The potential rate of bed-load transport [PDF]
Proceedings of the National Academy of Sciences of the United States of America, 2006 Averages of measurements made in three rivers characterized by a high availability of sediment in relation to runoff, and comparable data that represent the high end of the range of transport rates observed during three sets of laboratory experiments, confirm there is an upper, particle-size-dependent limit to bed-load transport ...

A general power equation for predicting bed load transport rates in gravel bed rivers [PDF]
Water Resources Research, 2004 A variety of formulae has been developed to predict bed load transport in gravel bed rivers, ranging from simple regressions to complex multiparameter formulations. The ability to test these formulae across numerous field sites has, until recently, been hampered by a paucity of bed load transport data for gravel bed rivers.

The Effect of Hydraulic Partitioning on Prediction the Rate of Bed Load Transport in Gravel-bed Rivers using Support Vector Machine [PDF]
جغرافیا و پایداری محیط, 2019 Evaluation and prediction of sediment transport and associated processes have been one of the main issues of hydraulic and river engineers. There are some variables which affect the amount of bed load of a stream or river which may carry such as ...

Experimental study on the impact of bed forms on bed load transport in mountain streams
Shuili Shuiyun Gongcheng Xuebao, 2021 The flume experiments of bed load transport in the conditions of highslope shallow water flow were carried out in order to explore the impact of flow hydraulics and bed forms on bed load transport in gravel-cobble rivers in mountainous areas.

A microstructural approach to bed load transport: mean behaviour and fluctuations of particle transport rates [PDF]
Journal of Fluid Mechanics, 2014 AbstractThis paper concerns a model of bed load transport, which describes the advection and dispersion of coarse particles carried by a turbulent water stream. The challenge is to develop a microstructural approach that, on the one hand, yields a parsimonious description of particle transport at the microscopic scale and, on the other hand, leads to ...

Estimating sand bed load in rivers by tracking dunes: a comparison of methods based on bed elevation time series [PDF]
Earth Surface Dynamics, 2020 Quantifying bed-load transport is paramount to the effective management of rivers with sand or gravel-dominated bed material. However, a practical and scalable field methodology for reliably estimating bed load remains elusive.

Impact of Vegetation on Bed Load Transport Rate and Bedform Characteristics [PDF]
Water Resources Research, 2019 AbstractThe impacts of aquatic vegetation on bed load transport rate and bedform characteristics were quantified using flume measurements with model emergent vegetation. First, a model for predicting the turbulent kinetic energy, kt, in vegetated channels from channel average velocity U and vegetation volume fraction ϕ was validated for mobile sediment

Determining the scales of collective entrainment in collision-driven bed load [PDF]
Earth Surface Dynamics, 2018 Fluvial bed-load transport is notoriously unpredictable, especially near the threshold of motion where stochastic fluctuations in sediment flux are large.

A Formula for The Maximum Rate of Bed-load Transport on Smooth and Fixed Bed
PROCEEDINGS OF HYDRAULIC ENGINEERING, 1994 This paper describes a new formula for the calculation of the maximum rate of bed-load transport on smooth and fixed beds. The transport rate in unit width is expressed as the product of the volume of the moving particles on unit area of bed surface and their mean advancing velocity.
