A method for calculating the parameters of gravitational waves that interact with vertical permeable breakwaters, based on potential theory, has been developed and presented. The wave motion a fluid was described by velocity satisfies Laplace equation. shape surface components vector were determined. Numerical analysis influence permeability wall energy adsorption carried out. propagation in li...

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...

In the multifunctional system consisting of point absorber wave energy converters and a pontoon breakwater, breakwater plays an essential role in attenuating waves on lee side amplifying for better harvesting stoss side. The structure is expectedly improved to enhance its attenuation amplification at same time. Here we present novel parabolic arc show that range typical regular incident waves, ...

This research is conducted to examine the transmission wave and energy dissipation of a box culvert-type slotted breakwater, which designed as breakwater structure with watertight wall at top culvert type hole bottom. The process involves physical modeling this in laboratory. parameters are varied determine performance. results show that coefficient (KT) value reduced relative height (hL/d) dec...

The clarification on the collapse mechanism of a caisson breakwater has been an urgent task in order to reduce damages caused by next millennium tsunamis. In this study, piping destruction of a mound induced by seepage flow is taken into consideration solely. A stabilized ISPH method proposed by Asai (2012) is adopted with some modification associated with the extended Darcy law (Akbari 2013, 2...

A recent development of a parabolic equation method for wave propagation in a non-orthogonal coordinate system is reviewed. A transformation of the full governing equation prior to development of any approximation leads to a model whose results stand in closer agreement to laboratory data for a case of waves propagating into a breakwater harbor. The effect of amplitude dispersion on predicted w...
