| 摘 要： | 根据长江口ADCP实测断面水流资料,对长江口断面运动随时间变化情况进行了分析,结果表明,涨落潮流分离,落潮主流偏向右岸(南岸),涨潮主流偏向左岸(北岸),流速存在着明显的差异,低平潮和高平潮前后,在断面上有三个方向环流的产生。

| Abstract: | An analysis of the situation of sectional current movement with the change of time at the Yangtze River Estuary is carried out based on the real-surveyed data of sectional current with ADCP.The result shows that the currents of flood tide and ebb tide are separated,main current of ebb tide leans to the right shore(south shore),main current of flood tide leans to the left shore(north shore),flow velocities are different obviously,and circumfluences at three directions occur along the sectional direction. |
