| Abstract: | Based on the Rouse formula, the suspended sediment characteristics of vertical distribution is
studied and analyzed by data measured and collected in the Yangtze estuary, and the applicability of the formula
Rouse is verified. The difference between the settling velocity of sediment calculated by Rouse formula and the
actual sediment settling velocity is clarified. Using the sediment vertical distribution of measured data in the north
channel, the relationship of the unbalanced empirical formula of sediment coefficient and vertical average sediment
concentration is established, based on which, an empirical formula of vertical distribution of suspended sediment is
established and verified by measured data. |
