Analysis on characteristics of hydrodynamic—sediment and calculation on distribution of suspended sediment concentration in Jiaoiiang Estuary DAI Wei-qi ,TAO Jian-feng ’。,ZHANG Qin。,ZHANG Chang-kuan ,XU Fan (1.State Key Laboratory ofHydrology—Water Resources and Hydraulic Engineering,Hohai University,Nanjing 2 1 0098,China;2.College ofHarbor,Coastal and Offshore Engineering,Hohai University,Na ng 2 1 0098,China) Abstract:Based on 5 group data of water and sediment of lfood and dry season in Jiaojiang Estuary from 2009 to 2014.the characteristics of hydrodynamic.sediment were ana!yzed.Four formulas between tidal current and sedi. ment concentration were obtained by means of empirical formula,and they were validated using results of numerical simulation.The results show that the flow field and sediment concentration of Jiaojiang Estuary are gradually in. creasing from the sea area to estuary,and the high concentration of suspended sediment iS accumulated from the sea area to Jiaojiang entrance.It shows a good relationship between suspended sediment concentration and flow.Based on these relationships and simulated flow field,the distribution of suspended sediment concentration agrees well with the numerical simulation results.
