水流交汇现象普遍存在于自然界和人类工程的多种水力系统中，交汇河段水流泥沙特性的研究对防洪规划、航运交通和生态环境等均具有重要意义。从流场分区、水面形态、螺旋流、水流结构、能量损失及泥沙特性等方面较为系统地总结了近70年来干支流交汇河段水流泥沙特性的研究成果，并对未来发展前景进行了展望。
水流交彙現象普遍存在于自然界和人類工程的多種水力繫統中，交彙河段水流泥沙特性的研究對防洪規劃、航運交通和生態環境等均具有重要意義。從流場分區、水麵形態、螺鏇流、水流結構、能量損失及泥沙特性等方麵較為繫統地總結瞭近70年來榦支流交彙河段水流泥沙特性的研究成果，併對未來髮展前景進行瞭展望。

As the confluence of different channels is common in the natural rivers and hydraulic pro- jects, the study of its flow and sediment characteristics are very important on flood control, navigation and ecosystem. In this paper, the researches on characteristics of water surface condition, spiral flow, flow structure, energy loss and sediment transport at the confluence of open channels in the past 70 years are reviewed, and the development prospect is also discussed.
