Probabilistic Neural Network for Predicting the Stability numbers of Breakwater Armor Blocks Doo Kie Kim1, Dong Hyawn Kim2, Seong Kyu Chang1 and Sang Kil Chang1 Summary The stability numbers determining the Armor units are very important to design breakwaters, because armor units are designed for defending breakwaters from repeated wave loads. This study presents a probabilistic neural network ...

Tsunami waves are often very energetic and therefore pose a significant threat to coastal structures. However, most defenses such as detached breakwaters designed protect against storm waves, with the consequence that tsunamis lead catastrophic failure of these This numerical study was inspired by wave scenario, which occurred at Soma Port in Japan, during 2011 Tohoku tsunami where combination ...

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...
