Scaling Laws in Aeolian Sand Transport

Physical Review Letters, 2011
We report on wind tunnel measurements on saltating particles in a turbulent boundary layer and provide evidence that over an erodible bed the particle velocity in the saltation layer and the saltation length are almost invariant with the wind strength, whereas over a nonerodible bed these quantities vary significantly with the air friction speed.

Mechanics of Aeolian Sand Transport

1990
This chapter discusses the forces responsible for the initiation of sand movement by wind, including the concepts of fluid threshold and impact threshold, different aeolian transport modes (creep, saltation and suspension), various environmental factors which influence the rate of transport, and processes involved in windblown sand deposition.

Aeolian sand ripples around plants

Physical Review E, 2003
Plants in the desert may locally change the aeolian process, and hence the pattern of sand ripples traveling nearby. The effect of plants on ripples is investigated using a coupled map lattice model with nonuniform coupling coefficients.

Aeolian sand transport and aeolian deposits on Venus: A review

Aeolian Research, 2017
Abstract We review the current state of knowledge about aeolian sand transport and aeolian bedforms on planet Venus. This knowledge is limited by lack of observational data. Among the four planetary bodies of the Solar System with sufficient atmospheres in contact with solid surfaces, Venus has the densest atmosphere; the conditions there are ...
