| Summary | Published in June 2003 IOT SERIAL No.92-81-760，116pp. Because of rapid increases of income and leisure time, more multi-recreational activities and facilities will be needed in Taiwan. Alternative seawalls should be proposed along the beach to meet the demand. The design of seawalls along the beach will be important in providing recreational and visual functions. This study focuses on the coastal protection and the optimum layout of seawall for recreational virtual function. Experiments, theory, and numerical model are carried out to study the propagation of monochromatic wave over a series submerged breakwater. The characteristics of Bragg reflection were investigated under the conditions including breakwater number (N), breakwater height (D), spacing interval (S), breakwater length (G), and incident angel ( ). The reflection coefficients of both experiments and numerical calculations were compared with other researchers’ laboratory measurements and models. Their discrepancies among those results were discussed. The results indicate that the effect of Bragg reflection can be greatly improved by increasing the number, height, and spacing interval due to the performances of series of submerged breakwaters. They can be provided as the references for the design of artificial bars to protect the beach in practice. |
