The physics of wind-blown sand and dust

JF Kok, EJR Parteli, TI Michaels… - Reports on progress in …, 2012 - iopscience.iop.org
The transport of sand and dust by wind is a potent erosional force, creates sand dunes and
ripples, and loads the atmosphere with suspended dust aerosols. This paper presents an …

The physics of sediment transport initiation, cessation, and entrainment across aeolian and fluvial environments

T Pähtz, AH Clark, M Valyrakis… - Reviews of …, 2020 - Wiley Online Library
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 …

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 …

The physics of aeolian sand transport

A Valance, KR Rasmussen… - Comptes …, 2015 - comptes-rendus.academie-sciences …
A major advance in the study of wind-blown sand started seventy years ago with the seminal
work of Bagnold [1]. Since then and in particular in the last decades, important progress has …

Aeolian creep transport: A review

P Zhang, DJ Sherman, B Li - Aeolian Research, 2021 - Elsevier
This paper reviews the literature on the nature of aeolian creep, the field and wind tunnel
methods used to measure creep transport, the relative contribution of creep transport to total …

Field evidence for the initiation of isolated aeolian sand patches

P Delorme, JM Nield, GFS Wiggs… - Geophysical …, 2023 - Wiley Online Library
Sand patches are one of the precursors to early stage protodunes and occur widely in both
desert and coastal aeolian environments. Here we show field evidence of a mechanism to …

The cessation threshold of nonsuspended sediment transport across aeolian and fluvial environments

T Pähtz, O Durán - Journal of Geophysical Research: Earth …, 2018 - Wiley Online Library
Using particle‐scale simulations of nonsuspended sediment transport for a large range of
Newtonian fluids driving transport, including air and water, we determine the bulk transport …

Aeolian sand transport: Length and height distributions of saltation trajectories

TD Ho, A Valance, P Dupont, AO El Moctar - Aeolian Research, 2014 - Elsevier
We report wind-tunnel measurements on aeolian sand transport aiming at characterizing the
distribution of the length and height of trajectories of the saltating particles. We employ a …

The effect of turbulence on drifting snow sublimation

Z Wang, N Huang, T Pähtz - Geophysical Research Letters, 2019 - Wiley Online Library
Sublimation of drifting snow, which is significant for the balances of mass and energy of the
polar ice sheet, is a complex physical process with intercoupling between ice crystals, wind …

Unified model of sediment transport threshold and rate across weak and intense subaqueous bedload, windblown sand, and windblown snow

T Pähtz, Y Liu, Y Xia, P Hu, Z He… - Journal of Geophysical …, 2021 - Wiley Online Library
Nonsuspended sediment transport (NST) refers to the sediment transport regime in which
the flow turbulence is unable to support the weight of transported grains. It occurs in fluvial …
