%X This data set is the river flow observation data of hulugou small watershed in the upper reaches of Heihe River Basin from July to September 2012. The solinst levellogger automatic water level gauge is used to observe the water level of the river, and the flow data is calculated through the water level discharge curve. The actual flow observation is manual observation through the self-made flow weir (see the thumbnail). Due to the limited amount of manual observation data, it is necessary to further supplement the observation and improve the water level discharge curve.Point 01: the exit of area III divided by Institute of cold and drought, Chinese Academy of Sciences, and the dividing point of cold desert zone and cold Dian zone. The gully is deep and bedrock is exposed. Coordinate (99 ° 53 ′ 37 ″ e, 38 ° 13 ′ 34 ″ n) observation period: June 28, 2012 to September 2, 2012. The observation frequency of automatic observation data is 6.28-7.25, once per 30 minutes. 7.25-9.2 is 1 time / 15 minutes. Point 02: the exit of area II, which is divided by Institute of cold and drought, Chinese Academy of Sciences, is located at the confluence of the outlet of alluvial delta Valley, and the shrub area is on the south side. There is a small flow weir. The observation frequency of automatic observation data of observation point coordinates (99 ° 52 ′ 58 ″ e, 38 ° 14 ′ 36 ″ n) is 1 time / 15 minutes.
