| 摘 要： | A three-dimensional transportation model for suspended solids （SS） in Zhujiang （Pearl） River estuary, South China, was developed by coupling with a three-dimensional hydrodynamic model. The model was validated using hourly measured data of sediment contents during 25-26, July 1999. The results showed that modeled contents matched well with measured ones and that the modeled top layer distribution agreed with the remotely sensed image of suspended solids in summer. The modeled results showed clearly the layers of suspended solids in depth, with larger sediment contents in lower layers though in the interface between salt water and freshwater the lowest contents appeared in middle layer. In overall, the suspended solids inflow from 8 rivers,transport southwestward, and carried by strong coastal flow in Zhujiang River estuary. Contours of sediment contents in the estuary spread further to the open sea during ebb tide rather than flood tide which reflects that the suspended solids in the estuary are land sourced.

| Abstract: | A three-dimensional transportation model for suspended solids (SS) in Zhujiang (Pearl) River estuary, South China, was developed
by coupling with a three-dimensional hydrodynamic model. The model was validated using hourly measured data of sediment contents
during 25–26, July 1999. The results showed that modeled contents matched well with measured ones and that the modeled top
layer distribution agreed with the remotely sensed image of suspended solids in summer. The modeled results showed clearly
the layers of suspended solids in depth, with larger sediment contents in lower layers though in the interface between salt
water and freshwater the lowest contents appeared in middle layer. In overall, the suspended solids inflow from 8 rivers,
transport southwestward, and carried by strong coastal flow in Zhujiang River estuary. Contours of sediment contents in the
estuary spread further to the open sea during ebb tide rather than flood tide which reflects that the suspended solids in
the estuary are land sourced. |
