<p><P>PROBLEM TO BE SOLVED: To provide a movement control construction and movement control method for an underwater drift, and a structure used for the construction and method, which can transfer an underwater drift to the outside of a target area for inflow prevention using natural energy and basically requiring no operational cost. <P>SOLUTION: This movement control construction for an underwater drift generates a water stream to transfer the underwater drift in a direction away from a target area for inflow prevention by a wave energy by placing a structure 20 composed of plural triangular columns 10 in a predetermined length having an asymmetrical cross-section comprising a mild slope face 11 and a steep slope face 12, which are arranged in the lateral direction, on a water bottom and positioning the structure 20 with its normal line to the longitudinal direction of the triangular column 10 directed diagonally to a wave progress direction. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
