AB  - The data set contains the observation data of river water level and velocity at point 2 in the intensive observation of runoff in the middle reaches of Heihe River from June 19 to November 24, 2012. The observation point is located at Heihe bridge, 312 National Road, Zhangye City, Gansu Province. It is divided into two rivers. The East is marked as No. 1 and the west is marked as No. 2. The river width is 70m and 20m respectively. The riverbed is sandy gravel and the section is unstable. The longitude and latitude of the observation points are N38 ° 59 ′ 51.71 ″, E100 ° 24 ′ 38.76 ″, with an altitude of 1485m. The data description includes the following parts:Water level observation: sr50 ultrasonic rangefinder is used. The data covers the time period from June 19 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. The section of No. 2 point - 312 bridge is subject to frequent artificial disturbance, and the water level discharge curve needs further observation, unit (M3 s-1);The missing value data is uniformly represented by string - 6999. For multi-scale observation test or site information, please refer to Liu et al. (2016), and for observation data processing, please refer to he et al. (2016)
