Effect of incoming sediment on the transport rate of bed load in mountain streams

International Journal of Sediment Research, 2009
Field experiments were conducted on bed load transport in the Diaoga River, a mountain stream in southwest China, to study the variation of bed load transport with varying sediment supply. The rate of bed load transport is greatly affected by incoming sediment (load and size). Under the same flow conditions, bed load transport rates may differ by three

Bed Load Grain Velocities and Sediment Transport Rates

Water Resources Research, 1984
Theoretical consideration of the dynamics of bed load sediment transport leads to expressions for bed grain velocity and sediment transport rate as, respectively, Ub = a(U* − U*c) and ib = (a/tan α) (U* − U*c) (т0−тc), agreeing in form with many previous analyses.

On the prediction of bed‐load sand transport rate in air

Sedimentology, 1994
ABSTRACTThis paper discusses the parameterization of aeolian mass transport rate beginning with a critical discussion of four different forms of the prediction equation. Following this, recent progress in understanding the physics of the aeolian system is used to suggest an alternative approach which provides some new insights into the prediction of ...

Bed load transport rates during scouring and armoring processes

Journal of Mountain Science, 2010
Dambreak-induced bed scouring may undermine the foundation of bridge piers and other structures, and that destruction can pose a serious threat. Consequently, this paper aims at exploring the mechanisms of scouring and armoring. Firstly, the incipient velocity for nonuniform sediment particles was studied, and a formula was derived based on the angle ...

Formulation of bed shear stress for computing bed-load transport rate in vegetated flows

Physics of Fluids, 2021
Difficulties are often encountered in estimating the bed shear stress in vegetated flows over a sediment bed due to complex interactions of the flow, sediment, and vegetation. Without involving any empirical partition of the bed friction and vegetation resistance, this study presents an analytical approach to evaluate the bed shear stress in the ...
