Bed load transport fluctuations in a gravel bed laboratory channel
Water Resources Research, 1988Flume experiments were conducted to investigate the mechanisms of transport of a gravel‐sand mixture by shallow unidirectional flows. Two water recirculating sediment feed flumes were used: one with a 6 m long and 0.15 m wide channel and other with an 11 m long channel with widths of 0.74 m and 0.53 m.

Simulating Bed-Load Transport in a Complex Gravel-Bed River
Journal of Hydraulic Engineering, 2007An existing two-dimensional mobile-bed hydrodynamic model has been modified to simulate bed-load transport in a complex gravel-bed river. We investigated the sensitivity of predicted bed load to control parameters, and compared model predictions of flow depth, shear stress, and gravel transport with field measurements made from the river.

Bed Load Transport in a River Meander
Water Resources Research, 1984Bed load transport in Muddy Creek, Wyoming, a sand‐bedded meandering river with equilibrium bottom topography, was found to consist of a zone of maximum sediment flux that shifted across the channel from near the inside bank in the upstream part of the bend toward the pool at the minimum radius of curvature.

Bed-load transport in steep channels
1991In 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, 2003When 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
