Dynamical Sedimentation in Qiantang Estuary

Jiang Guojun Zhang Zhizhong (Department of Geography)  
The dynamical sedimentation characters are discussed based on the dynamical and sedimental analysed results in Qiantang Estuary of Zhejiang Province. It is pointed out that the tide flow is the major sedimentational dynamics but during the flood term, the runoff also play an important role on the sediments deposition. It is suggested that the sediments are majorly composed by leap load except in the upper section of the estuary where there are also solid and suspended load which were deposited under the runoff action during flood term. The grain size parameters analysis show that there are clear reversion dynamic sorting deposition which developed under the tidal dynamics in Qiantang Estuary, but it is modified by the sediments from river basin and the dynamics of runoff in the upper section of the estuary.
