Abstract : The purpose of this study is to develop a numerical method to compute shallow water wave spectral transformation both for stationary and non-stationary cases. A numerical model for stationary wave spectral transformation has been developed by Shiau and Wang (1977) and further amplified by Wang and Yang (1981). The present work extends the model to add bottom friction and local wind generation. This model is applicable to wave spectral transformation under stationary meteorological conditions. If the meteorological condition is non-stationary in the generating area or the local wind effect in the domain of consideration can no longer be neglected, such as when a hurricane or storm sweeps through offshore of a coastal region, the wave spectral transformation in shallow water should also be treated as non-stationary. A non-stationary wave spectral transformation model is thus developed to handle these cases. (Author)
