This paper presents an experimental study of wave overtopping reduction by Rakuna-IV blocks placed in front of a vertical wall structure on a fringing reef. The experiment has been carried out in a 2D wave flume, where Rakuna-IV blocks are placed in front of a wave return crest seawall on a 1/100 slope fringing reef and 1/5 seaward slope. In this study, a series of irregular wave conditions in three water depth have been tested. In the results, the Rakuna-IV decrease wave reflections by half and effectively reduce wave overflow from 45% to 67% if there is no presence of the blocks. Next, the experimental data have been used to assess wave overtopping reduction by Rakuna-IV blocks. Last but not least, the influence of the relative crest freeboard, wave steepness, and shallowness of the reef on wave overtopping are presented.

摘要

This paper presents an experimental study of wave overtopping reduction by Rakuna-IV blocks placed in front of a vertical wall structure on a fringing reef. The experiment has been carried out in a 2D wave flume, where Rakuna-IV blocks are placed in front of a wave return crest seawall on a 1/100 slope fringing reef and 1/5 seaward slope. In this study, a series of irregular wave conditions in three water depth have been tested. In the results, the Rakuna-IV decrease wave reflections by half and effectively reduce wave overflow from 45% to 67% if there is no presence of the blocks. Next, the experimental data have been used to assess wave overtopping reduction by Rakuna-IV blocks. Last but not least, the influence of the relative crest freeboard, wave steepness, and shallowness of the reef on wave overtopping are presented.
