TLDR
In this article, the authors examined five years of wave measurements made in the South Atlantic Ocean and found that the occurrence of freak waves is actually more frequent than rare in the ocean.Abstract:
Contrary to the widely held notion that consid- ers the occurrence of freak waves in the ocean as being rare, from an examination of five years of wave measurements made in the South Atlantic Ocean, we found the occurrence of freak waves is actually more frequent than rare.read more

Laboratory measurements of limiting freak waves on currents
Chin H. Wu,Aifeng Yao +1 more
TL;DR: In this article, both dispersive spatial-temporal focusing and wave-current interaction are used to generate freak wave formation in a partial random wave field in the presence of currents.

On hydrological predictability
Günter Blöschl,Erwin Zehe +1 more
TL;DR: In this article, the authors argue that small uncertainties can easily amplify under certain conditions and will limit predictability, and they argue that there is a pattern to this and that the events were larger than what we thought could reasonably occur.

Virtual wave gauges based upon stereo imaging for measuring surface wave characteristics
Adam J. Bechle,Chin H. Wu +1 more
TL;DR: In this paper, a virtual wave gauge (VWG) technique based on stereo imaging is developed to remotely measure waterwave height, period, and direction, which minimizes computational costs by directly tracking the elevation of the water surface at selected points of interest using a Eulerian-based dynamic searching algorithm.

A σ-coordinate non-hydrostatic model with embedded Boussinesq-type-like equations for modeling deep-water waves
Chih-Chieh Young,Chin H. Wu +1 more
TL;DR: In this article, a σ-coordinate non-hydrostatic model, combined with the embedded Boussinesq-type-like equations, a reference velocity, and an adapted top-layer control, is developed to study the evolution of deep-water waves.

Mathematical aspects of extreme water waves
TL;DR: In this paper, the authors discuss mathematical aspects of extreme water wave generation in a hydrodynamic laboratory and choose the spatial nonlinear Schrodinger (NLS) equation as a mathematical model for this problem and concentrate on the study of one family of exact solutions of this equation that describes extreme wave events in a wave basin.

Nonlinear Four-Wave Interactions and Freak Waves
TL;DR: The theory of homogeneous four-wave interactions, extended to include effects of nonresonant transfer, compares favorably with the ensemble-averaged results of the Monte Carlo simulations as discussed by the authors.
