Abstract

On Makuhari Beach located in Tokyo Bay, an artificial beach was built in front of the reclaimed land in 1979, and this beach was widely used for recreation. However, the beach had gradually been eroded. In 2009, a jetty was extended in the middle of the beach, and 12,000 m3 of gravel with the grain size of 4.2 mm was nourished on the beach between the south and the central jetties. Although an artificial beach was produced in parallel with the seawall line, the nourishment gravel was transported northward and was deposited to form a high berm in the northern part. This movement of the nourishment gravel was investigated by field observation.
