黄河口最大浑浊带特征及其时空演变

Characteristics and Evolutions of Turbidity Maximum at the Yellow River Estuary

根据汛期黄河口多船同步水文泥沙实测资料 ,对黄河口最大浑浊带特征及其时空演变进行研究 ,得出汛期黄河口最大浑浊带在整个潮周期始终存在 ,其含沙量和范围形态受潮相的控制 ,在落急和落平时最为发育。文中还探讨了黄河口最大浑浊带的形成机制 ,指出其形成主要受河流携带大量泥沙、泥沙异重流。

Characteristics and evolutions of turbidity maximum at the Yellow River estuary are studied according to the observed hydrographic and sediment data in the flood season It is concluded that turbidity maximum at the Yellow River estuary always exists during the whole tide circle in the flood season, and its sediment concentration, range and shape are controlled by tide The formation mechanism of turbidity maximum is explored, and it is pointed out that the actions of sediment density current, turbulence and density circulation cause the formation of turbidity maximum
