Estimators of alluvial bed load transport

Earth Surface Processes, 1977
The equilibrium stream represents a compromise between three tendencies: (i) to maximize grain size, (ii) to maximize quantity of bed load transported, and (iii) to minimize bed shear stress (which represents, among other things, water discharge).

Erosion And Transport Of Bed-Load Sediment

Journal of Hydraulic Research, 1976
In this thesis first a general derivation is given of the 'macro'-equations of mass- and linear-momentum balance that govern the mo'mentum transfer from a Newtonian fluid to rigid particles in a fluid-solid mixture. In particular, attention is paid to a) the attenuation of viscous-momentum transfer from the boundary to the interior of a granular bed ...

Bed Load Transport of Sediment Mixtures

Journal of Hydraulic Engineering, 1986
Experiments were conducted on alluvial beds of four sediment mixtures having different arithmetic mean diameters and standard deviations. The bed load transport rates of individual fractions were measured. Einstein's method, Proffitt and Sutherland's method, and Misri's method of calculation of the bed load transport of individual fractions for ...

BED LOAD TRANSPORT IN THE PRESENCE OF WASH LOAD TRANSPORT

ISH Journal of Hydraulic Engineering, 2007
ABSTRACT Experiments were conducted in a 30 m long 0.204 m wide and 0.5 m deep tilting flume to study the effect of different equilibrium concentration of wash load transport on the transport of uniform and nonuniform sediments through an alluvial channel and on the composition of active bed layer.

Bed load transport by natural rivers

Water Resources Research, 1977
Since stream power ω and sediment transport rate i are different values of the same physical quantity, namely, the time rate of energy supply and dissipation, it is rational to relate one to the other. The experimental relation has been difficult to interpret because of the spurious curvature of log‐log plots in which a constant threshold stream power ...

Wave-induced Bed Load Transport

1984
A theory is developed for the velocity and concentration distribution within a moving layer of sediment in oscillatory flow. The bed is assumed flat and consequently all of the sediment moves as bed load. Tests have been carried out in an oscillatory-flow water tunnel.

ERROR INTRODUCED IN MEASUREMENTS OF BED LOAD TRANSPORT

Advances in Hydraulics and Water Engineering, 2002
High accuracy in calculating the transport rate of bed load in natural channels is required for design purposes. This can be achieved through good sampling and reliable data sets. However, measurements of bed load transport can be a difficult task for rivers with flow depths exceeding one meter owing to the methods of measurements that uses either a ...
