The behavior of a container drifting on an apron and moving to the sea due to tsunami run-up and sub-sequent drawdown reflected from a parapet is investigated using a three-dimensional fluid-structure-sediment interaction model. In terms of water surface elevation in front of the apron, inundation depth on the apron, and drifting behavior of the container, the predictive capability of the model is demonstrated against experimental data. Numerical results show that it can be determined from the vertical and rotational motion of the container with the landward velocity of zero whether the container finally moves to the sea. In addition, it is possible that a short wall placed in the vicinity of the parapet is effective as a countermeasure to prevent the container from moving to the sea.
