该数据集包含了2012年6月17日至11月24日的黑河中游径流加密观测中8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高台县黑河桥，河道宽度210米。河床为泥沙，断面稳定。观测点的经纬度是N39°23'22.93\"，N 99°49'37.29\"，海拔1347米。数据说明包括以下两部分：\n
\n水位观测：采用SR50超声测距仪，数据涵盖时间段6月17日至11月24日，观测频率30分钟，单位（cm）；\n
\n流量观测：通过最新技术手段ADCP监测流量，获取精确的水位流量曲线，依托水位过程观测获得径流量变化过程。单位（m3 s-1）；\n
\n缺值数据统一采用字符串-6999表示。\n
\n多尺度观测试验或站点信息请参考Liu et al. (2016)，观测数据处理请参考He et al.(2016)。
