Abstract

The Song-Li region is located in the region where the downstream of the Lishui River converges with the Songzi River, the diversion channel for floodwaters from the Yangtze River to Dongting Lake. It is one of the areas most severely affected by flood disasters in the Dongting Lake region. Since the completion of the Three Gorges and its upstream basin reservoirs, its flood situation has changed with the evolving river-lake relationships. Constructing a 1D-2D coupled hydrodynamic model of the Yichang - Hankou area (including Dongting Lake and the downstream of Sishui River), we analyzed the flood levels and excess flood volumes in the Song-Li region under different typical flood conditions after the construction of flood control reservoirs in the Three Gorges and upstream basin. Besides, the existing flood control engineering system in the Song-Li region was also evaluated under current river-lake relationships and channel conditions. The results show that the existing flood control engineering system and reservoir operation have greatly improved the flood control situation in the Song-Li region. However, they have not fundamentally improved the tense flood control situation. The results of the study can also provide a reference for flood control and management in the Song-Li region.
