Features: This book provides an in-depth analysis of the main factors affecting the Tongguan high level, such as the sediment conditions of the Sanmenxia Reservoir from 1974 to 2000, the reservoir operation methods, and the scouring and deposition changes in the upstream and downstream reaches of the Tongguan section. It also discusses the principles of jet scouring and the mechanism of jet dredging in the Tongguan river section. Based on the results of indoor and outdoor jet scouring experiments, a jet dredging system and ship type suitable for the Tongguan river section are designed. According to the water and sediment conditions and river channel conditions, implementation plans and operational methods for dredging in the Tongguan river section are proposed. Through data analysis and numerical model calculations, the effectiveness of jet dredging in stabilizing and controlling the Tongguan high level is elaborated.
