Abstract

Coastal areas have many benefits for activities, such as port construction, fishing activities, recreation areas, resource utilization, alternative energy-producing places, etc. However, many factors limit this use due to water wave activity, such as storm surges and the potential for tsunamis. These factors also cause abrasion and coastal erosion that can damage the coastal environment. To overcome this problem, it can be done by building a coastal protective structure, one of which is a floating breakwater. In this study, analysis of wave transmission on a hexagonal floating breakwater will be carried out to determine the effectiveness of its performance. The wave transmission test on the floating breakwater was carried out with variations of irregular waves (Jonswap spectrum) and mooring angles. The position of the wave probe is set at 100 cm and 220 cm behind the structure. The largest transmission coefficient occurs at a mooring angle of 30 o in both scenario 1 and scenario 2. The smallest transmission coefficient value is at an angle of 60 o in both scenarios of wave probe placement. The plotting results show that the transmission coefficient is directly proportional to the period and height of the incident wave and vice versa the transmission coefficient is inversely proportional to the steepness of the wave
六角形浮式防波堤波浪传输特性分析
沿海地区对活动有许多好处,如港口建设、渔业活动、休闲区、资源利用、替代能源生产场所等。然而,由于水波活动,许多因素限制了这种使用,例如风暴潮和潜在的海啸。这些因素还会造成磨损和海岸侵蚀,从而破坏海岸环境。为了克服这个问题,可以建造一个海岸保护结构,其中一个是浮动防波堤。在本研究中,将进行波浪在六边形浮动防波堤上的传输分析,以确定其性能的有效性。对浮动防波堤进行了不规则波(Jonswap谱)和系泊角度变化的波浪透射试验。波探头的位置设置在结构后面100厘米和220厘米处。在场景1和场景2中,最大的传输系数出现在系泊角为30°时。两种测波方式下,透射系数值最小的角度均为60°。绘制结果表明,透射系数与入射波的周期和高度成正比,与入射波的陡度成反比
