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...

Offshore structures are occasionally located at a relatively deep water region, the outside of breakwater. In this case, these structures may be damaged by the supposition of incident and reflected waves from a vertical breakwater. To prevent the damage, the reflected waves are controlled by installing porous structures at the face of the vertical breakwater. In this study, numerical experiment...

Now the last and most realistic problem will be investigated. This problem treats the breakwater as a rigid body that undergoes periodic wave forcing. This problem is the most realistic because a breakwater truly has physical dimensions in reality and would behave as a rigid body. Furthermore, if a breakwater is in the sea, then it will feel the effects of waves acting on it and not just the ef...

In the past decades, many references have studied the mechanics of meandering damage for breakwater. However, up to the present time, no model has been proposed to compute the consequence of this kind of damage quantitatively. So, this paper tries to solve this problem by combining the expected sliding distance technique and the diffraction model. 1 Preface The meandering damage of breakwater i...

The paper presents the results of a series of experiments conducted on physical models of Quarter-circle breakwater (QBW) in a two dimensional monochromatic wave flume. The purpose of the experiments was to evaluate the reflection coefficient Kr of QBW models of different radii (R) for different submergence ratios (d/hc), where d is the depth of water and hc is the height of the breakwater cres...
