Predicting the morphodynamics of sedimentary landscapes due to fluvial and aeolian flows
requires answering the following questions: Is the flow strong enough to initiate sediment …

An erodible bed sheared by a fluid flow, gas or liquid, is generally unstable, and bed forms
grow. This review discusses the following issues, in light of the recent literature: What are the …

Rivers are important agents of change that shape the Earth's surface and evolve through
time in response to fluctuations in climate and other environmental conditions. They are …

This paper outlines the various approaches used to calculate bedload transport. As bedload
transport exhibits considerable spatial and temporal variations, computing the bedload …

Understanding the statistics of bedload particle motions is of great importance. To model the
hop events which are defined as trajectories of particles moving successively from the start …

The geometry of alluvial river channels both controls and adjusts to the flow of water and
sediment within them. This feedback between flow and form modulates flood risk, and the …

A model of sand transport in water is produced by combining a turbulence‐resolving large
eddy simulation (LES) with a discrete element model (DEM) prescribing the motion of …

Vegetation is ubiquitous in river channels and floodplains and alters mean flow conditions
and turbulence. However, the effects of vegetation patches on near‐bed turbulence, bed …

Wind-driven sand transport generates atmospheric dust, forms dunes, and sculpts
landscapes. However, it remains unclear how the flux of particles in aeolian saltation—the …

Earth's surface is composed of a staggering diversity of particulate–fluid mixtures: dry to wet,
dilute to dense, colloidal to granular and attractive to repulsive particles. This material variety …
