Modelling of Non-Linear Quadruplet Wave-Wave Interactions in Operational Wave Models

The aim of this paper is to examine deficiencies of the widely used Discrete Interaction Approximation (DIA) for the computation of non-linear quadruplet wave-wave interactions in operational wave prediction models. Its sensitivity to the frequency resolution of the wave spectrum is illustrated by means of a simple wave growth experiment. An improved DIA is presented in which a second wave number configuration is added to the existing DIA.
