説明

This study describes applicability of a numerical method to local scour by wave action around the pile-supported wave absorbing breakwater. CADMAS-SURF/3D(C-S/3D) was applied to the investigation which was performed by movable-bed models. In the present paper, basic application of CADMAS-SURF/3D was focused, since bottom shape was handled as fixed bed. The verification was achieved by comparing the velocity field of the calculation and the experiment. In the result, simulated value of the mean velocity was good agreement with experimental values, but simulated value of the maximum velocity was greater than experimental values. Moreover, it was not need to take a contracting flow effect by slit consideration in C-S/3D.
