1.during the spring-tide , in the south channel it in flood tide is greater than that in ebb tide while in the north channel it in ebb tide is greater than that in flood tide;
2.time averaged SSCs during the flood are higher than during the ebb, with remarked temporal and spatial variations in the SSC and its vertical gradient.
3.According to ADCP data and suspended sediment concentration, suspended sediment movement in the Yangtze River Estuary is studied.
4.A Study of Suspended Sediment Dynamic Processes Based on Observations Using ADP and OBS in the Changjiang Estuary
5.alongshore,during the flood tide the suspended sediment concertration in the south channel is greater than that in the north channel while during the ebb tide it in the north channel is greater than that in the south channel.
6.Based on the study of sediment transport under the actions of tidal currents and wind waves, a mathematical model of suspended load and bed load for Yangtze Estuary is developed.
7.The marsh surface supplied water quantity accounts for 33% of the ebb water quantity in the creek,resulting in 20% of the ebb suspended sediment discharge in the creek during the ebb. This is a basic influence on the time asymmetry.
8.Application of Plane Two demension Suspend Sand Transfer And Diffuse Model In EIA of Water Way Dredging Projece
9.According to the analysis about the reflectance characteristics of suspended sediment water and the correlation coefficient between R and SSC, bands from 730~750nm, 800~820nm and 900~930nm were selected as the optimal wavelengths for the estimation of SSC.
10.Vertical distributions of average suspended sediment concentration of flood stage or ebb stage in the Nanhui nearshore waters of Changjiang Estuary fit to the Rouse equation: C yC a=hy-1ha-1 ωβκu *. The exponent (i.e. Rouse number) in the equation is a function of the settling velocity of suspended sediment and other parameters.
