The study aims to verify the feasibility and the effectiveness to enhance application of Bragg reflection for researching the wave energy of seas around Taiwan. Comparing the increase of magnitude and the distribution of wave energy in conditions of both with and without the Bragg reflection, the incident wavelength and the spacing of series submerged breakwaters are the most critical design parameters for the conditions of Bragg reflection. The study collected and analyzed wave data of seas around Taiwan at observation stations of Keelung, Hualien, Suao, Taipei, Taichung, and Anping for the duration of 1999-2004 for determining probability distribution of wave height and period. The analysis results are used for the setup of Bragg reflection effect of series submerged breakwaters by further applying the Hybrid Mild-Slope Equation (HMSE) for researching increased wave energy.
Results of the probability analysis of the original average wave energy are as follows: Keelung Harbor, 1.1 kw/m; Suao Harbor,: 0.6 kw/m; Hualien Harbor, 1 kw/m; Taipei Harbor, 0.55 kw/m; Taichung Harbor, 1.8 kw/m; and Anping Harbor, 0.19 kw/m. After setting up series submerged breakwaters for generating Bragg reflections, the average wave energy increased up to 2.54 times of the original. For observation stations on the east, the wave energy of Keelung Harbor increased to 2.8 kw/m, 2.54 times of the original; that of Suao Harbor increased to 1.5 kw/m, 2.5 times of the original; that of Hualien Harbor increased to 2.4 kw/m, 2.4 times of the original. For observation stations on the west, the wave energy of Taipei Harbor increased to 1.3 kw/m, 2.36 times of the original; that of Taichung Harbor increased of 3.2 kw/m, 1.7 times to the original; and that of Anping Harbor increased of 0.32 kw/m, 1.68 times to the original. East coast of Taiwan in accordance with the above results, is more suitable for the development of wave energy environment, you can increase efficiency considerations the setting of the series of submerged breakwaters.
