Settlement characteristics are studied based on formula of suspended sediment settling velocity and previous research results. Results show that the suspended sediment flux quickly decreases from the Hangzhou Bay to the offshore area. Although the suspended sediments are primarily transported towards the offshore area, net transport towards the Hangzhou Bay is also found in the study area. The study area is basically located in hydrodynamic balance belt, and the suspended sediment transport is characteristics of reciprocating movement and small amount of net sediment discharge. The net suspended sediment transport is mainly controlled by average current transport, Stokes drift-induced transport and gravitational circulation transport. The advection transport effect gradually weakens and gravitational circulation transport evidently intensifies from Hangzhou Bay to the offshore area. Settling velocity of single particles is far smaller than that of floccules, so, influence of flocculation of suspended sediments must be taken into the consideration.

流体自旋流器上端给入并在旋流器内形成强制旋转流,旋转流将颗粒按粒度和比重分为内外环层,当矿浆流动至锥体部分时,由于锥体的突然变向,阻力增大,颗粒群向下运动的趋势减缓,并在此形成旋转悬浮层,随着离心力场的减弱,重力作用越来越明显,由按粒度和比重分成的内外两层逐渐转化为按比重分选的上下两层,比重大的颗粒通过底流口排出,比重小的颗粒则通过溢流管排出,从而实现轻重颗粒间的分离。
