The trouble with shear stress
Predicted bedload fluxes often have large errors partly because calculations usually do not
include spatial and temporal flow variability. Sediment motion is driven by a temporal …

Resistance is not futile: Grain resistance controls on observed critical shields stress variations
Estimates of the onset of sediment motion are integral for flood protection and river
management but are often highly inaccurate. The critical shear stress (τ* c) for grain …

Experimental insights into the threshold of motion in alluvial channels: Sediment supply and streambed state
Flume experiments were conducted to understand the role of episodic sediment supply on
the threshold of motion, streambed state, and stability in gravel bed channels. We …

On how episodic sediment supply influences the evolution of channel morphology, bedload transport and channel stability in an experimental step‐pool channel
We present results from flume experiments in which an 8% steep channel with longitudinal
width variations and step‐pool morphology was subjected to sediment feed pulses of …

Response of a small, forested stream to a large input of sediment
C McDowell, MA Hassan - Geomorphology, 2024 - Elsevier
In small headwater channels coupled to hillslopes, episodic supplies of sediment from
events like landslides can dominate local channel morphodynamics and impact ecosystem …

Rough correlations: Meta‐analysis of roughness measures in gravel bed rivers
Bed roughness height (k) is a key parameter for velocity prediction in open‐channel flows.
There is not yet a firm consensus about whether characteristic particle size D84 or (standard …

The influence of coarse particle abundance and spatial distribution on sediment transport and cluster evolution in steep channels under sediment-starved conditions
Large particles strongly influence flow resistance, energy dissipation, bed stability, and
channel morphology in mountain streams. We conducted flume experiments to evaluate …

Co‐evolution of coarse grain structuring and bed roughness in response to episodic sediment supply in an experimental aggrading channel
We use flume experiments to better understand how gravel‐bed channels maintain bed
surface stability in response to pulses of sediment supply. Bed elevations and surface …

Gravel‐bed river evolution in earthquake‐prone regions subject to cycled hydrographs and repeated sediment pulses
Sediment often enters rivers in the form of sediment pulses associated with landslides and
debris flows. This is particularly so in gravel‐bed rivers in earthquake‐prone mountain …
