed load transport rate in alluvial rivers.Most previous studies focused on the fine ...

Modular Critical Element Recycling Platform Using a Nanoporous Additively Manufactured Gyroid
Advanced Engineering Materials, EarlyView.A modular recycling platform integrates 3D‐printed nanoporous gyroid structures to enable efficient critical element recovery. This system utilizes a hierarchical architecture, combining macroscopic channels with polymerization‐induced nanoscale porosity. By systematically tuning structural wall thickness and resin formulation, the platform achieves an
