Their drift objects prevented the rapid elimination of obstacles and debris on land and sea. In addition, in areas where tsunami-fire occurred, accumulated wooden debris caused the large-scale fire spread. Generally, when assuming tsunami damages in urban areas, the inundation depth and arrival time of tsunami are mostly used. In order to enhance the tsunami damage assumptions in urban areas, to understand the characteristic of tsunami flow and the behavior of drift objects in urban areas is also important. However, it is very difficult to measure the state of actual tsunami flow and the behavior of drift objects by tsunami flow. This study aims to understand the characteristics of drift objects behavior in an urban area through a series of experiments in a laboratory flume. This study also validates numerical simulation model by comparing with the experimental results.<br><br><b>Recorded Presentation from the vICCE (YouTube Link): <a href="https://youtu.be/09KWpiVSbmU">https://youtu.be/09KWpiVSbmU</a></b></html> ER -
