CMS-Wave is a two-dimensional spectral wind-wave generation and transformation model that employs a forward-marching, finite-difference method to solve the wave action conservation equation. Capabilities of CMS-Wave include wave shoaling, refraction, diffraction, reflection, transmission over structures, depth-limited breaking, dissipation, wave-wave interaction, wave-current interaction, and wavestructure interaction. Wave diffraction is implemented as a diffraction term in the energy-balance equation and is derived from the parabolic wave equation. CMS-Wave can be used in either in a half- or full-plane mode, with primary waves propagating from the seaward boundary toward shore. It can calculate wave run-up, wave setup, and overtopping of structures. Shoreward and seaward reflections are treated using the mirror reflection principle. In applications to large areas, a feature of the model that facilitates nesting multiple grids may be used with two or more model grids. A larger grid with a coarse resolution may be used to simulate the regional processes while a smaller grid with fine resolution can be applied to more complex bathymetry and shoreline geometry in the local area. For large domain applications and long-term simulations, CMS-Wave can be run in a fast mode with multiple processes to expedite the model computations.
