Sediment Transport: New Approach and Analysis
TLDR
In this article, the relationship of sediment transport to fluid flow is considered and predictive equations are derived which relate total sediment flux to measurable properties of flow, and a preliminary comparison is made with observations from other sources, including natural rivers.Abstract:
The relationship of sediment transport to fluid flow is considered. Physical reasoning leads to dimensionless groupings of the variables which are different for coarse sediment and for fine sediment, because of dissimilar modes of transport. This concept provides a basis for a new analysis of data from flume experiments, and a method for dealing with transitional sizes of sediment is suggested. The analysis of experimental data supports the theory put forward and predictive equations are derived which relate total sediment flux to measurable properties of flow. A preliminary comparison is made with observations from other sources, including natural rivers.read more

Sediment transport; Part I, Bed load transport
TL;DR: In this article, a method is presented which enables the computation of the bed-load transport as the product of the saltation height, the particle velocity and the bed load concentration.
Journal ArticleDOI
Sediment Transport, Part II: Suspended Load Transport
TL;DR: In this article, a method is presented which enables the computation of the suspended load as the depth-integration of the product of the local concentration and flow velocity, based on the calculation of the reference concentration from the bed-load transport.

Turbulent open-channel flows with variable depth across the channel
Koji Shiono,Donald W. Knight +1 more
TL;DR: In this paper, the lateral distributions of depth-mean velocity and boundary shear stress for straight open channels with prismatic complex cross-sections are derived theoretically for channels of any shape, provided that the boundary geometry can be discretized into linear elements.
