- Abstract
- In this study, hydraulic model tests were conducted in the two-dimensional large wave flume and the threedimensional wave basin to understand wave run-up on different configurations of tetrapod-armored rubble mound coastal structures under the nonovertopping irregular wave conditions. The variation of wave run-up level depending on the number of Tetrapod layers and the incident wave angle are mainly focused in the experiments. The collected runup level data based on the different configurations of coastal structures were compared with the data presented by the previous studies. In a large wave flume, the experiments on variation of the number of armor layers were conducted to investigate the effect of armor layer thickness on the wave run-up. In a three-dimensional wave basin, the experiments on the wave run-up distribution along the curved section and straight section of the structure were conducted to figure out three-dimensional effects on the wave runup in terms of the incident wave angles and the configuration of the structure. Through the threedimensional hydraulic tests, the amplification of wave run-up at curved section of structure has been identified. On the other hand, the wave run-up level on the four-layer armored structure showed almost no big difference compared to that on the two-layer armored structure.
