Development of the saltation system under controlled environmental conditions

Auteur :
ARNOLD, S.

Description :
Results are presented from wind-tunnel experiments that were designed to address the simultaneous spatial and temporal development of the saltation system, with and without artificial sand feed. The development of the saltation system was monitored over a streamwise length of 8 m during a period of 3600 s. Mass flux data were measured simultaneously at 1 m intervals by the downwind deployment of seven Aarhus sand traps. Wind velocity data were collected throughout the experiments. Through time the saltation system develops from a transport-limited to a supply-limited system.
