摘要
Abstract
In order to dispatch and utilize the flood storage scientifically and utilize the flood resources reasonably, during the trial impoundment operation of Three Gorges Project at 175 m water level, the scheme of dispatching the middle-small flood and advancing the impoundment to the end of flood season was implemented. The risks of flood control and sedimentation, and the ad-verse effect on the ecological environment are analyzed. The implementation standard for middle-small flood dispatch was set to control the flood risk, and the release discharge was controlled at right time to test the flood control capacity of downstream levee, so as to prevent the channel shrinkage and reduce the flood risk. Through carrying out sediment discharge dispatch in the flood season and the sedimentation reduction dispatch in the reservoir tail, a new dispatch mode of storing clear and releasing muddy is proposed. The measures of strengthening the experimental research and monitoring to mitigate the adverse affect on ecological en-vironment are put forward. It provides technical support for giving full play to the comprehensive benefits of Three Gorges Project and the risk control.关键词
