摘要
本文建立了一无分叉灌溉渠道系统非恒定流计算机模拟模型。渠道断面可以是规则的或不规则的；横向水工建筑物可以是水闸、堰，侧向水工建筑物可以是水闸、堰、水泵站，且可任意组合．该模型可用作渠道系统的设计，运行管理，自动化中水力计算的工具。
Based on the numerical solution of complete Saint Venant Equations,anunsteady flow simulation model for non-branched canal system was developed in thispaper. The main features of the model include: 1). The cross section can be regular orirregular. 2). The cross structures can be sluice gate, weir or drop. 3 )' The of ftakestructures can be sluice gate, weir or pumping plant. 4). The operation of structures isdescribed in time series. The model can be used as a hydraulic computation tool forcanal design,system operation and canal automation.
