The processes of dynamic sedimentation in the Changjiang Estuary

The characteristics of the mouth bar and subaqueous delta, and the water ma sses and water systems in the Changjiang Estuary and nearby coastal waters are examined. The hydrodynamics of the estuarine plume, and the fronts and turbidity systems are described with reference to their distribution and mo vement. Physical, chemical, biological and geological barrier effects of th e estuarine mouth bar are evaluated. Through examination of the sediment di stribution, sedimentation rate and depositional sequence, the sediment exch anges and evolution of the estuarine mouth bar and subaqueous delta are des cribed.
