Computer Model for Energy Spectrum Transformation Over Irregular Bottom Topography.

Abstract

Based on the assumption that the wave energy associated with a narrow frequency band stayed within the band upon refraction, a numerical model based on finite difference method has been developed. This model, utilizing electronic computer, proves to be quite convenient to determine shallow water wave spectra at designated spatial locations of irregular bottom contours provided the deepwater wave spectrum is given. The model has been verified against analytical solution for case of two-dimensional parallel bottom contours and compared in good agreement with field measurement at location well beyond the surf zone.
