Abstract

Submerged breakwaters provide beach protection by dissipating the wave energy for shoreline erosion abatement without destroying beach aesthetics. The geometrical characteristics of the structural design of the submerged breakwater determine its stability. Wave magnitude propagation in the actual physical sea state conditions, particularly wave period, height and depth, are vital factors that dictate wave transformation. Laboratory experiments in a controlled systematic programme are modelled in the condition of monochromatic unidirectional wave to present coefficient of transmission (Ct) as the reference index of breakwater wave energy dissipation for the effect of wave period, significant incident wave height and structural narrow crest width. The test results indicate high wave suppression and structural friction to wave motion, where Ct values tend to decrease with the increment value of relative wave period, significant incident wave height and relative narrow crest width.
