Aeolian dust ripples : their occurrence, morphometrical characteristics, dynamics and origin

Auteur :
GOOSSENS, D.

Description :
In this paper, the main morphometric and dynamic properties of aeolian ripples formed in a wind tunnel during the deposition of natural, silt-sized dust particles over a flat horizontal surface are investigated. Two different (but counteracting) processes play a role in dust ripple dynamics : an aerodynamic process and an impact process, of which the first causes an upwind and the second a downwind migration of the ripples.
