1TRANSPORT OF THE SUSPENDED SEDIMENT IN THE CHANGJIANG ESTUARY显示文摘The Changjiang River is characterized by the enormous volume of runoff and the great amount of sediment load with remarkable seasonal variation. The annual runoff sometimes is respondent to the amount of sediment load, and sometimes not. The amount of monthly sediment load after the month of the maximum runoff is larger than those before the month. The sediment concentration and net quantity of sediment transport in the vicinity of the river mouth varies greatly in time between the ebb and flood, spring and neap, and dry seasons and flood seasons. The three bifurcations also have differences in concentration and net quantity in space. Even in the same bifurcation they have differences in and out of the sand bar. At present, the North Channel is the main passage for water and sediment load emptying into the sea from the Changjiang River. More than 50 percent of the sediments from the river basin are deposited nearby the South Branch entrance and the main depositional area is situated in subaqueous delta off the South Channel. Between 122°30’E and 123°E is an important boundary for eastward sediment dispersion from which the suspended sediment are dispersed towards the east by south.SHEN Huanting Institute of Esturaine and Coastal Research, East China Normal University, Shanghai, China LI Jiufa Institute of Esturaine and Coastal Research, East China Normal University, Shanghai, China ZHU Huifang Institute of Esturaine and Coastal Research, East China Normal University, Shanghai, China HAN Mingbao Institute of Esturaine and Coastal Research, East China Normal University, Shanghai, China ZHOU Fugen Department of Marine Geology, Tongji Univcrsity, Shanghai, China 1992International Journal of Sediment Research1992,7,3:37
2The Bedload Movement in the Changjiang Estuary显示文摘- Sandwaves in the Changjiang estuary were measured with a shallow sediment profiler and an echosounder from 1978 to 1988. The data, together with grain size and bedform of sediment indicates that the bedload movement by rolling and saltation is of great significance to sediment transport and is the principal factor responsible for sandwave and sandbody development in the estuary. The sandwaves were found well-developed, which is related to the tidal range and the velocity of ebb current. However, the further growth is restricted by strong flood current prevailing in the estuary. Because of the significant bedload, the sandbodies shift obviously and frequently, and sometimes the exchange of position occurs between the sandbodies and tidal channels. As a result, ships are regularly forced to change their navigation course.Li Jiufa, Shi Weirong, Shen Huanting Xu Haigen and Doeke Eisma Associate Professor, Institute of Estuarine & Coastal Research (1ECR), East China Normal University, Shanghai200062 Professor, IECR, East China Normal University, Shanghai 200062 Professor, Netherlands Institute for Sea Research, P.

3THREE DIMENSIONAL MATHEMATICAL MODEL OF SEDIMENT TRANSPORT IN ESTUARINE REGIONS-A CASE STUDY OF THE HAIHE RIVER MOUTH显示文摘A 3-D numerical model for simulating tidal flow and sediment transport in the estuarine regions is presented in this paper. The model adopts -coordinate system and carries out -coordinate transformation to the basic equations, which ensure that all horizontal area has equal numbers of calculation points in vertical direction, this method provides higher distinguishable rate to the flow and sediment transport. Under the -coordinate system, the Galerkin finite-element method is applied for horizontal domain by using a new specially interpolating shape functions, while a finite difference approximation is employed over depth. The model can be used even in the situations with a considerable variety in the water depth in the computational domain. The model is verified by a test for which analytical solutions are available and then applied to simulate the tidal current and sediment transport of the Haihe River Mouth. A modeling system of sediment transport is established for applying to muddy estuary of North China. The comparison with the field data shows that the model can well simulate the evolution process in the estuary.BAI Yuchuan, SHEN Huanting, and HU Shixiong ( Asso.

4Distribution and fluxes of suspended sediments in the offshore waters of the Changjiang (Yangtze) Estuary显示文摘The offshore waters of the Changjiang Estuary are the transitional areas where river-supplied wa-ter and sediment are transported to the sea, and material exchanges occur with the neighbored Hangzhou Bay and the Jiangsu waters. Field observations of currents and sediment properties were conducted to study temporal and spatial distributions of suspended sediments under various dynamical conditions. The high sediment concentrations were found to occur in the western and southern waters of the offshore, and the low concentrations occurred in the eastern and northern waters. This pattern of the suspended sediment concentration (SSC) distribution is obviously influenced by the runoff and tidal current. The significant difference of along-estuary SSC distribution indicates that the SSC is reduced gradually from the west to the east, and that in the spring tide is obviously higher than in the neap tide. The methods of mechanism analysis and equal-area grids were used to calculate the suspended sediment fluxes at the typical cross sections. It was found that 44 percent of total suspended sediments from the Changjiang River were deposited in the submarine delta, and more than 27 percent of sediments were transported southernly into the Hangzhou Bay, and only 9 percent of sediments was supplied and exchanged with the northern Jiangsu waters, and about 20 percent of sediments was delivered offshore to the sea.WAN Xinning LI Jiufa SHEN Huanting 2009Acta Oceanologica Sinica2009,28,4:3
5Characteristics and generation mechanism of turbidity maximum in the Changjiang Estuary显示文摘Sediment convergence and resuspension are the two major mechanisms in forming turbidity maximum (TM) in the Changjiang Estuary. Sediment convergence is mainly controlled by the interaction between runoff and tidal current, the mixing of freshwater and salt water, the former forming tidal TM, whereas the latter forming brackish TM. The TM in the Changjiang Estuary is characterized by a combination of tidal TM and brackish TM, which varies temporally and spatially.Pan Ding’an Shen Huanting Mao Zhichang and Liu Xincheng (1.

14Study on the Improvement of Sea-Entering Waterway in the Changjiang Estuary显示文摘The Changjiang Estuary is the doorway of the Shanghai Harbour and the throat for the six provinces in the Changjiang River drainage area. However the minimum water depth of the waterway in the estuary is only about six meters, so that the development of the Shanghai Harbour and the utilization of water transportation on the Changjiang River have been greatly restrained. Since 1975, the depth of the sea-entering waterway of the Changjiang Estuary has been successfully increased by one meter. This article has made a comprehensive summing-up about the selection of waterways, the determination of the line for dredging and disposal of the dredged material, thus providing reference data for future work in increasing the depth of the waterway of the Changjiang Estuary and for controlling similar waterways of other estuaries.Shen Huanting , Xu Haigen Ma Xiangqi Professor, Institute of Estuarine and Coastal Research, East China Normal Universtiy, Shanghai Associate Professor, Institute of Estuarine and Coastal Research, East China Normal University, Shanghai Senior Engineer, Shanghai Waterway Bureau, Shanghai 1992China Ocean Engineering1992,7,3:0
15CHANNEL EVOLUTION AFTER THE CONSTRUCTION OF THE 1ST PHASE OF THE DEEPWATER CHANNEL PROJECT OF THE YANGTZE ESTUARY显示文摘In order to deepen the navigation channel, the Chinese government authorized the construction of the Yangtze Estuary Deepwater Channel Project in 1997. The project is divided into three phases, increasing the navigation channel depth to 8.5, 10.0, and 12.5 m stage by stage. The evolution of the North Passage after the construction of the first phase of the deepwater channel project is analyzed, based on surveyed topographic data. Then, the paper summarizes the comprehensive effect of the first phase of the project. Regarding hydrologic data monitored during the constructing process, the effects of the training dikes and groins on the riverbed erosion of the North Passage is studied. Finally, the evolution mechanism is analyzed and summarized. The evolution mechanism found can be helpful for regulation of other braided rivers or estuaries.Hualin WU Huanting SHEN Yonghong WANG 2006International Journal of Sediment Research2006,21,2:0
