The distribution of wave heights and periods for seas with unimodal and bimodal power density spectra
… wave heights and the heights and periods of the extreme waves are also studied. Seas are classified by the shapes of their power density spectra. Spectra with a single peak are designated as unimodal and spectra with two peaks as bimodal. Seas are further classified by spectral width, a function …

Statistics of amplitude and fluid velocity of large and rare waves in the ocean
The understanding of large and rare waves in the ocean is becoming more important as these rare events are turning into more common observances. In order to design a marine structure or vehicle to withstand such a potentially devastating phenomenon, the designer must have knowledge of extreme waves …

Cavity dynamics of water entry for spheres and ballistic projectiles
… Industrial applications include ship slamming, extreme waves and weather on oil platforms, sprayed adhesives, paint aerosols and ink jet printing. In the field of naval hydrodynamics there is particular interest as these problems relate to the study of the water entry of mines and bullets, and …

On the use of Statistical Downscaling for the Study of Coastal Hazards in the Pacific
… spatiotemporal scales (e.g., water levels, waves), caused by different triggers such as tropical cyclones or distant source swells. Quantifying very low probability events from observations, results in analysis highly dependent of the length of the record, and even when available records may …

SPH Modeling of Solitary Waves and Resulting Hydrodynamic Forces on Vertical and Sloping Walls
… the accurate prediction of the impact of an extreme wave on infrastructure located near shore is difficult to assess. There is a lack of established methods to accurately quantify these impacts. Extreme waves, such as tsunamis generate, through breaking, extremely powerful hydraulic bores …

Numerical and asymptotic modeling of evolving nonlinear ocean surface wave fields
… model for the evolution of nonlinear ocean waves, including extreme waves known as Rogue/Freak waves. Due to their elusive and destructive nature, the media often portrays Rogue waves as unimaginatively huge and unpredictable monsters of the sea. To address these concerns, derivations of …

A study on green water problem with dam break model and the BIV technique
The green water generated by extreme waves is primarily an air-water mixture, which includes a continuous phase and a dispersed phase. The continuous phase is explored with the dam break model by three main approaches, namely analytical, experimental and numerical. Analytically, both the Eulerian …

Characteristics of the wave energy resource at the Atlantic marine energy test site
… wave energy. Additionally, observations of the extreme wave conditions that have occurred at the site and estimates of future storms that devices will need to withstand are presented. The implications of these results for the design and operation of wave energy converters are discussed. The …

Towards Rogue Wave Characterization in False Bay, South Africa
Rogue waves are extreme oceanic waves which exceed twice the significant wave height of the wave record. In False Bay, South Africa, a shallow sea mount called rocky bank was suggested by Shipley (1964) to be the cause for increased wave energy along the eastern periphery of False Bay, where it is …
