标准棱柱体明渠中的测水量水方法

Water Measurement Method in Standard Prism Open Channel

通过对三面采用混凝土护砌的标准棱柱体明渠实测资料的分析,建立水深糙率曲线,并根据建立的水深糙率曲线计算灌溉水量,并对计算精度进行了分析。有了糙率曲线数学模型,计算灌溉流量或水量时,可减少工程技术人员的劳动强度,同时也为灌区调水配水和节水灌溉提供了科学依据。

Through analysis on measured data by standard prism open channel applying three-side concrete protection engineering, depth-roughness curve is plotted, based on which irrigation amount can be calculated, and analysis on calculation precision is also made. Calculation of irrigation discharge or water amount by depth-roughness curve mathematical model can reduce technical personnel labor intensity, and provide scientific evidences for water transfer, water distribution in irrigation area and water-saving irrigation as well.
