Description

River channel flow measurement is an important work for regional hydrological management, and the monitoring content of the river channel flow measurement comprises the water depth, the flow speed and the flow of the river channel. An Acoustic Doppler flow Profiler (ADCP) is a water Acoustic flow meter for measuring water velocity. The principle is similar to sonar: ADCP emits sound waves into water, and scatterers in the water scatter the sound waves; the ADCP receives the echo signal returned from the scatterer, and calculates the flow velocity by analyzing the doppler shift.

When river channel flow measurement is carried out, an ADCP with a bottom tracking function and a carrier capable of carrying the ADCP (similar to a ship board type) to carry out water area crossing are needed. Crossing from one bank to the other, estimating the cross-sectional area of the motion trajectory of the carrier to the water bottom from the depth and velocity data; and performing dot product on the vector locus and the flow velocity, and calculating to obtain the flow. Compared with the traditional method for calculating the flow measurement by the depth measuring rod and the single-point current meter, the method has the advantages that: the point integral calculation does not require the running route of the moving carrier to be a straight line, and the curve broken line can be used; the data accuracy is greatly improved by the ADCP layered measurement principle; time and labor are saved, and the like.

While there are many advantages to using ADCP side-streaming, there are also drawbacks. For example, when a plurality of measuring points are arranged in a river channel along a direction perpendicular to the water flow direction, the ADCP needs to be moved transversely, and the friction between a sling suspending the ADCP and a guide rope is large during movement, so that the ADCP instrument swings leftwards and rightwards greatly, the stability of measurement is not facilitated, and the measurement needs to be performed after the device is stable, which takes time.
