Analyses of the velocity data at No. 14 Station of Chengjiawu channel for two tidal periods show that the ebb current is strong and that the flood current is weak.

陈家坞槽14号站位连续两个潮次的流速资料表明，该站位的潮流特点为落强涨弱。

The maximum current speed and SSC occour during spring ebb, and the minimum one occours during neap flood.

最大流速和含沙量都发生在大潮落潮，最小流速和含沙量都发生在小潮涨潮。

As the tide rises, a flood-tidal current moves in one direction and as the tide falls, the ebb-tidal current moves in the opposite direction.
