Sediment Transport, Part II: Suspended Load Transport
TLDR
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.Abstract:
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. The method is based on the computation of the reference concentration from the bed-load transport. Measured concentration profiles have been used for calibration. New relationships are proposed to represent the size gradation of the bed material and the damping of the turbulence by the sediment particles. A verification analysis using about 800 data shows that about 76% of the predicted values are within 0.5 and 2 times the measured values.read more

Development and validation of a three-dimensional morphological model
TL;DR: The DELFT3D-FLOW module as discussed by the authors is a 3D flow solver for modeling sediment transport patterns in the water column of the DELFT-3D flow model, which is used to model both suspended and bedload transport of noncohesive sediment.

From Oil-Prone Source Rock to Gas-Producing Shale Reservoir - Geologic and Petrophysical Characterization of Unconventional Shale Gas Reservoirs
TL;DR: In this paper, total organic carbon (TOC), maturity level (vitrinite reflectance), mineralogy, thickness, and organic matter type are used to classify organic matter that ranges from oil-prone algal and herbaceous to gas-prone woody/coaly material.

Sediment Transport, Part III: Bed Forms and Alluvial Roughness
TL;DR: In this paper, a verification analysis using about 1,500 (alternative) reliable flume and field data shows good results in predicting the hydraulic roughness (friction factor).

Unified view of sediment transport by currents and waves. I: Initiation of motion, bed roughness, and bed-load transport
TL;DR: In this paper, the effect of fine silt on the bed composition and on initiation of motion (critical conditions) of sediment beds over the full range of conditions (silts to gravel) is discussed.

Experiments on a Gravity-Free Dispersion of Large Solid Spheres in a Newtonian Fluid under Shear
TL;DR: In this article, a large number of spherical grains of diameter D = 0.13 cm were sheared in Newtonian fluids of varying viscosity (water and a glycerine-water-alcohol mixture) in the annular space between two concentric drums.

A monograph on sediment transport in alluvial streams
TL;DR: In this article, the authors proposed the principle of similarity for the prediction of stage-discharge relations in alluvial streams. But they did not consider the effect of the number of particles in the stream.

Sediment Transport: New Approach and Analysis
TL;DR: 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.

A Sediment Transport Model for Straight Alluvial Channels
Frank Engelund,Jørgen Fredsøe +1 more
TL;DR: In this paper, a simple mathematical model for sediment transport in straight alluvial channels is presented, which is based on physical ideas related to those introduced by Bagnold (1954), was originally developed in two steps, the first describing the bed load transport and the second accounting for the suspended load.
