Collisions of quartz grains with a sand bed : the influence of incident angle

Auteurs :

Description :
This study supports a view of moving grain interaction with the bed in which saltation provides the power to mobilize grains but ripple growth is associated with reptation and particularly with a pattern of impact which develops with the bed relief. Creep in more active on upwind facing slopes than at the crest, which therefore is a zone of net creep grain deposition.
