摘要
在对某水库库区河道进行一维明渠非恒定流计算的基础上 ,给出了在这种库区河道选取糙率的方法 ,并对计算中所使用的糙率特性进行了探讨 .其糙率特性分析表明 。
A method for selecting roughness of reservoir's river course is presented based on one_dimensional unsteady flow computation in open channels. And roughness characteristics using for computation are discussed. It is shown that the roughness of reservoir's river course is different from ones of natural river courses.
