A large amount of driftwood debouched into the Bay of Beppu due to a great flood of the Ohno River which was caused by a heavy rainfall on July 2, 1990. The driftwood was generated by many landslides and river bank erosion. The driftwood debouched into the bay spreaded and arrived at several fishery harbors. A large amount of floating timber in the Bay of Beppu hindered the navigation of ships and damaged the fishery industries. In this study, the driftwood behavior debouched into the bay of Beppu is investigated by way of numerical simulation method. The effect of wind force on the driftwood motion is newly considered in the model.
