该数据集包含了2014年1月1日至4月30日，2014年7月18日至2014年7月26日的黑河中游径流加密观测中5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临泽县板桥乡黑河桥，河床为砂砾石，断面不稳定。观测点的经纬度是N39°15'32.41\"，E100°16'33.95\"，海拔1398米，河道宽度270米。2014年水位观测采用SR50超声波测距仪观测，采集频率30分钟，观测期间仪器故障返厂维修，后期安装后故障并未排除。数据说明包括以下两部分：
\n水位观测，观测频率30分钟，单位（cm）；数据涵盖时间段2014年1月1日至2014年4月30日，2014年7月18日至2014年7月26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。

The observation point is located in Heihe Bridge, Banqiao Township, Linze County, Zhangye City, Gansu Province. The riverbed is composed of sand and gravel, and the cross-section is unstable. The latitude and longitude of the observation point are N39 ° 15'32.41 \", E100 ° 16'33.95\", with an altitude of 1398 meters and a river width of 270 meters. In 2014, the water level was observed using an SR50 ultrasonic rangefinder, with a collection frequency of 30 minutes. During the observation period, the instrument malfunctioned and was returned to the factory for repair. After installation, the problem was not resolved.
