Abstract
Beach changes after the gravel nourishment were investigated on the Jinkoji and Akashi coasts in Ibaraki Prefecture. The formation of sand layer on the gravel bed due to shoreward sand transport of medium-size and fine sand under the calm wave conditions was observed and three-dimensional beach changes in response to the change in wave direction were also measured between artificial headland Nos. 6 and 7. Even though the sand layer on the gravel layer disappeared due to offshore sand movement under the storm wave conditions, the gravel layer was stably maintained on the foot of the seawall with a foot protection effect.
