    In this study, the applicability of Rouse's suspended sediment concentration profile for fluvial transport to aeolian transport was shown and a universal system of suspended sand transport in water and air was investigated, in order to obtain knowledge of suspended sand transport in air. Comparison between Rouse's vertical concentration profile and the profile obtained from wind tunnel experimental results indicated that Rouse's profile underestimated the experimental results when the mode of sand particle motion was classified into saltation; however, it agreed with the experimental results when the mode of sand particle motion was classified into suspension under strong wind conditions. The mode of sand particle motion was universally classified on the basis of a dimensionless Rouse number for both fluvial and aeolian transports. Results of this study suggested that Rouse's profile for fluvial transport is possibly applicable to aeolian transport when the Rouse number is roughly greater than 1 under strong wind conditions.
