Abstract

Abstract

Based on the observation data of current velocity, sediment concentration, grainsize and combining the result of simulation, to analyse the trend of sediment transport and erosion and deposition of the bed.In the whole research region, the sediment concent ration increases gradually from the seashore to the of fshore area.The north is higher than the south, and the north-east of estuary is highest; The grain size of bed reduces gradually from the seashore to the off shore area, and the north is lower than the south; The decharge sediment of convey is the most source deposition, and the bigger erosion region in the south of riverway and seashore.The wind has prominent effect on sediment transport in this region: the sea water is clearing eneral whether, but it change turbid in the big wind whether.The sediment deposit rapidlyafter wind, and the sea water changes clear again.The simulation result shows the sediment concentration is 9 mul tiple bigger in wind than no wind.
