摘　　要：为解决马斯京根法在河道洪水演算中未考虑河道断面特征和水力特性的变化问题,在淮河中游吴家渡至小柳巷河段、滹沱河中游黄壁庄至北中山河段采用考虑河道断面几何形状和水力学糙率的Muskingum-Cunge-Todini可变参数法和非线性水库法进行河道洪水演算研究,探讨考虑河道断面特征和水力特性的演算方法在湿润区淮河中游及半干旱区滹沱河中游的适用性,并将模拟结果与马斯京根法进行比较。结果表明,Muskingum-Cunge-Todini可变参数法和非线性水库法在研究河道上模拟精度较高,洪峰合格率均在86%以上,确定性系数均大于0.8,可应用于河道洪水预报。Although the Piecewise Muskingum method for river flood calculation has been widely used in China,the major limitation that hinders the further application of the Piecewise Muskingum method within distributed models still needs to be addressed.This method with empirical parameters cannot consider the impact of changing river cross-section characteristics and hydraulic roughness on the flood computation.In this study,the Muskingum-Cunge-Todini variable parameter method and the non-linear reservoir method,which could consider the channel cross-section geometry and hydraulic roughness,were used in the river flood calculation in the middle part of Huaihe river,from Wujiadu to Xiaoliuxiang,and the middle part of Hutuo River,from Huangbizhuang to Beizhongshan.In addition,the river flood calculation with the Piecewise Muskingum method also has been conducted as a comparison.Initial tests indicate that the Muskingum-Cunge-Todini variable parameter method and the non-linear reservoir method have high simulation accuracy in the studied cases.The correct rate of flood peak is above 86%,and the coefficient of certainty is greater than 0.8.This study can provide references for the flood calculation considering the change of the channel cross section and hydraulic roughness characteristics.
