Wave energy converters(WECs) integrated into floating breakwaters or, more generally, their designs also used as wave absorbers can provide a space- and cost-sharing solution to enhance the efficiency of coastal protection. In this study, hydrodynamic performances an oscillating buoy(OB)-type single-pontoon breakwater(SPFB) water column(OWC)-type dual-pontoon breakwaters(DPFB) are evaluated, re...

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...

A semi-empirical model for surf zone wave height decay is adapted to the parabolic equation method in order to include the effect of depth-limited wave breaking in combined refraction/diffraction calculations. Several examples for plane beaches are presented in order to show correspondence between the empirical model, its numerical formulation, and previous laboratory data. The model is then ap...

for prolonging the time that drug remains in stomach, new methods used as floating drug delivery systems, that available in various forms such as floating tablets. these systems enhance drug absorption and decrease plasma concentration fluctuations. iron deficiency and its inadequate absorption in diet are of community health problems. for prolonging the time that drug remains in stomach, new m...
