Intensive wave reflection occurs when the wavelengths of incident waves and bottom undulations are in a 2:1 ratio. Existing studies have included Bragg resonance phenomenon passing over continuous undulating parallel to oblique shoreline. More generally, mechanism is used as means coastal protection, rather than power generation. To focus energy specific area, here, we propose sinusoidal sandba...

Nonlinear internal waves are an upper ocean phenomenon that drives horizontal surface current gradients, which in turn modulate waves. Under certain conditions, this wave-current interaction creates roughness heterogeneity, the form of alternating rough/smooth bands. In study, we investigate sensitivity modulation effect to wave properties and develop sea states using simulations individual sol...

The water particle velocity of the wave peaks is closely related to load borne by offshore structures. It great value for marine disaster prevention study nonlinear extreme waves represented Freak waves. This applies High-order Spectral Method (HOS) numerical model analyze characteristics and influencing factors peak with two different generation mechanisms under initial condition a weakly modu...

This extended abstract contains two topics: stability of a pitched rock slope (in contrast to randomly placed rock) and mitigation excessive wave overtopping at an existing slope. The single layer could reasonably well be predicted by the Van der Meer formula. criteria for start damage failure, however, become much stricter armour layer. commonly used EurOtop-equations were fit influence factor...

Freak waves have the properties of strong nonlinearity and suddenness, which are often accompanied by extreme weather conditions. As an important environmental load, wind has a significant transient characteristic plays role in generation freak waves. In order to understand statistical under action wind, especially influence on waves, laboratory experiments were carried out. this paper, based B...

Ocean motions at frequencies of the internal wave band are generally associated with freely propagating waves that supported by stable vertical stratification in density. Previous analyses yearlong current observations from Bay Biscay showed a finestructure semidiurnal tidal and near-inertial higher harmonics fills spectrum. Here, simple model is presented forced nondispersive forward energy ca...

Rogue waves are a recognized but not fully comprehended hazard of major concern to the maritime industry. There is one agreed-upon unified model that explains formation such and little known about their frequency occurrence. This study used in situ data from wave buoy located at entrance Tampa Bay, Florida, assess conditions could lead development these potentially destructive waves. Bay commer...

Two commercial Navier-Stokes solvers are applied to wave-wave and wave-structure interaction problems leading to the final application of simulating a single float of the wave energy converter (WEC) Manchester Bobber in extreme waves and a fixed section of the Pelamis in regular waves. First the two software packages CFX and STAR CCM+ are validated against measured results from physical tank te...

We review several historical landslide tsunami events and perform a set of numerical experiments to investigate the particular effects slide shape on impulsive waves generated by subaerial solid slide. The computational model is based OpenFOAM, which solves 2D RANS formulations with volume fluid method used capture air–water interface. consider triangular prism shaped slides in our introduce pa...

We present a study of the physical characteristics traveling waves at shallow and intermediate water depths. The main subject is to influence nonlinearity on dispersion properties waves, their limiting heights steepness, shape solitary etc. A fully nonlinear Serre–Green–Naghdi-type model, classical weakly Boussinesq model fifth-order Stokes wave solutions were chosen as models for comparison. a...
