Research on Integrated Regulation of Three Flood Passages in the Jingjiang Reach of the Yangtze River
The flood passages in the Jingjiang reach of the Yangtze River are respectively the Songzi River, the Hudu River and the Ouchi River that act as flood passages to divert the flood on the Yangtze River to Dongting Lake for water storage and regulation. With a discharge capacity of as much as 25 percent of the peak flood of the Yangtze River, they are critical to flood control of the Jingjiang reach. Even after completion of the Three Gorges project, the flood passages still play an important role in flood control of the Jingjiang reach. However, the tensions in flood prevention, seasonal water shortage, etc. are conspicuous over the years. Flood prevention is still under the strain of heavy work though it has been alleviated after construction of the Three Gorges project. With the impounding of the Three Gorge reservoir and the erosion of the Jingjiang channel, the three flood passages dry up for a longer time, leading to more serious seasonal water shortage in this area. The three flood passages are badly in need of harnessing and improvement. In this paper, the scheme of controlling secondary branches and reinforcing main branches in combination with building plain reservoirs is discussed for the integrated regulation of the three flood passages, and its effect is also analyzed.
