Abstract

Abstract

With 2-D water and substance's long-term transport velocities and their decomposed items,the observation data is analyzed on 1997 flood season in the Changjiang Estuary to give the separation character of suspended sediment,salinity and water's long-term transport.In the turbidity maximum,the average value of the angle between 2-D suspended sediment's long-term transport velocity and 2-D water's longterm transport velocity is 36.0°,and the average discrepant value of their speeds is 29.9%,so there is obvious separation character of suspended sediment and water's long-term transport.In the salinity front,the average value of the angle between 2-D salinityps long-term transport velocity and 2-D water's longterm transport velocity is 43.6°,and the average discrepant value of their speeds is 27.8%,so there is also obvious separation character of salinity and water's long-term transport.
