Analysis of Velocity Coefficient of Water Surface of Mountain Stream Rivers
Babao river is a typical mountain stream river,and it is difficult to measure velocity using the multi-point method.By analyzing the velocity of the measuring points at the relative water depth positions of 0.0 and 0.6 of the velocity vertical line of the flow test section of the Qilian hydrological station(hereinafter referred to as the Qilian Station)of the Babao river water control station,the test value range of the water surface velocity coefficient was calculated,and the test coefficient of the one-point method semi-empirical formula was derived.The water surface velocity formula was qualitatively determined using the actual test data,so as to be applied to the flow test of the rotor current meter and radar wave current meter at the hydrological station.
