1. 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 July 28, 2014 to December 31, 2014
2. 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 January 1, 2014 to December 31, 2014
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 observation point is located at Heihe bridge of Lanxin railway in Zhangye City, Gansu Province. The riverbed is sandy gravel and the section is stable. The longitude and latitude of the observation point are n39 ° 2'33.08 ", E100 ° 25'49.42", 1443m, and the river width is 50m. Sr50 ultrasonic rangefinder is used for water level observation, and the acquisition frequency is 60 minutes; Streampro micro ADCP is used for profile flow observation
The data description includes the following two parts:
Water level observation, observation frequency 60 minutes, unit (CM); The data covers the period from July 28, 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 missing value data is uniformly represented by string - 6999
Good data quality
