The saturation length of aeolian sand transport (Ls), characterizing the distance needed by wind‐blown sand to adapt to changes in the wind shear, is essential for accurate modeling of the morphodynamics of Earth's sandy landscapes and for explaining the formation and shape of sand dunes. In the last decade, it has become a widely accepted hypothesis that Ls is proportional to the characteristic distance needed by transported particles to reach the wind speed (the “drag length”). Here we… 

Improved analytical model for the relaxation process of aeolian sand transport

An improved analytical model is proposed, which incorporates the phenomena of "overshoot" and "equilibrium" and the concept of the region of initiation by fluid, and is able to unify the cases with and without upwind sand flux.

The Cessation Threshold of Nonsuspended Sediment Transport Across Aeolian and Fluvial Environments

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 cessation

Aeolian Sand Transport in Out‐of‐Equilibrium Regimes

We investigate the relaxation process toward the equilibrium regime of saltation transport in the context of nonuniform conditions. Relaxation phenomena can be described in terms of a characteristic

Unification of Aeolian and Fluvial Sediment Transport Rate from Granular Physics.

Using transport simulations for a wide range of driving conditions, it is shown that the scaling depends on the manner in which the kinetic fluctuation energy of transported particles is dissipated, and a scaling law is derived (asymptotically Q∼τ^{2}) in simultaneous agreement with measurements in water and air streams.

Cohesion‐Induced Enhancement of Aeolian Saltation

The wind‐driven saltation of granular material plays a key role in various geophysical processes on Earth, Mars, Venus, and Titan. Although interparticle cohesion is known to limit the number of

Numerical simulation of sand transfer in wind storm using the Eulerian-Lagrangian two-phase flow model

A two-dimensional gas-solid flow model is used to investigate the sand particles carrying velocity of the Iran eastern desert area around the railway track as a case study and the results can be used for estimating the sand mitigation of a special desert and land desertification control around railway tracks.

Aeolian Creep Transport: Theory and Experiment

Aeolian sand transport drives geophysical phenomena, such as bedform evolution and desertification. Creep plays a crucial, yet poorly understood, role in this process. We present a model for aeolian

Relaxation processes in Aeolian transport

We investigate experimentally the relaxation process toward the equilibrium regime of saltation transport in the context of spatial inhomogeneous conditions. The relaxation length associated to this



Minimal model for aeolian sand dunes.

We present a minimal model for the formation and migration of aeolian sand dunes in unidirectional winds. It combines a perturbative description of the turbulent wind velocity field above the dune

Measurements of the aeolian sand transport saturation length

The apparent roughness of a sand surface blown by wind from an analytical model of saltation

We present an analytical model of aeolian sand transport. The model quantifies the momentum transfer from the wind to the transported sand by providing expressions for the thickness of the saltation

Continuum saltation model for sand dunes.

It is pointed out that saturation transients are indispensable for a proper description of sand flux over structured terrain, by applying the model to the windward side of an isolated dune, thereby resolving recently reported discrepancies between field measurements and theoretical predictions.

Aeolian transport of sand

A new relation for fluxes close to the threshold velocity ut, namely, qs=a(u*-ut)α with α≈2 with a novel dynamical scaling relation is proposed and explained.

Direct numerical simulations of aeolian sand ripples

Direct numerical simulations of grains interacting with a wind flow are reported, for the first time to the authors' knowledge, able to reproduce the spontaneous growth of ripples with an initial wavelength and a propagation velocity linearly increasing with the wind speed.

The fluctuation property of blown sand particles and the wind-sand flow evolution studied by numerical method

The results indicate that the saturation time decreases with the inlet friction velocity, and it gradually reaches the shortest saturation time of about 1s; the saturation length, which is about 14 m at the usual wind velocity, first increases with wind velocity and then reaches a plateau; within the saturationlength, the sand transport rate at different positions varies with time.

A two-species continuum model for aeolian sand transport

Starting from the physics on the grain scale, we develop a simple continuum description of aeolian sand transport. Beyond popular mean-field models, but without sacrificing their computational
