摘要
作者通过圣维南方程组的有限差分数值解并使用比例控制方式，编写出计算机程序，实现了自动上游控制灌溉渠道系统的计算机模拟。该程序也可用于人工上游控制灌溉渠道系统，能够根据取水建筑物的流量需求确定控制建筑物的调节。在上游控制渠道系统调控方法的研究中该程序可用作检验调控方法的工具。本文介绍了该计算机程序的主要算法。
Based on the numerical solution of Saint Venant Equations and proportional control mode,the author established a computer program for simulating automatic upstream control irrigation canal system .It can also be applied to manual upstream control irrgation canal system to determine the adjustment of control hydraulic structures from the water demand of offtake hydraulic structures.In developing control algorithm for upstream control irrigation canal system ,it can be used as a tool for testing the control algorithm.The main theoretical background is presented in this paper.
