Tsunamis are more effective in the run-up area at the shoreline. It was developed various measures to reduce tsunami damage. One of the tsunami protection is submerged breakwaters. In this study, it was investigated the effect of submerged breakwaters on tsunami run-up height as experimentally. Experiments were carried out in the glass-side wall wave flume of 22.5 m. length, 1 m. width, and 0.50 m depth at the Hydraulic Laboratory Istanbul Technical University. In order to determine the effect of submerged breakwaters on tsunami run-up height with various cases were used. Experiments were carried out for permeable and impermeable surfaces. Submerged breahwater's run-up height reduction conditions and percentages in comparison with the case without breakwater was given. It is shown that the effects of submerged breakwaters on tsunami run-up depend on submerged breakwater geometry. It has been obtained that submerged breakwaters will be an effective tsunami protection measure if it will save its structural stability.
