The purpose of this paper is to test the feasibility and affectivity of Bragg breakwaters on increasing wave energy by using wave conditions. The Bragg reflection phenomena will depend on the wavelength of surface waves and the spacing of the submerged breakwater. The spacing of the submerged breakwater is the most important parameter for designing a series of submerged breakwaters. In this paper, the Hybrid Mild-Slope Equation model (HMSE) was applied to calculate the phenomena of Bragg reflection and the feasibility and affectivity of ocean power. The data comprising wave records from three harbors in Taiwan during 1999 to 2004 were used to illustrate performance of this model. The effect and feasibility of Bragg breakwaters were also assessed in the practical cases. From the calculated results, the average of the ocean power comes to be 2.54 times more than the original condition in Keelung Harbor, 2.5 times in Su-Ao Harbor and 2.4 times in Hualien Harbor.
