We consider the evolution of directional spectra of waves generated by constant and changing wind, modelling it by direct numerical simulation (DNS), based on the Zakharov equation. Results are compared with numerical simulations performed with the H

Transformation of spectral shape during wind wave development and the transition from the spectrum of developing waves to the spectrum of fully developed waves are well documented in measurements, but have so far escaped all modelling, as well as the

We study the long-term evolution of weakly nonlinear random gravity water wave fields developing with and without wind forcing. The focus of the work is on deriving, from first principles, the evolution of the departure of the field statistics from G

For historical and technical reasons evolution of random weakly nonlinear wave fields so far has been studied primarily in a quasi-stationary environment, where the main modelling tool is the kinetic equation. In the context of oceanic waves sharp ch

We develop a new approach to numerical modelling of water-wave evolution based on the Zakharov integrodifferential equation and outline its areas of application.The Zakharov equation is known to follow from the exact equations of potential water wave

The work is concerned with the fundamental problem of establishing limits of predictability of water wave evolution. The problem is addressed by simulating dynamics of waves on the free surface of heavy fluid using a new algorithm based on the integr

We consider three-dimensional crescent-shaped patterns often seen on water surface in natural basins and observed in wave tank experiments. The most common of these ‘horse-shoe-like’ patterns appear to be sporadic, i.e., emerging and disappearing

We consider nonlinear evolution of a random wave field under gusty forcing, fluctuating around a constant mean. Here the classical wave turbulence theory that assumes a proximity to stationarity is not applicable. We show by direct numerical simulati
