Bed-Load Transport Equation on Arbitrarily Sloping Beds [PDF]
Journal of Hydraulic Engineering, 2008 This work presents a simple tool to evaluate bed-load transport intensity and direction on arbitrarily sloping beds with local longitudinal and transversal inclinations up to 25° and in the case of uniform sediments and low values of the applied Shields stress.

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

Hydraulic Model Prediction of the Total Load of Sediment Transport in The Euphrates River at The Upstream Ramadi Barrage [PDF]
E3S Web of Conferences, 2023 Examining river engineering properties and bed erosion is one of the most challenging but crucial issues in river engineering and sediment hydraulics, so preventing erosion and sedimentation is one of the primary goals of river management and prediction ...

Sedimentation Patterns in Mountainous Reservoirs under the Combined Influence of Suspended Load and Bed Load: A Case Study of Tianzishan Reservoir in Hunan [PDF]
长江科学院院报[Objectives] This study aims to quantify the respective contributions of suspended load and bed load to reservoir sedimentation over different operational periods, and to evaluate the impacts of upstream bed load supply rate, grain size distribution, and

International Journal of Rail transportation, 2021 Ballast bed deformation is significantly influenced by its internal stress state. However, investigations concerning ballast bed deformation focus mainly on the deformation behaviour under various external loading conditions or ballast states, where the ...

Experimental study on non-uniform sediment motion characteristics
Shui kexue jinzhan, 2016 The sand in a natural riverbed is usually non-uniform and is considered as the basis for simulating and forecasting the evolution of the natural riverbed, to accurately understand the movement of non-uniform sediment particles.

A Turbulence‐Based Bed‐Load Transport Model for Bare and Vegetated Channels
Geophysical Research Letters, 2018 Previous studies have shown that sediment transport models based on bed shear stress (τ) are not accurate for regions with vegetation. The present study demonstrated that the inaccuracy arises from the influence of vegetation‐generated turbulence.

Role of eelgrass on bed‐load transport and sediment resuspension under oscillatory flow
Limnology and Oceanography, 2019 Coastal vegetation is widely attributed to stabilize sediment. While most studies focused on how canopy causes flow reduction and thereby affects sediment dynamics, the role of roots and rhizomes on stabilizing the surface sediment has been less well ...
