... accompanies the occurrence of root traces. Interpretation . The overall normally graded nature of the LF indicates a waning flow. The superposition of the increasing angle of climb points to an increasing rate of suspension fallout relative to bedload migration ( Allen 1982 ; Chaudhuri 2005 ; García...

... field disproves the liquefaction theory, but HAD morphology may arise due to local bedload-dominated conditions within the field. Best et al. appeal to Cisneros et al. (2020) to support their arguments. We attempted to explore how well the algorithm used by Cisneros et al. characterized dune morphology...

... displays characteristics of confined–uncontained turbidites: grain-size breaks and coarse bedload indicative of ubiquitous flow bypass; short-range grain-size fractionation across flow; stacked sandy bed-sets in the flow axes. We reconstruct sand fairways for over 300 km across the region and propose...

...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...

... ) or debris flows ( Cannon et al., 2001 ). Both bedload ( Beaty, 1994 ) and suspended sediment concentrations ( Malmon et al., 2007 ; Ryan et al., 2011 ) typically increase by several orders of magnitude after burns. Although sediment concentrations often return toward pre-fire levels within several years...

... close to the dam, which promotes transport of coarse-grained sediment as bedload ( Fig. 12 ). The condition of low flow discharge and associated backwater profiles persists for much of the year, generating the overall downstream fining of river-bed sediment observed in the model simulations, while...

... 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 is a multiple of viscous sublayer thickness, it is unclear why such a criterion would control...
