The effects of a seawall, a coastal dune, and the combination of both structures on the arrival time and inundation depth of tsunami waves running inland is determined experimentally in the laboratory. Seven structural cases are examined, acting tsunami with heights of the range from 2.2cm to 5.7cm. As a baseline, an experiment is carried out without any structures placed on the flume. The measured effects are seen in the inundation depths, reflected and transmitted tsunami heights. The results show that the combination of the seawall and coastal dune proves to be more effective and can be considered as a counter-measure against tsunami waves.
