Numerical schemes used in this study is based on the Evolution Equation of Mild-Slope Equation (EEMSE) developed by Hsu et al. (2003). Effective sheltering parameter is presented to assess the effect of wave reduction reflection for a series of submerged breakwaters. HsinChu Gangnan Coast using the numerical approach and the project cost an example of application is focused on estimate is also present for a series of submerged breakwaters. Finally, the advantages and disadvantages of using a series of submerged breakwaters are then compared. The results can help serve as an appropriate choice in favor of a series of submerged breakwaters for practical design. |
