该数据集包含了2014年7月28日至2014年12月31日的黑河中游径流加密观测中3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兰新铁路黑河桥，河床为砂砾石，断面稳定。观测点的经纬度是N39°2'33.08\"，E100°25'49.42\"，1443米，河道宽度50米。水位观测采用SR50超声测距仪，采集频率60分钟；剖面流量观测采用StreamPro微型ADCP。数据说明包括以下部分：
\n水位观测，观测频率60分钟，单位（cm）；数据涵盖时间段2014年7月28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。
