Popis:	Field investigation on the effect and stability of gravel nourishment was carried out on the Jinkoji coast facing the Pacific Ocean. 33, 000 m3 of gravel was nourished on the shoreline, and subsequent beach changes were monitored by topographic surveys. Gravel layer was very stable while depositing along the shoreline. Fine sand layer on the shoreline was replaced by the nourishment gravel, leaving gravel layer below the fine sand layer as a foot protection in front of the seawall. A steep slope of 1/7 formed was effective to dissipate rough waves and to prevent wave run-up.
