several snowmelt seasons. Cumulative displacements were measured using passive …

Geomorphic controls on tracer particle dispersion in gravel‐bed rivers

MA Hassan, DN Bradley - Gravel‐bed rivers: Processes and …, 2017 - Wiley Online Library
In this chapter, we present a review of sediment tracing studies in gravel bed streams. Our
primary objective is to critically assess the use of tracers for obtaining information on …

A statistical description of particle motion and rest regimes in open‐channel flows under low bedload transport

MX Liu, A Pelosi, M Guala - Journal of Geophysical Research …, 2019 - Wiley Online Library
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 …

Dynamics and mechanics of bed-load tracer particles

CB Phillips, DJ Jerolmack - Earth Surface Dynamics, 2014 - esurf.copernicus.org
Understanding the mechanics of bed load at the flood scale is necessary to link hydrology to
landscape evolution. Here we report on observations of the transport of coarse sediment …

Direct observation of heavy‐tailed storage times of bed load tracer particles causing anomalous superdiffusion

DN Bradley - Geophysical Research Letters, 2017 - Wiley Online Library
A consensus has formed that the step length distribution of fluvial bed load is thin tailed and
that the observed anomalous superdiffusion of bed load tracer particles must arise from …

Exploring a semimechanistic episodic Langevin model for bed load transport: Emergence of normal and anomalous advection and diffusion regimes

N Fan, A Singh, M Guala… - Water Resources …, 2016 - Wiley Online Library
Bed load transport is a highly stochastic, multiscale process, where particle advection and
diffusion regimes are governed by the dynamics of each sediment grain during its motion …

The elements and richness of particle diffusion during sediment transport at small timescales

DJ Furbish, SL Fathel, MW Schmeeckle… - Earth Surface …, 2017 - Wiley Online Library
