Abstract
Coastal vegetation not only provides efficient wave attenuation, but also serves to protect and restore the ecological environment, making it a favorable coastal protection measure. Composite breakwaters are a traditional engineering measure with good wave absorption performance. Accordingly, a plant-ecological composite breakwater is proposed. The effects of changes in the emergent and submerged lengths of rigid vegetation on the attenuation of wave run-up on the composite breakwater were investigated using experimental measurements. Cylinders were used to simulate vegetation in the experiment, neglecting their vibration. The results indicate that vegetation can effectively attenuate wave run-up. At larger wave heights, the maximum wave run-up is more sensitive to the submerged length of vegetation, with an attenuation rate of up to 44.6%. At smaller wave heights, the maximum wave run-up is more sensitive to the emergent length of vegetation, with an attenuation rate of up to 23.6%, which decreases with increasing wave period. Furthermore, there are systematic changes in the overall wave run-up trend occur over time for different conditions.
