TOMAWAC is a third generation spectral wave model for sea states evolution from the oceanic to the coastal scale. It models the spatial and temporal evolution of the directional spectrum of wave energy, providing a high-level description of the sea state. TOMAWAC can be used to model a large number of physical processes, including the generation of waves by the wind, their propagation over very large distances on an oceanic scale, and the effects of water depth variations as waves approach the shore (refraction due to variations in bathymetry and/or an ambient current field), the many processes that dissipate wave energy (white-capping, wave breaking due to bathymetry, bottom friction, attenuation by porous media or vegetation) or redistribute wave energy within the spectrum via non-linear transfers between wave frequencies (among 4 or 3 waves). The wind fields supplied as input forcing data, as well as the characteristics of the marine environment (sea level, ambient currents) can, in the general case, be spatially and temporally variable. TOMAWAC can be used for several types of application, including wave climate simulation based on wind fields (from meteorological reanalyses or atmospheric forecast models), on the scale of a few days (storm) or several decades (wave hindcast database), wave propagation studies in coastal areas, by transferring sets of known wave conditions off a site to the coast.
