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

Shear stress and sediment transport calculations for swash zone modelling
TL;DR: In this paper, it was shown that the observed difference in sediment transporting efficiency by the swash uprush compared with the downrush could be mainly due to greater bed shear stress for a given velocity in the more abruptly accelerated uprush.

Theoretical development on the effects of changing flow hydraulics on incipient bed load motion
TL;DR: In this paper, the authors used a velocity profile including a roughness layer, which is a zone of almost constant velocity close to the bed, whose properties (mean velocity and turbulence) depended on the flow's relative depth.

Contrasting the Goals, Strategies, and Predictions Associated with Simplified Numerical Models and Detailed Simulations
TL;DR: Numerical models in geomorphology and geophysics can be arranged along a continuum with 'simulation models' at one end and highly simplified, 'exploratory model' at the other, with quantitative accuracy not as important as simplifying the formalism.

Bed Load Grain Velocities and Sediment Transport Rates
J. S. Bridge,David F. Dominic +1 more
TL;DR: In this article, the authors consider the dynamics of bed load sediment transport and derive expressions for grain velocities and sediment transport rate, respectively, Ub = a(U * − U*c) and ib = (a/tan α) (U* − U *c) (т0−тc), agreeing in form with many previous analyses.

Causes of Concavity in Longitudinal Profiles of Rivers
Sanjiv K. Sinha,Gary Parker +1 more
TL;DR: In this article, a generalized, unified set of models for the longitudinal profile of rivers is presented, and various independent effects that drive concavity in longitudinal rivers are considered and classified, including abrasion of bed particles, aggradation of the river profile, balancing subsidence at a constant speed, and the effect of tributaries adding sediment and water to the main stem of a river.
