Session C.6: Tsunami Impact

How do you initiate a tsunami in the laboratory?

A steady overflow was generated by using a submersible pump. The height of the sea-side water level was changed by varying the height of the overflow weir installed on the sea-side of the breakwater model.

Have you considered different parapet shapes (i.e. angle of the back) and how it affects flow?

In this study, only the parapet shape which is commonly used in Japan was targeted. As you pointed out, it seems that overflow discharge and flow speed behind the parapet will change depending on parapet shape.

Have your recommendations been implemented? Have you analysed other ports in Japan?
