Model Tests on Wave Transmission Coefficient for Rubble Mound Structures With Superstructures

Abstract

The coastal structures, such as breakwaters, are constructed to provide the calm basin for ships and to protect the harbor facilities. The adequate design and the evaluation of design parameters are indispensable. The determination of crest height of coastal structures is one of the most important design process among all procedures. The allowable wave overtopping, the relative crest height (Rc/Hs) and the wave transmission could be applied to design the crest height of structures. The previous studies on the wave transmission coefficients were mainly conducted about the low crested structures. The previous design method could not cover the conventional breakwaters with superstructures. In this study, the wave transmission coefficient for rubble mound structures with superstructures would be investigated with hydraulic model tests.
