In the present work, we study the statistics of wavefields obtained from non-linear
phase-resolved simulations. The numerical model used to generate the waves models
wave-wave interactions based on the fully non-linear Zakharov equations. We vary
the simulated wavefield's input spectral properties: directional spreading function,
Phillips parameter and peak shape parameter. We then investigate the relationships
between a wavefield's input spectral properties and its output physical properties
via statistical analysis. We investigate surface elevation distribution, wave definition
methods in a nonlinear wavefield with a two-dimensional wavenumber, defined waves'
distributions, and the occurrence and spacing of large wave events.
