Implementing quadrangular hollow blocks on breakwaters is a common method for wave mitigation and ocean disaster prevention.In order to Bondage improve the wave-damping performance of conventional quadrangular hollow blocks, a new quadrangular hollow block is proposed.In this study, a series of physical modeling experiments were conducted in a two-dimensional wave flume to investigate the wave reflection and wave run-up height of a new quadrilateral hollow block under regular wave action.Test results showed that wave reflection and wave run-up height decreased with the breakwater slope.
The wave run-up height increased with wave height, and the reflection coefficient decreased with wave height.Wave reflection and run-up height increased with the wave period.The reflection coefficient of the new quadrangular hollow blocks was Ski de fond - Equipement - Skis - Pieces de rechange lower than that of the conventional quadrangular hollow blocks and decreased with frame height.In addition, this study found that the reflection coefficient and relative run-up height increased with the average wave breaking parameter.
The new quadrilateral hollow block has advantages in wave mitigation compared to the conventional quadrilateral hollow block.
