一种推求设计洪水过程线的新方法

针对水利工程设计中用分时段同频率放大法推求设计洪水的不足,提出一种通过解线性方程组推求设计洪水过程线的简便方法。该方法运算过程简单,直接利用Excel的内置函数求解,又能避免徒手修匀洪水过程线的任意性。文中给出了一个计算实例。

A New Method for Calculating Design Flood Hydrograph

To overcome the shortages of the method that enlarges the model hydrograph by keeping the peak discharge and flood volume of different duration in the same frequency,this paper gives a method for calculating design flood hydrograph through solving a system of linear equations.This method reduced the arbitrariness caused by man-made work.An applied example is also given in this paper.
