摘要：

河流交汇区是河网系统中水、沙、污染物、生物等环境要素的突变点,也是河网行洪与污染物输移扩散的关键控制节点。从野外测量、室内试验与数值模拟方面,总结分析了河流交汇区水流结构与污染物输移的基本特征及其在不同交汇条件作用下的响应规律,以及复杂水流结构与生境对于河流交汇区水安全的重要影响。展望了未来研究重点,建议加强非恒定流条件下的交汇区水力学特性研究,进一步揭示交汇区污染物掺混输移特征与水动力条件之间的响应机制,研究通过工程布局与水力优化调控相结合的措施系统提升了交汇区防洪安全与水生态环境质量。

Abstract:

River confluences are areas where environmental elements such as flow structures, sediment deposition, water quality, and organisms undergo significant changes in river networks, and are the key nodes for flooding and pollutant transport. This review summarizes the basic characteristics of flow structures and pollutant transport at river confluences and their responses to different conditions, along with the important impacts of complex flow structures and habitats on water safety issues in previous field measurements, laboratory experiments, numerical simulations, and theoretical studies. Future research should focus on enhancing the understanding of the hydraulic characteristics of river confluences under unsteady flow conditions, further clarifying the response mechanisms between pollutant transport and hydraulic parameters, and improving the flood safety and the water ecological environmental quality through the combination of engineering layout and hydraulic optimization and regulation.

Key words: river confluences, flow structures, pollutant transport, water safety
