Optimization of Operation of An Aqueduct System Under Drought and On-Demand Delivery

9312735耶这个美国-巴西联合项目的目的是研究正在建设中的、位于巴西东北部“干旱多边形”内的卡拉巴斯灌溉项目。正在安装一个可以在开环或闭环模式下运行的自动闸门控制系统，以及用于发出水位和闸流需求变化和波动信号的传感器。该系统的数据将用于验证和开发自动控制方法以及与为干旱和半干旱地区设计的按需灌溉、供水和渡槽系统兼容的各种运行模式。***

9312735 Yeh The purpose of this United States-Brazil joint project is to study the Caraibas irrigation project which is under construction and located within the "drought polygon" of the Northeastern region of Brazil. An automated gate control system that can function in an open or close loop mode, and sensors for signaling demand changes and fluctuations in water levels and gateflows are being installed. Data from this systems will be used to validate and develop automatic control methods as well as various modes of operation compatible with on-demand irrigation water delivery and aqueduct systems designed for arid and semi-arid regions. ***
