In the 2011 Tohoku tsunami, coastal urban areas were widely damaged by its huge hydrodynamic forces. However we have not fully revealed the huge tsunami hydrodynamic force acting on the structures. This is due to insufficient understanding on the relationships tsunami surge heights and shape of structure. When a huge tsunami strikes a uprigth structure, the tip of the tsunami runs vertically up the front face of the structure; herein, this phenomenon is called the tsunami jet flow. In response to the above background, this study aimes to improve the reproducibility of the tsunami water level fluctuation, by introduce dynamic contact angle to VOF model. It is found that the present model has certain accuracy on the reproducibility of the tsunami water level fluctuation.
