Abstract
There are high risks that tsunamis may cause containers stored in ports to drift into sea/land areas. In this study, a simulation model for container drift behavior was constructed to enable accurate prediction of the drift behavior of containers and its collision force. The applicability of the model was confirmed by calculations reproducing previous container drift experiments. The results showed that it is possible to reproduce the collision force when containers drift and collide with walls at the back of the container storage area due to differences in the container weight, container length and rigidness of the wall for the supercritical flows on an apron.
