Problems solved by technology

[0002] At present, the common method of measuring the flow velocity of the river is the use of ADCP (Acoustic Doppler Current Profilers, Acoustic Doppler Current Profilers) measurement, which can be divided into navigation type or fixed type, that is, the use of ADCP flow velocity measurement principle The vertical line in the watershed section is different The flow velocity at the point level and the average flow velocity on different vertical lines are used to calculate the overall river flow according to the flow velocity at multiple points in the section. This kind of equipment is expensive. When using it for surveying, it needs to be calibrated and debugged to input a variety of measurement parameters, which is labor-intensive. material resources
