Protecting coastal communities has become increasingly important as their populations grow, resulting in increased demand for engineered shore protection and hardening of over 50% of many urban shorelines. Shoreline hardening is recognized to reduce ecosystem services that coastal populations rely on, but the amount of hardened coastline continues to grow in many ecologically important coastal ...

A 2D numerical investigation of the power absorption a constrained wave energy hyperbaric converter (WEHC) under full-scale sea conditions is presented. fully non-linear model DualSPHysics, based on coupling smoothed particle hydrodynamics (SPH) fluid solver with multibody dynamics solver, used to interaction between and WEHC sub-systems. The was first validated against experimental data for si...

A numerical study was performed in the present work about an Overtopping Device Wave Energy Converter (OTD-WEC) with one and two ramps incorporated a real breakwater. The Constructal Design method applied to evaluate effects on average dimensionless overtopping flow of degrees freedom device ramps. In addition, comparison carried out among different geometry configurations OTD-WEC determine whi...

The Rockefeller Wildlife Refuge, located along the Chenier Plain in Southwest Louisiana, was location of sequential landfall two major hurricanes 2020 hurricane season. To protect rapidly retreating coastline a system breakwaters constructed, which partially completed by Multi-institutional, multi-disciplinary rapid response deployments wave gauges, piezometers, geotechnical measurements, veget...

When an offshore or port breakwater is constructed on a coast, beach erosion often occurs nearby beaches of the due to wave diffraction effect associated with formation wave-shelter zone, because longshore sand transport triggered from outside inside zone. Similarly, when unidirectional blocked by breakwater, will occur downcoast. In these cases, movement key factor. Another aspect arisen manag...

Abstract In carrying out its supply chain activities, a project often experiences problems starting from the procurement, production, to delivery processes. Likewise, Makassar New Port Breakwater development must consider risks in planning, implementation and operations. This study aims determine that could potentially occur activities at Indonesia. Furthermore, it will provide information on w...

There are currently at least five aircraft runways built on the reclaimed coral sand foundations in South China Sea (SCS). The seismic dynamics and stability of revetment breakwaters nearby lands with SCS deserve attention. Taking reclamation engineering as background, this study performed several centrifuge shaking table tests (N = 50 g) to explore a breakwater runway foundation. It is reveale...

Wave energy resources are enormous and widely distributed worldwide evaluated as to replace fossil fuels. One of the methods collect wave is using a point absorber device, which device designed react sensitively movement water surface for harnessing energy. This paper about influence fixed breakwater on Wavestar-shaped pivoted converter (WEC) computational fluid dynamics (CFD). The may generate...

A wave is an energy that can propagate with a medium; the propagation of moves respect to time by carrying velocity per unit time. Sea waves are one propagating problems broken down produce relatively inhomogeneous minimum amplitude and speed sea waves, which have their own difficulties in solving them numerically. This study aims analyze stability on submerged breakwaters. research will approx...

Abstract The hydrodynamic characteristics of a Bragg breakwater with triple vertical plates in monochromatic regular waves are experimentally studied. two spacings between the every adjacent denoted by S 1 and 2 respectively which both wide enough for necessary reflection, is equal or unequal to . A series experiments carried out wave flume equipped piston-type generator, performance analysed v...
