Many of the coastal conservation facilities of the fishing port were severely damaged by the wave force of the 2011 Tohoku earthquake tsunami. We evaluated the tsunami wave force by conventional hydrostatic pressure for the sea wall of the fishing port. In addition, we considered the acting force and the acting range for the water apron of the sea wall during tsunami over flow, and presented a reasonable design of the sea wall. The tsunami wave force for the sea wall is not sufficiently examine by the seabed gradient, the position of structure and the back slope of the sea wall.

The 2011 Tohoku Earthquake Tsunami ran up the height of over 40 m and covered over 560 km2 of the coastal land area in Tohoku, Japan. The tsunami destroyed many structures and killed over 15,000 people. Appropriate measures should be taken against the next giant tsunami to avoid such tragedy. The generation mechanism of wave force is uncertain when a tsunami wave running on land collides with a structure. Especially, the fluid motion of a tip of tsunami wave immediately after the collision with a structure is very complicated. The information of the pressure distribution acting on the structure is necessary to construct buildings in the coastal hazard area. The purpose of this study is to clarify the relationships between the fluid motion and pressure variation by a dam-break flow as a tsunami flow on a dry bed colliding with structures.
