This paper reports on a wind tunnel study of the effects of bed slope and wind speed on aeolian mass transport. The use of a sloping wind tunnel has enabled estimation of the friction angle ฮฑ to be about 40ยฐ for saltating particles in the range 170โ540โฮผm. A formula relating dimensionless mass trans
The velocities with which grains were observed to emerge from a sand bed after an intersaltation collision at u\* = 40 cm s-are reported for four bed attitudes, from horizontal bed to adverse bed slope 15". The principal effect of bed angle is to alter the magnitude and direction of the ricochet vel
