TLDR
In this article, an attempt is made to derive an empirical law of bed-load transport based on recent experimental data and the results and interpretation of tests already made known in former publications of the Laboratory for Hydraulic Research and Soil Mechanics at the Federal Institute of Technology, Zurich.Abstract:
In the following paper, a brief summary is first of all given of the results and interpretation of tests already made known in former publications of the Laboratory for Hydraulic Research and Soil Mechanics at the Federal Institute of Technology, Zurich. After that, an attempt is made to derive an empirical law of bed-load transport based on recent experimental data. We desire to state expressly that by bed-load transport is meant the movement of the solid material rolling or jumping along the bed of a river; transport of matter in suspension is not included.read more

Channel flow competence and sediment transport in upland streams in southeast Australia
Christopher Thompson,Jacky Croke +1 more
TL;DR: In this paper, the authors used a locally parametrized entrainment equation to determine grain size transport thresholds for selected upland streams in southeast Australia, and applied it to a regime model and applied to mountain streams to investigate whether empirical data improve the delineation of reach types on the basis of dimensionless discharge per unit width (q*) and dimensionless bedload transport (q*b).

Conceptual model for complex river responses using an expanded Lane's relation
David Dust,Ellen Wohl +1 more
TL;DR: In this paper, the width-to-depth ratio (W/d) was introduced as a cross-sectional geometry term and the slope term was defined as the total change in elevation along a channel and inversely proportional to sinuosity and bedform amplitude.

Mesh-free SPH modeling of sediment scouring and flushing
TL;DR: A two-phase mesh-free Lagrangian model, based on the Smoothed Particle Hydrodynamics (SPH) method, is developed and evaluated for the continuum-based study of sediment-water system (a dense submerged granular flow system).

The variation of water-surface slope and its significance for bedload transport during floods in gravel-bed streams
TL;DR: In this article, water-surface slope is treated as a variable in applying a bedload equation, and it is shown that flood bedload yields are about 8 percent higher than those derived with the same equation but with water surface slope held constant and approximating the slope of the channel bed.

More on the Evolution of Bed Material Waves in Alluvial Rivers
TL;DR: In this paper, it has been suggested that the dominance of dispersion appears only because the hyperbolic nature of the governing equations has not been adequately considered; and that the sediment transport equation used in the analyses does not lead to generalizable results.
