... since the 1970s. These studies mainly concentrated on rigid body models. The theoretical design criteria of tethered-float breakwater for maximum power extraction from a general floating cylinder was reported by Mei (1976). Evans (1978) analytically studied the efficiency of a two-dimensional OWC device...

... countries (Lopez et al.(2013), several research studies have been conducted on its use as a hybrid structure that can be used as an integrated application (Doyle and Aggidis, (2019)). Later, OWC has been integrated with breakwater as a multipurpose/hybrid structure, as reported by Falcao and Henriques (2016...

... to defend different marine structures from wave attack. INTRODUCTION Researchers have developed impermeable breakwaters to defend coastlines and coastal infrastructure from wave attacks. These breakwaters span through the water depth (Abul-Azm, and Williams, 1997, Mondal and Alam, 2018), floating...

... vertical barriers with graded spacing for water waves. The effectiveness of this arrangement as breakwaters will also be tested. The 2D linear water wave theory will be used to model our problem, and the solution will be derived by using the boundary element method (BEM). Further, we will also look...

... to spread out of the bay due to the interception of the breakwater, but adhered to the south break water and the reclamation area instead. The surrounding area outside the breakwater was not affected by the oil spill. INTRODUCTION Oil spill has become a worldwide and the most destructive form...

... ABSTRACT A two-dimensional (2-D) numerical model is applied to study the wave reflection performance of perforated caisson breakwaters. The numerical model adopts a volume of fluid (VOF) method to track free surface and simulates the turbulent flow by using Reynolds Average Navier-Stokes (RANS...

... ABSTRACT Artificial reef (AR) can be regarded as a perforated breakwater when it performs as an auxiliary structure in beach nourishment. In this paper, a kind of artificial reefs made of cuboid reinforced concrete blocks, which has already applied practically in beach nourishment projects...

... ABSTRACT In this paper, an integrated numerical model is developed to investigate wave-seabed interactions around multiple submerged permeable breakwaters in an elasto-plastic seabed foundation with Bragg effects. In this model, the wave motion is governed by VARANS equation and the Biot's u-p...

... ABSTRACT This study presents results of numerical simulations on the effects of the presence of breakwaters on the OWC (Oscillating Water Column) performance. CFD (Computational Fluid Dynamics) simulations using a commercial code, Star-CCM+, are done for evaluating performances of the OWC...

... between them has the merits of lower reflection coefficient and smaller overtopping discharge and wave forces in comparison with a traditional non-perforated caisson (Jarlan, 1961). Thus, perforated caissons have been often used for building vertical breakwaters, seawalls and quay walls. A variety...

... Abstract In this paper, new formulae are presented to estimate the wave overtopping rate of mass-armoured berm breakwaters. In addition to the effects of dimensionless crest freeboard and crest width, the formulae consider the influences of water depth at the toe of the structure and structure...

... Abstract The evaluation of wave-induced excess pore pressure in the vicinity of marine structures is one of the key factors for coastal engineers involved in the design of foundation for the structures. Unlike previous models, the effect of outer shape of sloping seabed and breakwater...

... Abstract A horizontal plate breakwater is one of new breakwaters in coastal engineering. A suitably designed horizontal plate breakwater can significantly dissipate incident wave energy, and thus has good wave absorbing performance. The hydrodynamic performance of a submerged horizontal plate...

... Abstract Damage level of coastal structures has been scaled up according to the increase of wave height and duration of a storm due to the global climate change. Therefore the design criteria for a new breakwater are being intensified, and structural strengthening works are being also...

... ABSTRACT: In this paper, a physical experiment is conducted to investigate the wave overtopping flow thickness on the crest of slope breakwater and the generated secondary waves behind the slopping breakwater. The relationship between the relative overtopping flow thickness, secondary wave...
