Abstract
Generally, wave transformation in shallow water should be estimated for a representative offshore wave spectrum. However it may be difficult for a Boussinesq wave model which requires a relative narrow computational region for calculating wave fields that an incident wave boundary is expanded to offshore. In this paper, multi-directional random waves are generated by using Boussinesq wave model on the linear incident boundary with several wave spectra transformed in shallow water. Wave height distributions behind a spherical shoal can be reproduced with spatial distribution of multi-directional spectra estimated by an energy balance equation. In an actual harbor, the significant wave height in front of a revetment can be estimated larger in generation with several wave spectra.
