Application and discussion of detached breakwater in coastal protection

Coastal protection has become an important aspect of coastal engineering since coastal erosion is getting more and more serious.By reviewing some commonly used coastal protection methods,it is proposed that detached breakwater is an effective and widely applied approach.According to the research results at home and abroad,the protective mechanisms of emerged offshore breakwater are described in hydrodynamic processes,sediment transports and beach response.The empirical prediction formulas of beach response and the stable shoreline morphology models are summarized in the following part.Finally,the present studies of detached submerged breakwater are reviewed,and the protective mechanisms of submerged breakwater are preliminarily analyzed.Based on these analyses,some suggestions are given for the further researches of submerged breakwater in coastal protection.
