灌溉渠道流量调控模型

A Regulation Model for Flow in Irrigation Canal Systems

本文根据Ｓａｉｎｔ－Ｖｅｎａｎｔ方程和闸孔出流方程建立了一个比较简单的渠道流量调控模型，可以预报配水方案下整个渠系的运行状态和闸门调节过程，并可选择系统最佳运行方案，对渠系用水管理和工程管理有很大帮助。文中还讨论了建模过程中应考虑的一些问题及处理方法，通过实例验证，得到了令人满意的结果。

Based on the Saint-Venant equations and the sluice discharge equation,a simple regulation model for flow in irrigation canal systems is developed to predict the operational status of the canal systems and the regulation procedures of the sluice gates for given water distribution strategies, and to select the optimum operation for canal systems to avail the management of agricultural water and projects. In addition,some problems resulted from model building and their solutions are discussed. Results obtained from field test proves that the model is satisfactory.
