Examining the Combined effect of the berth and draft of Pontoon-type floating breakwater on the variation of wave transmission coefficient by using numerical modeling

In this study, the combined effects of berth and draft of Pontoon-type floating breakwater on the variation of wave transmission coefficient is examined. To find the width and draft of both floating breakwater on the wave transmission coefficient, three draft 0.8, 1 and 1.2 meters wide and five 2.4, 4.8, 7.2, 9.6 and 12 m were examined. Average for periods of 2, 2.5, 3, 3.5 and 4 seconds, and the range of 0.2 to 1.2 m wave height analysis was performed. According to analysis done by the software ANSYS AQWA and the results showed that the coefficient of wave transmission by increasing the width and draft breakwater float dramatically reduced So that the wave transmission coefficient for breakwater width 2.4 m, draft 0.8, from 0.88 to 0.34 breakwater width is 12 meters and draft 1.2.
