1.   Purpose and objectives

     Flood routing by the Muskingum method. This component takes into account the change of velocity due to discharge, and the method is reformulated as a non-linear problem which is solved using a computer program.

2.   Description

     The inflow hydrograph is known and the outflow discharge is to be obtained. Four parameters are introduced to define how the values of  Muskingum's K and x are related to discharge. All these parameters can be determined from the hydraulic properties of the channel.

3.   Input

     Inflow and outflow hydrographs of the channel.

4.   Output
        
     Numerical table of the inflow and outflow hydrographs. Plot of computed and measured hydrographs of outflow.

5.   Operational requirements and restrictions

     The user should be familiar with the basic theory of the method.

6.   Form of presentation

     Manual in English, printed listing of program and floppy diskette.

7.   Operational experience

     It has been applied successfully in different river reaches in China.

8.   Originator and technical support

     Zhao Ren-jun and Wang Pei-len, Hohai University, Nanjing, China
