| Abstract: | The flow pattern near the non-submerged spur dikes were discussed. The experimental study on the flow characteristics of the spur dikes was conducted by mean of the advanced three-dimensional acoustics Doppler current meter. Time-average velocity and water surface characteristics were discussed from all aspects. The observed information showed that the flow was three dimensional and unsteady due to the fluctuating circulation zone and surface wave. |
