Abstract

The Songli area of Dongting Lake is an important link between the Yangtze River and Dongting Lake, located in the two provinces of Hubei province and Hunan province in China. The water system conditions in the Songli area are extremely complex. The Songzi River, which passes through the area, connects with the tail end of the Li River, supporting each other, resulting in severe floods in the region throughout history. Since the completion of the Three Gorges Dam, there have been significant changes in the erosion and sedimentation of the riverbed in the Songli area. It is necessary to use newer terrain data to reproduce historical floods and study the flood control situation in the Songli area under the changed terrain conditions. Therefore, this article uses a hydrodynamic model to study the current flood control situation in the Songli area after the completion of the Three Gorges project, and proposes three possible flood control and control schemes. The analysis results show that compared with the construction of Yichongqiao Reservoir and the use of flood detention areas, the Songzi Gate has a better effect on flood control in the Songli area. The research results of this article can serve as a reference for subsequent comprehensive governance projects in the Songli area.
