Study on the Floodwood and Suspended Trash Drifting in Sakata Port

Abstract

The marina in Sakata Port was blockaded with the floodwood and suspended particles, and the blockage was deemed to be caused by the flood from Mogami River in July 2004 and the typhoon that approached the port in August 2004. In consideration of phenomena obtained from the interviews with the port managers, etc. and the records of the damage, numerical simulation was conducted with calculation of currents, waves and winds. The typical movement of suspended material under the two natural phenomena was reproduced with the simulation.
