Intercomparison Test Version of the SAIL Wave Model
In this chapter, a new wave prediction model termed discrete/hybrid, is proposed and tested, which incorporates parts of both Pierson—Tick—Baer (PTB)-type models and parametric models. It differs from the hybrid/parametric models in that the entire directional spectrum is banded and all bands are propagated. It differs from the PTB treatment of the source term in applying in banded space a parametric growth to model the effects of nonlinear wave—wave interactions. In the new model, each band is subjected to the greater of growth by a wind-wave instability mechanism consistent with the Abaco measurements, and parametric growth derived from an ε—ξ law (ε is nondimensional total energy; ξ is nondimensional fetch).
