Dynamics and mechanics of bed-load tracer particles [PDF]
Earth Surface Dynamics, 2014 Understanding the mechanics of bed load at the flood scale is necessary to link hydrology to landscape evolution. Here we report on observations of the transport of coarse sediment tracer particles in a cobble-bedded alluvial river and a step-pool ...

Transport relaxation time and length scales in turbulent suspensions [PDF]
, 2010 We show that in a turbulent flow transporting suspended sediment, the unsaturated sediment flux $q(x,t)$ can be described by a first-order relaxation equation.

A Knowledge‐Based Approach for Understanding and Managing Additive Manufacturing Data
Advanced Engineering Materials, EarlyView.Additive manufacturing processes generate a large amount of data. Effectively managing, understanding, and retrieving information from this data remains a major challenge. Therefore, we propose an ontology‐based approach to integrate heterogeneous data, enable semantic queries, and support decision‐making.

Acta Scientiarum Polonorum. Formatio Circumiectus, 2020 Aim of the study: The aim of the study was to analyse the reasons for the occurrence of intensive suspended load transport in the area of meander 1. The river load transport caused significant morphological changes in the Upper Oder River bed system.

Bed-Load Transport in Circular Pipe with Deposit Bed
PROCEEDINGS OF HYDRAULIC ENGINEERING, 1994 The flow resistance and bed-load discharge in a circular pipe with deposit bed is investigated by numerically analyzing with algebraic stress model of turbulence. The present calculation has clarified shearstress along the boundary including the surface of the deposit bed, which distributes transversely. By applying Swiss-formula for bedload transport,
