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 ...

Influence of Bed‐Load Transport on Flow Resistance of Step‐Pool Channels
Water Resources Research, 2018 This study investigates the influence of bed‐load transport on flow resistance and bed stability in steep step‐pool channels. A total of 86 flume experiments was performed.

Quantification of bed-load transport over dunes [PDF]
E3S Web of Conferences, 2018 There is disagreement in the literature as to whether a shear stress-based approach can be used to accurately predict sediment transport over dunes. This study aims to address this disagreement.

The impact of intermittency on bed load sediment transport [PDF]
Geophysical Research Letters, 2021 AbstractSediment transport by wind or water near the threshold of grain motion is dominated by rare transport events. This intermittency makes it difficult to calibrate sediment transport laws, or to define an unambiguous threshold for grain entrainment, both of which are crucial for predicting sediment transport rates. We present a model that captures

Development of a machine learning model for river bed load [PDF]
Earth Surface Dynamics, 2023 Prediction of bed load sediment transport rates in rivers is a notoriously difficult problem due to inherent variability in river hydraulics and channel morphology.

Hysteretic Implications for Graded Bed Load Sediment Transport in Symmetrical Hydrograph Flows
Frontiers in Environmental Science, 2021 Differential parametric values associated with bed load sediment transport, that result at the same discharge levels on the rising and falling limbs of a flood hydrograph, are usually defined as bed load hysteresis.

Quantitative Study on Bed Load Proppant Transport during Slickwater Hydraulic Fracturing
Lithosphere, 2021 Bed load proppant transport is a significant phenomenon during slickwater hydraulic fracturing. However, the mechanism of bed load proppant transport is still unclear.

A bed load transport equation based on the spatial distribution of shear stress – Oak Creek revisit [PDF]
Earth Surface Dynamics, 2020 Bed load transport formulations for gravel-bed rivers are often based on reach-averaged shear stress values. However, the complexity of the flow field in these systems results in wide distributions of shear stress, whose effects on bed load transport are

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.

Bed load transport by submerged jets [PDF]
Proceedings of the National Academy of Sciences, 1979 Some similarities are presented between the bed load transport of noncohesive grains in long rivers and at a local, jet-induced scour. Experiments are described in which a submerged two-dimensional slot nozzle, inclined downward, eroded a deep sand bed.
