| Abstract |
Wave runup is one of the most important factors affecting the design of coastal structure exposed to wave attack. In this study, two dimensional laboratory tests were conducted under the different random wave conditions and structure configurations to develop a formula to predict runup heights. Rubble-mound structure consisted of tetrapod armour blocks with 1:1.5 and 1:2 slopes. The relative water depths (the ratio of the significant wave height to water depth at the toe) ranged from 0.14 to 0.56. The formula proposed here is applicable to surf similarity parameter ranging from 2 to 6. Runup heights on 1:2 slope were higher than those on 1:1.5 slope. Runup heights were reduced by 5% when the armour layer thickness increased two times. |
