碩士 / 國立中興大學 / 土木工程學系所 / 98 / The beach erosion of Hsin-she Coast, where located at the north shore in Fenbin Township of Hualien County, has been observed owing to the attack of several typhoons. Thus, a beach restoration project is currently under way. In this thesis, we attempt to investigate a feasible countermeasure for against the beach erosion by using Coastal Modeling System (SMC) which was developed by Cantabria University in Spain. First, the wave field, wave-induced nearshore currents and sediment transport for the current bathymetry were simulated for both the seasonal and typhoon wave conditions. The simulated results were verified well with the field investigations. Then, using SMC, a headland-bay beach was performed by a detached breakwater with nourishment. Based on the new bathymetry from simultaneous equilibrium in planform and beach profile performed from SMC, the numerical calculations using SMC on waves and nearshore currents were achieved. The designed new shoreline was compared well with the experimental investigation. Based on the results of this study, the headland-bay beach is a feasible option for the Hsin-she Coast.
