Title: STUDY ON PERFORMANCE OF FLOATING BREAKWATER AND ITS NEW ARRANGEMENT
Abstract: Dynamic responses of two-dimensional and three-dimensional floating breakwaters have been discussed based onlaboratory experiments and numerical analysis. Two- and three-dimensional experiments have been conducted toinvestigate the dynamic behavior of floating unit for the floating breakwater. Wave height distributions have alsobeen measured in the experiments. The new type of floating breakwater arrangement has been proposed in thisstudy. Performance of proposed breakwater has been investigated. Numerical analysis has been carried out forboth two- and three-dimensional wave-floating breakwater interactions and validations of the analysis have beenexamined. Results show that the numerical analysis gives fairly good estimation of breakwater dynamics and wavedeformation due to breakwater. The floating breakwater arranged by the newly proposed method has beenconfirmed to reduce wave height behind the breakwater more than ordinal one.
