Sand ripples and dunes

F Charru, B Andreotti, P Claudin - Annual Review of Fluid …, 2013 - annualreviews.org
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 …

[图书][B] River dynamics: geomorphology to support management

BL Rhoads - 2020 - books.google.com
Rivers are important agents of change that shape the Earth's surface and evolve through

Bedload transport: a walk between randomness and determinism. Part 1. The state of the art

C Ancey - Journal of Hydraulic Research, 2020 - Taylor & Francis
This paper outlines the various approaches used to calculate bedload transport. As bedload
transport exhibits considerable spatial and temporal variations, computing the bedload …

Theoretical analysis for bedload particle deposition and hop statistics

Z Wu, W Jiang, L Zeng, X Fu - Journal of Fluid Mechanics, 2023 - cambridge.org
Understanding the statistics of bedload particle motions is of great importance. To model the

Threshold constraints on the size, shape and stability of alluvial rivers

CB Phillips, CC Masteller, LJ Slater… - Nature Reviews Earth & …, 2022 - nature.com
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 …

Numerical simulation of turbulence and sediment transport of medium sand

MW Schmeeckle - Journal of Geophysical Research: Earth …, 2014 - Wiley Online Library
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 …

The influence of vegetation on turbulence and bed load transport

EM Yager, MW Schmeeckle - Journal of Geophysical Research …, 2013 - Wiley Online Library
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-invariant saltation heights imply linear scaling of aeolian saltation flux with shear stress

RL Martin, JF Kok - Science advances, 2017 - science.org
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 …

Viewing Earth's surface as a soft-matter landscape

DJ Jerolmack, KE Daniels - Nature Reviews Physics, 2019 - nature.com
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 …
