Overtopping flow velocity (OFV) and overtopping layer thickness (OTL) are essential parameters in breakwater design. Several empirical equations to predict these available many works of literature, but most the were derived based on impermeable structures such as sea dikes. In this study, we experimented with waves over a composite tetrapod armor units. experiments, wave was generated from regu...

A set of tools that is being developed for the automated inspection of rubble-mound breakwaters, as well as its application to the survey of Sines' west breakwater armour layer, are described. The results from the IRIS surveys are compared to those of the surveys carried out by the Portuguese Hydrographic Institute and first assessment of the structure evolution between 2000 and 2003 is made.

To share the construction and maintenance cost, an asymmetric oscillating water column (OWC) device integrated with a pile-fixed box-typed offshore breakwater is considered experimentally numerically. A fully nonlinear numerical wave tank established validated open source solver OpenFOAM. The effects of width draft rear box, incident height on energy conversion efficiency, reflection transmissi...

This paper presents the results from a numerical simulation study to investigate wave trapping by series of trapezoidal porous submerged breakwaters near vertical breakwater, as well seabed response around breakwater. An integrated model, based on volume-averaged Reynolds-averaged Navier–Stokes (VARANS) equations is developed simulate flow field, while dynamic Biot’s are used for simulating wav...

A plate-wave energy converter (pWEC) moored in front of a floating stationary breakwater is considered. The pWEC composed submerged flexible plate with piezoelectric layers bonded to both faces it. Hence the elastic motion excited by water waves can be transformed into useful electricity due effect. To evaluate performance breakwater-attached terms wave power absorption and attenuation, hydroel...
