Abstract
Technique of covering sand by a fly ash beads has been established in sludge for one of taking measures the essential water environment improvement in the enclosed bay. However, there are few construction examples of the fly ash beads in the severe area.
In this study, wave height and current velocity was measured in the severe area. Moreover, real scale hydraulic model experiments were carried out using these results. Movement quantity were discussed by various kind of wave height and unidairectional current. Finally, the stability of artificially formed sea bed using fly ash beads were considerated.
