in this paper, a two-dimensional reynolds averaged navier-stokes (rans) model is developed to simulate the shoaling, breaking and overtopping of a solitary wave over a vertical breakwater. turbulence intensity is described by using a k turbulence closure model and the free surface configuration is tracked by volume of fluid (vof) technique. to validate the numerical model the simulation result...

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...

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...

Floating breakwaters are widely used due to their various advantages over stationary breakwaters. Lots of researches have been done on hydrodynamics and the type of bracing of these kinds of structures in recent years. In this study, numerical modeling of stresses caused by collision waves has been investigated. For this purpose, samples of floating breakwaters have been modeled in ANSYS softwa...

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...

A submerged horizontal plate type breakwater is pointed out as an efficient wave protection device for cage culture in marine fishery. In order to reveal the wave elimination principle of this type breakwater, boundary element method is utilized to investigate this problem. The flow field and the trajectory of water particles are studied carefully. The flow field analysis shows that: the intera...

Punta Langosteira port, located in A Coruña (Spain), was monitored during the winters of 2017 and 2018, measuring wave pressure crown wall structure. Furthermore, metocean variables were measured on a buoy very close to breakwater. This paper presents real pressures at breakwater different storm events. These values are compared with results application state-of-the-art equations for calculatio...
