The data set contains the observation data of river water level and velocity at point 3 in the intensive observation of runoff in the middle reaches of Heihe River from June 13 to November 24, 2012. The observation point is located at Heihe bridge of Lanxin railway in Zhangye City, Gansu Province, with a river width of 50m. The riverbed is sandy gravel with stable section. The longitude and latitude of the observation point are n39 ° 2'33.08 ", E100 ° 25'49.42", 1443m. Sr50 ultrasonic rangefinder is used for water level observation, and the acquisition frequency is 30 minutes; Streampro micro ADCP is used for profile flow observation. The data description includes the following parts:
Water level observation: sr50 ultrasonic rangefinder is used. The data covers the time period from June 14 to November 24. The observation frequency is 30 minutes, unit (CM);
Flow observation: the flow is monitored by ADCP through the latest technical means to obtain accurate water level flow curve, and the runoff change process is obtained by relying on water level process observation. Unit (M3 s-1);
The missing value data is uniformly represented by string - 6999.
