摘要
The variable-parameter simplified stage-hydrograph routing method developed in Part I of this series is studied to determine its limitations, the criterion for its applicability, and its accuracy based on the assumptions used for its development. This method is evaluated by routing given hypothetical input-stage hydrographs through uniform rectangular cross-section channels and comparing the results with the corresponding numerical solutions of the Saint Venant equations. The discharge hydrographs as computed by the method are also compared with the corresponding Saint Venant solutions. The method closely reproduces the stage and discharge hydrographs obtained from the Saint Venant solutions subject to compliance with the assumptions of the method.
