【摘要】：通過實(shí)時觀測黃河口洪季(9月)潮灘潮周期內(nèi)懸沙濃度和波潮流等水動力因素的變化,并結(jié)合邊界層懸浮物剖面測量儀(ASM-4)數(shù)據(jù),討論了懸沙濃度在潮周期內(nèi)的變化及其影響因素,計算了再懸浮通量、分析了懸沙濃度的垂向分布特征。結(jié)果表明,一級海況下海流對再懸浮的貢獻(xiàn)較大,二級海況下波浪對再懸浮的貢獻(xiàn)較大。觀測點(diǎn)懸沙濃度多以濃度峰的形式出現(xiàn),既有潮流沖刷床面所引起的懸沙濃度峰,也存在由波致再懸浮和潮流輸運(yùn)所引起的懸沙濃度峰。
[Abstract]:The changes of hydrodynamic factors such as suspended sediment concentration and wave current during the tidal cycle of the Yellow River Estuary during the flood season (September) are observed in real time, and the data of the boundary layer suspended matter profiler (ASM-4) are combined. The variation of suspended sediment concentration in the tidal cycle and its influencing factors are discussed. The resuspension flux is calculated and the vertical distribution characteristics of suspended sediment concentration are analyzed. The results show that the current has a great contribution to the resuspension in the first order sea condition, and the wave to the resuspension in the second order sea condition. The suspended sediment concentration in observation points appears in the form of concentration peaks, both caused by tidal current scouring bed surface, and also by wave-induced re-suspension and tidal current transport.
