Abstract

This study conducted field observations in terms of the number of blown sand impacts and wind velocity at an open ocean beach in Japan, in order to investigate characteristics of Charnock constant and aeolian sand transport flux over a sand dune slope. The number of blown-sand impacts was measured by aeolian sand flux sensor UD-101. As a result of the wind data analysis, the Charnock constant of a roughness length equation had a larger value over the slope compared to over a flat. Furthermore, as a result of the blown sand impact analysis, the aeolian flux over the slope tended to be larger than that over the flat. These fundamental findings in the field will become a great help for further investigation of the aeolian sand transport mechanisms.
