黑河生态水文遥感试验：水文气象观测网数据集（6号点-高崖水文站径流观测数据-2014）

该数据集包含了2014年1月1日至2014年12月31日的黑河中游径流加密观测中6号点的河流水位和流速观测数据。观测点位于甘肃省张掖市甘州区赵家屯庄高崖国家水文站，河床为砂砾石，断面稳定。观测点的经纬度是N39°08'06.35"，E100°25'58.23"，海拔1420米，河道宽度50米。水位观测采用HOBO压力水位计，采集频率60分钟。数据说明包括以下两部分：
水位观测，2014年为60分钟，单位（cm）；数据涵盖时间段2014年1月1日至2014年12月31日；流量观测，单位（m3）；按照不同水位监测流量，获取水位流量曲线，依托水位过程观测获得径流量变化过程。缺值数据统一采用字符串-6999表示。

This dataset contains river water level and flow velocity observation data from Station No. 6 in the intensive runoff observation campaigns in the middle reaches of the Heihe River, covering the period from January 1, 2014 to December 31, 2014. The observation station is located at the Gaoya National Hydrological Station, Zhaotunzhuang, Ganzhou District, Zhangye City, Gansu Province. The riverbed is composed of gravel and the cross-section is stable. The geographic coordinates of the station are N39°08'06.35", E100°25'58.23", with an altitude of 1420 meters and a river channel width of 50 meters. Water level observations were conducted using a HOBO pressure-type water level logger, with a sampling frequency of 60 minutes.

The data descriptions include two parts:
1. Water level observations: the sampling interval in 2014 was 60 minutes, with the unit of centimeter (cm); the data covers the period from January 1, 2014 to December 31, 2014.
2. Flow observations: the unit is cubic meter (m3); flow was monitored at different water levels to establish the stage-discharge curve, and the runoff variation process was derived from the observed water level time series. Missing values are uniformly represented by the string -6999.
