Breakwater/Submerged Breakwater


Breakwater refers to a dam built in the sea to keep the water surface in the harbor calm by blocking rough waves from the sea. When determining the structure of a breakwater, the most important thing to consider is keeping the embankment stable without damage from the waves. The effect of waves on the embankment can be estimated by first finding out the shape of the waves, and then surveying the wavelength, wave height and cycle.

Classification according to structure

There is the erection system (block type), inclined system (T.T.P.), and hybrid system (caisson).
Yujoo's method is the block-type Tiecell method.

Comparison of economic feasibility by construction method


A submerged breakwater is a breakwater whose upper part is below the average water level.
The most common coastal structures, such as a sand arrester and training dike, are breakwaters built parallel to the coast as coastal conservation facilities.
The purpose is to attenuate the energy of the wave at once by this submerged breakwater on the shore where a wave attack is strong to facilitate the defense of the coast itself, and to alleviate the erosiveness of the wave by smoothing the gradient of the wave that goes over it. It is also built to reduce public costs, avoid rapid seafloor fluctuations, and preserve the existing landscape.
