Lateral Distribution of Average Vertical flow Velocity and Its Application in Open Channel

HAN Jin-xu1,LI Jing-ru2,DU Kai 1,CAI Da-ying1,LI Zhao-yue1(1.Yellow River Institute of Hydraulic Research,Zhengzhou 450003,China;2.Yellow River Engineering Consulting Co.,Ltd.Zhengzhou 450003,China)  
Based on indoor and field experiments,velocity distribution properties of open channel were analyzed,the parabolic law for lateral distribution of average vertical flow velocity was established in open channel,and the method for flow measurement in open channel was put forward based on the parabolic law.The results showed that apart from a few point,the fractional errors between measured velocities and calculated velocities by the parabolic law were smaller than±5% when(1-2x/B)0.1.In addition,the method for flow measurement was adapt to different forms of channels with high accuracy.
