Study on Danjiangkou Reservoir's Integrated Scheduling and Maintenance of Environmental Flow in River Channel Downstream of Danjiangkou Dam

摘要

From the definition of environmental flows, the importance of maintaining environmental flows at downstream of the Danjiangkou dam is discussed. The variability characteristics of environmental flow elements since Danjiangkou Reservoir was operated, including hydrological regime in river channel the downstream of the dam, the spatial and temporal distribution of water, water quality, ecological environment and ecological environment, ecological water demand etc., are analyzed, and the scheduling manner of Phase-I project for Danjiangkou Reservoir and its existing shortages are analyzed as well. This paper proposes several comprehensive dispatching measures to maintain environmental flows downstream of Danjiangkou Dam.
