宝口站“2013.08”特大洪水流量确定

摘要

受强台风“尤特”登录影响，白盆珠水库流域发生了超百年一遇特大洪水。该文采用水位～流量关系、 Q～A R关系、比降-面积及瞬时单位线等方法推求白盆珠水库上游宝口站洪峰流量，并对推求的结果进行对比分析，以确定合理的洪峰流量。其分析成果可为今后流域开发治理、工程规划设计、防灾减灾等工作提供参考。%Affected by Typhoon Utor make landfall , a flood of 100 years recurrence encountered in Baipenzhu Reservoir Basin .Peak flow of Baipenzhu reservoir upstream Baokou station has been calculated by the methods of stage -discharge relation , Chezy formu-la, roughness for and instantaneous unit hydrograph .With comparative analysis on the calculation results , the reasonable peak flow has been determined .And the results can be reference for the development and treatment of river basins , engineering program de-sign, disaster prevention and reduction and mitigation work in the future .
