A submerged flexible mound breakwater can be employed for wave control in shallow water as an advanced alternative to the conventional rigid submerged designs. This study presents a flexible breakwater with an innovative geometry based on model experimentation. Experimental studies were performed to compare the wave energy dissipation by the flexible mound and rigid structures, over a range of test conditions, for example, three different diameters of structure, three water depths, and different regular wave heights for three different beach slopes. Results indicate that the present submerged flexible mound breakwater is stable, being appropriate for most operational sea conditions. Large amplitude waves can induce significant motions of the structure; therefore, the interaction between radiating and scattering waves is highly contributing to the wave energy dissipation. The wave energy dissipation at breaking zone of the present submerged flexible mound breakwater is significantly greater than that of the other types of flexible and rigid formerly investigated structures.

波浪与水下柔性土墩防波堤相互作用的实验模型

作为传统刚性水下设计的先进替代方案，水下柔性土墩防波堤可用于浅水中的波浪控制。本研究基于模型实验提出了具有创新几何形状的灵活防波堤。进行了实验研究以比较柔性土墩和刚性结构在一系列测试条件下的波浪能量耗散，例如，三种不同直径的结构、三种水深和三种不同海滩坡度的不同规则波浪高度。结果表明，目前的水下柔性土墩防波堤是稳定的，适用于大多数操作海况。大振幅波会引起结构的显着运动；所以，辐射波和散射波之间的相互作用对波能量耗散有很大贡献。目前水下柔性土墩防波堤破碎带的波浪能量耗散明显大于以前研究的其他类型的柔性和刚性结构。
