A nonlinear triad interaction source term for wave forecasting models (INVITED)

Abstract eng:
Quasi-2D deterministic and non-local stochastic evolution equations are derived for water waves up to quadratic nonlinearity. The models include nonlinear shoaling and wave breaking effects. The work identifies that the stochastic model should be localized in two different manners in order to account for two nonlinear resoant mechanisms related to intermediate and shallow water regimes. The locallization process allows a 2D nonlinear triad source term (S3nl ) fitting for implementation in wave forecasting models to be formulated by locally using a quasi-2D approach. The derived formulation presents good agreements with deterministic ensembles, field measurements and laboratory experiments.
