Abstract

<p> In the recent storm surge disasters, the outflow of cargos in harbors and the drifting of ships have been reported. Due to the wind force of typhoon, the behavior of drifting objects during storm surge would be different from that of tsunami. To understand the behavior of drifting objects is an important issue for disaster prevention because global warming is expected to increase the strength of typhoon in the future. In this study, we investigated the behavior of drifting objects around Nagoya Port under the potential maximum typhoon expected in the future. The numerical result shows that the drifting objects are strongly affected by the strong wind of the typhoon. By constructing the geometry model with consideration of building configuration and layout, it is possible to represent the behavior of objects trapped by buildings and drifting between buildings. In addition, for the purpose of use in the disaster prevention measure and education, we created the full 3D computer graphics showing the behavior of drifting objects based on the numerical results.</p>
