...Rebecca A. Hodge; Hal Voepel; Julian Leyland; David A. Sear; Sharif Ahmed Abstract The critical shear stress (τ c ) for grain entrainment is a poorly constrained control on bedload transport rates in rivers. Direct calculations of τ c have been hindered by the inability to measure the geometry...

... pore pressures that occur during the failure of thick, loosely packed deposits can produce liquefied avalanches that flow and stop on gentle gradients. As lee-side angles decrease over LADs, downslope currents increase in strength, accelerating avalanches, transporting bedload, and creating smaller...

Both bedload ( Beaty, 1994 ) and suspended sediment concentrations ( Malmon et al., 2007 ; Ryan et al., 2011 ) typically increase by several orders of magnitude after...

... that are not consistent with the observed sloping ripple-dune boundary. Another hypothesis is that ripples predominantly form under bedload transport (e.g., Richards, 1980 ); however, the suspension threshold of Niño et al. (2003) also differs from a constant χ (Fig. DR1). While a constant χ implies that L sat...

... cross-bedding, which suggest a shallow, perennial, sand-bed braided fluvial style with bedload transportation in roughly 1 to 2.5 m deep and relatively wide channels. This fluvial style was possibly influenced by the global absence of substrate stabilizing terrestrial flora in pre-Devonian rivers. Based...

... (2007) showed how the same parameter influences branching and avulsion in depositional rivers. The process of sediment storage and release in bar complexes originally described by Ashmore (1991), leading to large bedload pulses, is closely akin to the storage-and-release process associated with slope...

...) used governing dimensionless parameters (e.g., shear stress) derived from flow measurements in the lower portion of the flow (below the velocity maximum) to highlight similarities between gravity flows and open channels in regard to bedload transport and bed friction. However, this work ( Sequeiros et...
