| 回水顶托现象普遍存在于世界各大河湖之中，常导致河流上游河段壅水，易在丰水期引发洪涝灾害，威胁河流两岸人民群众的生命财产安全。受顶托河道水流运动复杂、影响因素较多，研究其水流运动特征随各影响因素的变化规律，对流域防洪、港口航道开发及河湖综合治理具有重要意义。从受顶托河流水流运动基本特征及其影响因素、河道水流运动特征对顶托的响应规律、河道水流受顶托程度表征方法等方面，对当前该领域国内外研究成果进行总结，对存在的不足与研究趋势进行分析，提出尚需深入研究的重点方向，以期为受顶托影响下的河道水流运动特征及其综合治理研究提供参考。 |

| The phenomenon of backwater is commonly observed in major rivers and lakes worldwide,often leads to upstream water stagnation and increasing the risk of flooding during high-water periods,which threatens lives and property of people living along the riverbanks.The complex variations in river flow movement characteristics caused by backwater effect,influenced by numerous factors,studying its hydrodynamic patterns and impacts is crucial for flood control,port and waterway development,and comprehensive basin management.We preliminarily analyze and summarize domestic and international research findings in this field,focusing on three aspects,such as the fundamental characteristics and influencing factors of rivers affected by backwater,the hydrodynamic responses of rivers to backwater,and methods for quantifying the degree of backwater influence on water flow.Additionally,we analzye research gaps and trends,propose key directions for future research,which can provide insights and references for studying river flow movement characteristics under backwater effect and comprehensive regulation. |
