Journal ArticleDOI
Fractional dispersion in a sand bed river
TL;DR: In this article, the authors revisited a nearly 50 year old tracer experiment in which the tracer plume exhibits the hallmarks of dispersive transport described by a step length distribution with a divergent second moment and no characteristic dispersive size.
Journal ArticleDOI
Measuring gravel transport and dispersion in a mountain river using passive radio tracers
TL;DR: This paper used passive integrated transponder (PIT) tags to label 893 coarse gravel clasts and placed them in Halfmoon Creek, a small alpine stream near Leadville, Colorado, USA.
Journal ArticleDOI
Trouble with diffusion: Reassessing hillslope erosion laws with a particle-based model
TL;DR: In this paper, a simple particle-based model of sediment transport on a hillslope is used to study the relationship between grain motion statistics and macroscopic landform evolution, where surface grains are dislodged by random disturbance events with probabilities and distances that depend on local microtopography.
Journal ArticleDOI
The storage time, age, and erosion hazard of laterally accreted sediment on the floodplain of a simulated meandering river
TL;DR: In this article, the authors investigate the relationship between sediment age and erosion, and find that the erosion hazard decreases with sediment age, leading to a storage time distribution that is not exponential.
Journal ArticleDOI
Evolution of tributary junctions and their capacity for rearing juvenile Chinook salmon (Oncorhynchus tshawytscha) on a regulated river
Todd H. Buxton,D. Nathan Bradley +1 more
TL;DR: In this paper , the authors examine the subsequent evolution of the Trinity River's alluvial channel through 60 years of increases in regulated mainstem flow regimes in an unconfined and confined valley where Rush and Indian creeks respectively join the river 6.9 and 26.7 river kilometres from Lewiston Dam.
