In a circulation water channel, drift tests of physical model floes were performed in order to investigate characteristics of their motion and interaction with the structure. The floes were driven by the wind and the current. The floe motion near the structure depends on the structure and the floe shapes. When the structure stops both the floes and water, the floes slow down their speed in front of the structure and the interaction force on the structure decreases, compared with the case when the structure stops only the floes. Disk floes shown a lateral motion in front of the structure. They flow out from both sides of the structure. Rectangle floes, however, have no motion in front of the structure. The disk floe motion and the rectangle floe motion can be regarded as the two extreme cases of real pack ice motions. An actual pack ice motion may be between these two extreme cases.
