Development of Numerical 3-Wave Interactions Module For Operational Wave Forecasts In Intermediate-Depth And Shallow Water

Abstract : The goal of the project is to develop an effective and numerically efficient implementation of 3-wave (triad) interactions for finite-depth wave models, in coordination with the project "Nonlinear and Dissipation Characteristics of Ocean Surface Waves in Estuarine Environments" funded by the Office of Naval Research (ONR) through the National Ocean Partnership Program (NOPP). The theoretical approach and numerical module, based on efficient stochastic formulations (e.g., Agnon and Sheremet, 1997), will be developed and tested following the same development cycle. The numerical module will be and comparison with accurate but computationally expensive pilot models, on a number of observational field and laboratory data sets. The module will be integrated and tested within operational model framework (e.g., WAVEWATCH III, STWAVE, SWAN, and others), in collaboration with operational code developers and other researchers working under the present NOPP program.
