Abstract

Abstract

On the basis of measured mud fluid data in the Northern Channel of Changjiang Estuary in China,the periodical changes of mudfluid are discussed.It is thought that the mudfluid changes in three kind of periods in the Northern Channel of Changjiang Estuary.It is pointed out that the tidal period is influenced by the tidal velocity change,at which the flood current erodes the mud fluid and results in the mud fluid scale reducing and the slack current makes fine sediments flocculation and deposition and results in the mud fluid scale increasing.The semi-monthly changes of the mud fluid are controlled by the am ount of fine sediments supply.The annual period change of the mud fluid is controlled by the water temperature,which controls the fine sediments flocculation in the Changjiang Estuary.The annual change of sediment supply and the dynamics are also important influencing factors.
