Breakwaters are the important and the costly ones of the marine structures. Composite breakwater is one of the common types in the world. Because of the progress in marine industry in Iran in recent years, designers have noticed this structure. Because of the sensitivity of composite breakwater to environmental conditions, also construction costs, difficulty of repair and maintenance and import...

Owing to the advantages of assuring best views and seawater exchange, submerged breakwaters have been widely installed along eastern coast Korea in recent years. It significantly contributes promoting advancement shorelines by partially inhibiting incident wave energy. Observations were carried out a pressure-type gauge Bongpo Beach evaluate coefficients transmission via breakwater, results obt...

A novel two-dimensional numerical wave tank based on the two-phase Navier–Stokes equations (NSEs) is presented. The popular projection method applied to decouple pressure and velocity fields, while solutions are uniquely enhanced by a newly-developed immersed-boundary generalized harmonic polynomial cell (IB-GHPC) for Poisson equation, which lies at heart of method. GHPC method, originally prop...

Low-crested and submerged breakwaters are frequently employed as coastal defence structures. Their efficiency is governed by wave energy dissipation, the transmission coefficient can evaluate this parameter. The current study conducts experimental investigations on both low-crested exposed to different conditions compare their performance with that of emerged breakwaters. provides a comprehensi...
