The data set contains the observation data of river water level and velocity at point 6 in the intensive observation of runoff in the middle reaches of Heihe River from August 10, 2012 to December 31, 2013, in which the water level gauge was lost from April 5 to September 6, 2013. The observation point is located at zhaojiatunzhuang Gaoya National Hydrological Station, Ganzhou District, Zhangye City, Gansu Province. The riverbed is sandy gravel and the section is stable. The longitude and latitude of the observation point are n39 ° 08'06.35 ", E100 ° 25'58.23", 1420m above sea level and 50m wide.
The data set contains the observation data of river water level and velocity at point 8 in the intensive observation of runoff in the middle reaches of Heihe River from June 17, 2012 to December 31, 2013. The observation point is located at Heihe bridge, Gaotai County, Zhangye City, Gansu Province. The riverbed is sediment and the section is stable. The longitude and latitude of the observation point are n39 ° 23'22.93 ", n 99 ° 49'37.29", with an altitude of 1347m and a river width of 210m.
The observation point is located at Heihe bridge, 312 national highway, Zhangye City, Gansu Province. The riverbed is sandy gravel and the section is unstable. The longitude and latitude of the observation point are N38 ° 59 ′ 51.71 ″, E100 ° 24 ′ 38.76 ″, 1485m above sea level, 70m and 20m wide. Sr50 ultrasonic rangefinder is used for water level observation, and the acquisition frequency is 30 minutes
The data description includes the following parts:
Water level observation, observation frequency 30 minutes, unit (CM); The data covers the period from January 1, 2014 to December 31, 2014
Flow observation, unit (M3); Monitor the flow according to different water levels, obtain the water level flow curve, and obtain the runoff change process based on the water level process observation
The section of No. 2 point - 312 bridge was frequently disturbed artificially, the area of hydrological section was unstable, resulting in the disorder of water level and discharge curve, and the stable flow and water level curve was not obtained during the measurement. The missing value data is uniformly represented by string - 6999
