摘要
为充分发挥水库调度在防洪中的重要作用,文章以江西省信江流域为研究对象,结合该流域水文及天气特征,提出了利用天气系统及暴雨特性进行水库调度的方法。结果表明,在所提出的调度方法下,完成预泄后水位下降至77.21m,水位出现了0.89m的小幅度下降。同时到达的最高水位为78.40m,下降幅度为0.78m。说明该方法有效提高了水库的防洪能力,实现了优化调度,为流域内水库的防洪调度提供了新的技术参考。
In order to fully utilize the important role of reservoir operation in flood control,this paper focuses on Xinjiang Basin in Jiangxi Province.Considering the hydrological and weather characteristics of the basin,a reservoir operation method using weather systems and rainstorm characteristics is proposed.The results indicate that,under the proposed operation method,the water level decreased to 77.21m after pre-release,with a slight decrease of 0.89m.The highest water level reached was 78.40m,showing a decrease of 0.78m.These findings demonstrate that the proposed method effectively enhances the flood control capacity of the reservoir and achieves optimized operation.It provides new technological references for flood control operations in reservoirs within the basin.
