Abstract
This study discusses the change in cross sections of bodies when artificial reefs made of crushed stones of mixed particle diameter are subjected to irregular waves. The author has found that the distribution of the frequency spectrum of transmitted waves depends on crushed stones constituting bodies. For a body consisting of one type of crushed stone, a larger deposition area of the crushed stone was found at the back of the crest of an artificial reef with smaller R. Under the same wave condition, the crushed stone No. 7 (S-5) of the erosion area of a body flows toward the onshore. However, the crushed stone No. 5 (S-20) of the erosion area of a body does not flow. These results show that the particle diameter and mass of crushed stones affect the stability of bodies.
