Abstract: Abstract: The aim of this article is to investigate the wave transformations over a crescent shoal. Due to the nonlinear effects increases as the relative water depth decreases over a crescent shoal, Boussinesq equations were employed as the governing equations, and the finite differential numerical method was used in this study. The model is verified by the experimental results of Wu (2008). The result shows that the experimental result of wave height is larger than the numerical result and the wave focusing phenomenon is obviously observed. The phenomenon of the wave focus is still observed, and the wave height distributions of the numerical results get closer when the incident angle of waves increases. The wave focusing phenomenon is significant over a crescent shoal; also a trend for wave height gets larger and wave focusing gets more obvious as incident wave period increases.
