漳河水库汛限水位浮动控制运用的探索

Floating control of flood water level for Zhanghe Reservoir

依据漳河水库流域实时水雨情信息及水文、气象预报成果,采用上、下浮动控制运用的办法,对水库汛期限制水位实行实时动态管理,并建立了非线性数学模型及解算方法,探讨可能存在的风险因素、风险程度与实施条件.运用实践证明,水库年均增加蓄水量0 32亿m3,既避免了单一追求水库兴利效益而忽视水库防洪安全的倾向,也避免了单一强调水库安全而忽视兴利用水的需求,较好地解决了水库防洪安全与兴利蓄水之间的矛盾.

Based on the results of real-time weather, rainfall and runoff forecasting for the Zhanghe River basin, a dynamic management method-the floating flood level control was carried out in the operation of the Zhanghe Reservoir.The influencing factors and the degree of the risks of the method and the conditions of its implementation were discussed by establishment of a non-linear mathematical model and its solution. Practice shows that the average annual increase of water storage of the reservoir reaches 32 million m^3. The present method effectively settles the contradiction between the safety of reservoir flood control, water conservancy construction and water storage.
