该数据集包含了2012年6月13日至2013年9月6日的黑河水文气象观测网中游径流加密观测中1号点的河流水位观测数据。
\n观测点位于甘肃省张掖市213省道黑河桥，分为两个河道，河床为砂砾石，断面不稳定。观测点的经纬度是N38°54'43.55\"，E100°20'41.05\"，海拔1546米，河道宽度330米。213桥分为两个断面，东面的为1号，西面的为2号。由于河道断面人为影响频繁无法获取稳定的水位流量曲线于2013年9月6日停止观测。
\n水位观测采用SR50超声测距仪，采集频率30分钟。数据说明包括以下部分：\n
\n水位的观测频率30分钟，单位cm；数据涵盖时间段2012年6月13日-2013年9月6日；
\n流量观测，单位（m3 s-1）；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。1号点-213桥断面受到频繁人为扰动，水文断面面积不稳定导致水位流量曲线紊乱，流量数据有待进一步观测。缺值数据统一采用字符串-6999表示。
