东江流域三大水库防洪与蓄水统筹分析

Integrated analysis of flood control and storage of the three major reservoirs in Dongjiang River Basin

东江流域新丰江、枫树坝、白盆珠三大水库汛期运行调度面临防洪与蓄水关系统筹问题,分析三大水库防洪与蓄水关键期,统筹上下游防洪安全,通过调洪演算得到防洪起调水位,结合水库调节性能考虑枯季耗水情况,综合确定最优库水位。相关成果可以作为三大水库运行调度、提高流域水安全保障的重要指导,并为其他具有控制性水工程的江河提供借鉴。

The relationship of flood control and water storage in three major reservoirs such as Xinfengjiang,Fengshuba,and Baipenzhu reservoirs in the Dongjiang River Basin needs a comprehensive consideration during flood seasons.Confirming the critical period of flood control and water storage in the three major reservoirs,and coordinate upstream and downstream flood security,via flood regulation routing to get a safe water level,combine the water consumption in dry seaon which considering regulation performance of reservoir,to finally get a optimal water level of the reservoirs.Relevant conclusions may be important guidance to the operation of the three reservoirs and improvement of the water security of Dongjiang River Basin.
