Abstract

In recent years,the hydrodynamics and riverbed topography of the Changijiang River Estuary isinevitably experiencing some new changes due to the decrease of the runoff and sediment load.Successive 9-days fixed point observations during neap-mean-spring tide show that the sediment content was relatively lowfor neap tide,increased with the increase of flow velocity and was higher for spring tide,which indicatedevident sediment resuspension.Analysis of the observed data gave out empirical formula of sediment carryingcapacity of neap,mean and spring tides for the South and North Channels of the Changijiang River Estuary, and showed good correlation between the sediment content and tidal current, and also good correspondence oftheir power changes.

Key words

Changjiang River Estuary / South and North Channels / flow velocity / sediment content / sedimentcarrying capacity / variation of runoff and sediment discharge
