Analysis of river regime evolution in the Yangluo Waterway of the Yangtze River in Wuhan
The Yangluo Waterway is located in the Wuhan section of the Yangtze River,characterized by a straight to slightly meandering river segment.A construction project for a long-distance shipping terminal is planned in this area,necessitating an analysis of riverbed evolution.This paper is based on a long series of measured hydrological and sediment data,providing an overview of the historical evolution of this river section.It focuses on recent changes in the river segment,including variations in the thalweg line,sandbars,deep channels,and flow distribution in areas such as Tianxingzhou.The paper presents a detailed discussion of the evolving conditions in the project river segment,including changes in the thalweg line,deep channels,and typical cross-sections.The results indicate that,with stable upstream water and sediment input and consistent hydraulic conditions,the riverbed in the Tianxingzhou channel and the Yangluo Waterway will remain relatively stable.After accounting for the impact of the Three Gorges Project regulation,there will be minor sedimentation in the left channel of Tianxingzhou,but the overall river morphology will remain unchanged,and the Yangluo Waterway's riverbed will remain essentially stable.
