Abstract:

During the period from April 2002 to April 2003，markstakes and field observations were conducted on tidal flats in eastern Chongming Island of the Yangtze Estuary.The seasonal erosion and deposition cycle differed in southern part，east part and northern part.From spring to summer，the southern part was eroded，other parts were deposed；from summer to autumn，the northern part eroded，other parts deposed；on the contrary，from autumn to winter the erosion and deposition was different from other seasons；from winter to the following spring，the middle part was eroded，other parts deposed.Erosion and deposition were very much different in high tidal flat，middle tidal flat and low tidal flat in the same researching route.Based on the analysis of sediment grain size，suspended matter concentration in the water and other indicators，and on the examination of tidal variation data in the Yangtze Estuary，we found that the seasonal erosion and deposition cycle is closely linked to the morphology，suspended matter concentration in the water，hydrodynamics，tidal variation，wind direction，etc.But different effects may be observed in different parts and different seasons

Key words: Chongming East Tidal Flat, seasonal tide sedimentation, onthespot observation, effect factors
