The use of computational models for solving sediment transport and fate problems is
relatively recent compared with the use of physical models. Several considerations govern …

We provide a probabilistic definition of the bed load sediment flux. In treating particle
positions and motions as stochastic quantities, a flux form of the Master equation (a general …

A one‐dimensional numerical model for simulating unsteady flow and sediment transport in
open channels is presented and tested. The flow hydrodynamics is represented by the …

Particles transported as bed load within a specified streambed area possess a distribution of
velocities. This distribution figures prominently in describing the rate of sediment transport …

Particles transported as bed load within a specified streambed area possess at any instant a
distribution of velocities. This distribution figures prominently in describing the rates of …

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 …

Bed-load transport is commonly evaluated in the condition of a hydrostatic pressure
distribution of the flow field; while this condition is reasonable for quasi-steady, quasi …

Bed load transport is a highly complex process. The probability density function (PDF) of
particle velocities results from the local particle momentum variability in response to fluid …

This work is focused on a numerical finite volume scheme for the coupled shallow water-
Exner system in 1D applications with arbitrary geometry. The mathematical expressions …

Reduced‐order models remain essential tools for meander modeling, especially for
processes at large length scales and long time scales, probabilistic simulations, rapid …
