Field measurements on beach profile and vegetation were conducted in the region from a backshore to the foot of the foredune. The measurements showed that beach grasses influenced the beach profile changes. When the grasses grew, the sediment blown by wind was accumulated in the seaward side of the region. When the grasses were absent, on the other hand, the blown sediment was accumulated in the landward side, near the foot of the foredune.
　A simulation model for aeolian sand transport in the region was developed and compared with the measurements in the field. The comparisons showed that the model qualitatively reproduced cross-shore distributions of the aeolian sand transport rate with and without vegetation.
