A high‐resolution data set obtained from high‐speed imaging of coarse sand particles
transported as bed load allows us to confidently describe the forms and qualities of the …

In gravel bed rivers, bed load transport exhibits considerable variability in time and space.
Recently, stochastic bed load transport theories have been developed to address the …

In the last decade several efforts were devoted to model sediment‐particle transport in rivers
as a stochastic process. Experimental observations are therefore needed to validate these …

Sediment particles transported as bed load undergo alternating periods of motion and rest,
particularly at weak flow intensity. Bed load transport can be investigated by either following …

ABSTRACT A study of weak bed load over a plane bed is presented with a particular focus
on the motion and diffusion of individual particles that were tracked along their movements …

The ideas of advection and diffusion of sediment particles are probabilistic constructs that
emerge when the Master equation, a precise, probabilistic description of particle …

We describe the most likely forms of the probability distributions of bed load particle
velocities, accelerations, hop distances, and travel times, in a manner that formally appeals …

A series of experiments were conducted in a flume to study bed-load transport. The motion
of bed-load particles was captured by a series of images taken by a high-speed camera. A …

Theoretical and experimental work (Furbish et al., 2021a, b, c) indicates that the travel
distances of rarefied particle motions on rough hillslope surfaces are described by a …

Bedload sediment transport is the basic physical ingredient of river evolution. Formulae exist
for estimating transport rates, but the diffusive contribution to the sediment flux, and the …
