VISION AND PROBREMS FOR REFLECTION OF EFFECTS OF LONG-PERIOD WAVES INTO DESIGN OF COASTAL FACILITIES

Abstract

The long-period waves have been researched in recent years because of its importance in the various problems of coastal engineering, such as long-period oscillation, long-period motions of moored vessels, sediment transport, wave-overtopping and stability of coastal structures. Importance of long period waves have been well recognized, however, its reflection of effects of the long-period waves into design of coastal facilities is not sufficient.
In this paper, we review previous researches on the long period waves and consider the problems in the reflection of effects of long-period waves into design of coastal facilities.
