Abstract


Appropriate seawalls can protect landside from tsunami inundation. But, in a case that a coastal industrial facility has an underground water channel, even if a seawall works properly against tsunami attack, sea water comes into landside via the channel. So, this study focused on tsunami inundation via an underground channel caused by tsunami. Numerical simulation methods were discussed and verified by using physical model test results.

Keywords
