Features: This book is a specialized work on the sedimentation issues in the middle reaches of the Yangtze River and the Dongting Lake region. It systematically and comprehensively studies the dynamic changes of water and sediment in the area, analyzing the main factors influencing flood disasters in the middle reaches of the Yangtze River and the Dongting Lake region. The book is divided into 8 chapters, analyzing the current status and evolutionary characteristics of the main stem of the Yangtze River and the three-mouth diversion channels, as well as the current status and sedimentation patterns of Dongting Lake. It examines the impact of the reduction in Dongting Lake's storage capacity on flood levels in the middle reaches of the Yangtze River and the Dongting Lake region, as well as the effects of the ( refers to the process of cutting meanders in the river channel) in the Jingjiang system on sedimentation in the main stem of the Yangtze River and the diversion of sediment through the three mouths. Mathematical models are used to reproduce the evolutionary process of the river-lake relationship over the past 50 years, and the trends of the river-lake relationship after the operation of the Three Gorges Reservoir are simulated, analyzed, and predicted. The book also explains the current flood control status and the main reasons for the rise in water levels in the middle reaches of the Yangtze River and the Dongting Lake region, and studies relevant governance measures and countermeasures. The book is well-documented and rich in content, serving as a reference for design, research, planning, and teaching personnel in fields such as channel evolution, river channel regulation, flood control and disaster reduction, and water and sediment resource allocation.
