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

TL;DR: In this paper, the authors use weakly nonlinear and dynamical systems theory complemented by numerical simulation to predict the patterns that will form from disturbances of infinitesimal amplitude.

sedFlow – a tool for simulating fractional bedload transport and longitudinal profile evolution in mountain streams

TL;DR: SedFlow as discussed by the authors is a one-dimensional model that aims to realistically reproduce the total transport volumes and overall morphodynamic changes resulting from sediment transport events such as major floods and is intended for temporal scales from the individual event (several hours to few days) up to longer-term evolution of stream channels.

Application of evolutionary computation to open channel flow modelling
TL;DR: In this paper, a semi-automated framework for the Shiono Knight Method (SKM) was proposed to evaluate the ability of an evolutionary algorithm to provide insight and guidance into the correct magnitude and trend of the three parameters required in order to successfully apply a quasi 2D depth averaged Reynolds Averaged Navier Stokes (RANS) model to the flow in prismatic open channels.

A spectral approach for the stability analysis of turbulent open-channel flows over granular beds
TL;DR: In this paper, a novel Orr-Sommerfeld-like equation for gravity-driven turbulent open-channel flows over a granular erodible bed is derived, and the linear stability analysis is developed.

An explicit two-dimensional finite element model to simulate short- and long-term bed evolution in alluvial rivers
Abstract: This paper presents a two-dimensional model to solve the vertically averaged shallow water and sediment transport equations for short- and long-term simulations. The model implements a four-time-step explicit scheme that permits longer time steps than previous explicit finite element models. Also, an algorithm is incorporated that decreases considerably computer times for long-term simulations while preserving the advantages of explicit schemes. The model results compare very well with analytical solutions for simplified one- and two-dimensional problems. A 5-year simulation for the Apure River in Venezuela, demonstrate the ability of the model to predict long-term evolution for large rivers in a computational efficient manner. The resulting bed evolution patterns compare well to the observed behavior of control structures used in similar applications.
