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 ...

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 ...

Bed-load transport in steep channels

1991
In this paper, hydraulic resistance, critical tractive force and bed-load discharge in steep gravel-bed channels are investigated. If the velocity distribution, which is much affected by small relative submergence, is formulated, the resistance law, dimensionless critical tractive force and bed-load formula can be reasonably predicted, and they are ...

Bed-Load Transport Equation for Sheet Flow

Journal of Hydraulic Engineering, 2003
When open-channel flows become sufficiently powerful, the mode of bed-load transport changes from saltation to sheet flow. Where there is no suspended sediment, sheet flow consists of a layer of colliding grains whose basal concentration approaches that of the stationary bed. These collisions give rise to a dispersive stress that acts normal to the bed
