The processes of dynamic sedimentation in the Changjiang Estuary

The characteristics of the mouth bar and subaqueous delta, and the water masses 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 movement. Physical, chemical, biological and geological barrier effects of the estuarine mouth bar are evaluated. Through examination of the sediment distribution, sedimentation rate and depositional sequence, the sediment exchanges and evolution of the estuarine mouth bar and subaqueous delta are described.
