摘要
通过对WR-2000型自计式水位计系统在张掖大满灌区不同渠道断面上的实际应用,对该系统的精度、应用环境和范围进行了研究.结果表明,该系统比传统的人工观测精度高、效率高,在支、斗渠上可大面积推广应用,节省大量人力.
WR-2000 hydrograph system newly developed by Beijing Water Conservancy Academy and Gansu Water Conservancy Institute was applied to irrigation water monitoring in different sections of ditchs in the Daman irrigation area in Zhangye City of Gansu Province in order to detect its measure precision, application setting and range. The results showed that the system had higher measuring precision and efficiency comparing with artificial observation method, and could be extensively applied to automatic water management of irrigation area.
