Laboratory Investigation on the Behavior of Reef Breakwaters

Christos Antoniadis

An experimental investigation into the hydrodynamic behavior of reef breakwaters was carried out. The experiment aimed to provide full scale measurements of the main wave features at the front and rear of the breakwater, which have been analysed with variation of frequency and freeboard, for constant crest width and porosity. A series of tests was carried out at a 2-D wave flume. The analysis has shown that the reflection coefficient was a much more linear process than the transmission coefficient. The transmission coefficient was influenced mostly by the variation of the freeboard, in particularly, as the model became submerged.
