Abstract

Some of the influencing variables for the structure design are wave run-up and run-down. Run-up wave can be used as the variable in determining the coast structure crown height and run-down wave influences the structural damage. The objective of this study is determine the run-up and run-down performance on breakwater with different angle of wave direction. This study is carried out by means of irregular non-breaker waves on physical modeling. The spectrums used on irregular wave is Bretschneider, employing tetrapod, cubes, and rubble mound as the armour layer. The results of this study showed that the parameter which influence on the occurring run-up and run-down height at breakwater influenced by wave period (T), incoming wave of height (H), armour layer, water depth (d), and angle of wave direction (θ). 0o and 15o, , the run-up result tends increased or the same at the angle of 0o and 15o in all protection layer unit. While at 30o, tetrapod and broken stone tends increased and cubes tends decrease. Similar results are obtained for run-down.
