碩士 / 國立成功大學 / 水利及海洋工程學系專班 / 92 / This study explores the major factors leading to coastal erosion at Shuang-Chun coast in Tainan County, and it has collected previous researches on coastal changes as well as the field data of wave climate reported by related units in this region for reference. The protection program for erosion includes installation of three offshore submerge breakwaters, piling, fencing, beach nourishment suggested by Tainan Hydraulics Laboratory, NCKU.
Numerical models are applied to analyze the changes of wave field and nearshore current field after the construction of offshore submerge breakwater, so the effect of the program can be evaluated. Results reveal the obvious decrease in wave field, nearshore current field after the construction. Therefore, the mitigation of beach erosion can be achieved due to the protection. As the instability of upstream and downstream beach will be caused by coastal structure’s intervention, successive survey should be followed in the future.
