两因素同时校正法推求河道洪水流量

对于受洪水或变动回水单因素影响的河道流量整编已有相应的水力因素型方法，但对测站受洪水和回水混合影响的水位流量关系曲线的处理，是水文整编中一个尚未解决好的课题，本文在对校正因素法和落差指数法地深入分析的基础上，指出了落差指数法整编受洪水影响的水位流量关系曲线时存在的问题，提出了解决受洪水和回水混合影响的河道流量整编方法－两因素同时校正法，并着重叙述 该方法的原理及使用步骤，奉节站，湘潭站等资料的验证

River Discharge Data Derived by Two Simultaneously Corrected Factors Method

or the compiling of streamflow data influenced by flood or backwater there exist corresponding methods, but the handling of stage-discharge relation affected by flood and backwater remains unsolved. On the base of analysis of the correction factor method and drop index method, this paper points out the existing problem in the drop index method for the compiling of the stage-discharge relation affected by flood and backwater and puts forward a new method-two simultaneously corrected factors method.The paper describes the principle of the method and the calculation steps. The verification of the data of Fengjie station,Xiangtan station and so on shows clearly that the present method can improve the precision of discharge data compilation. Furthermore,it speeds up calculation.
