Pattern of Wave Height Changes Around of Pontoon's Floating Breakwater

Abstract

The main goal of using floating breakwaters is to provide a sheltered area of calm water in a coastal zone. In the present research, for analyzing the hydrodynamic modeling of pontoon floating breakwaters, the AQWA module of ANSYS was selected. The main parameters that have been considered in this research are the patterns of significant wave height, wave period, and draft and the width of floating pontoons. Wave transmission coefficient can be obtained from water surface changes in any point of the leeward. Results of the numerical modeling demonstrate that a pontoon floating breakwater with a relative width of greater than 0.4 has an appropriate performance. Also, it has been found that the transmission coefficient of pontoon floating breakwaters will be in the range of 0.35 to 0.60 if the relative wave period changes in the range of 1.5 to 4.
