| Abstract | ||||
| The efficiency of the floating breakwaters was experimentally studied under normal and regular waves with wide ranges of wave heights and periods. The efficiency of the breakwater is presented as a function of the transmission, reflection, and dissipation coefficients. Different parameters affecting the breakwater efficiency such as, the connection of the virtical plates under the floating body at different positions, length of mooring wires and the wave length were tested. It was found that, the transmission coefficient decreases with the increase of relative breakwater width (B/L), the number of plates and also with the increase of the relative wire length (l/h) whereas the reflection coefficient takes the opposite trend. In addition, the suggested floating breakwater system dissipates about 15% to 30% from the incident wave energy. Also, the suggested floating breakwater model is efficient compared with other types of pontoon breakwaters. | ||||
