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.

结果表明，研究区净悬沙通量自杭州湾内向外海迅速变小，悬沙总体由杭州湾向外海输运，但同时存在向杭州湾方向的净输沙；研究区基本处于水动力平衡带，悬沙输运具有往复搬运、净输沙量小的特点；平均流输运、Stokes漂移输运和垂向净环流输运是引起悬沙泥沙净输运的主要作用机制，自口门至外海，平流输运作用逐渐减弱，垂向净环流输沙在悬沙净输运中所占比例逐渐增加；舟山群岛海域既是杭州湾向东海输运泥沙的重要通道，也是东海沿岸流携带泥沙向南输运的过渡地带；研究区单颗粒泥沙沉降速度很小，远小于絮凝沉降速度，在研究本区悬沙沉降时必须考虑絮凝的影响。
