Development and practice of the operation mode of "Storing Clear Water and Discharging Muddy Flow" in sediment-laden rivers in China
Sediment deposition in a reservoir constructed in a sediment-laden river has a direct impact on the reservoir's lifespan and its comprehensive benefits of flood control,power generation,navigation and water supply,In 1970s the reservoir operation mode of ‘Storing Clear Water and Discharging Muddy Flow’was put forward by Chinese scientists for coping with scrious sedimentation problem in the Sanmenxia Reservoir,and further applied and developed in several key water control projects such as the Xiaolangdi Reservoir on the Yellow River and the Three Gorges Reservoir on the Yangtze River.This operation mode successfully solves the problem of the conflict between sedimentation and benefits of a reservoir on a sediment-laden river by reducing its sediment deposition and maintaining its effective storage capacity for long-term use.It gives full play to the comprehensive benefits of a reservoir and presents an effective new way to cope with reservoir sediment problem for a sediment-laden river.The operation mode of ‘Storing Clear Water and Discharging Muddy Flow’ will be constantly optimized and improved in practice along with the knowledge deepening on reservoir sediment problems.Base on the actual situation of changes on runoff and sediment loads of rivers,the paper puts forward suggestions on further optimizing operation mode for the Three Gorges Reservoir and Xiaolangdi Reservoir to ensure the projects' safety and comprehensive benefits and to provide scientific support for promoting development on the theory and technology of reservoir sedimentation.
