三湖河口水文站位于内蒙古自治区乌拉特前旗公庙子镇三湖村，地理坐标为东径108°46′27″，北纬40°36′19″，是国家基本水文站和重要水文站，是国家重点报汛站，是黄河干流重要控制站。观测项目有水位、流量、含沙量、大断面、水温、冰情等。本数据集为三湖河口站1960-2018年历年大断面及水位、流量观测数据，经曼宁公式计算及实测资料分析得到该站历年平滩水位对应的流量。本数据集共包含1 个excel文件，共两列，1列为年份，1列为年平滩流量。", "ds_source": "
该数据集数据全部为水文站观测数据经分析计算后的数据，水文站大断面及水位、流量资料严格按照国家水文站观测规范要求进行观测，流量测验设备主要有走航式相控阵ADCP、SSZ超声波测深仪、手持GPS平板定位仪、智能流速记录仪、流向仪、流速仪、测深杆等。源数据日流量资料来源于每年刊印的水文年鉴，购买自黄河水利委员会水文局。", "ds_process_way": "
平滩流量是某一河段平滩水位时对应的流量。其计算方法：（1）利用曼宁公式推求水文站断面水位流量关系，从而得到平滩水位对应的流量；（2）利用水文站实测水位、流量资料绘制断面实测水位流量关系；两种方法经综合对比分析确定该站某一年份的平滩流量。", "ds_quality": "

Sanhuhekou hydrological station is located in Sanhu village, gongmiaozi Town, wulatqian banner, Inner Mongolia Autonomous Region. Its geographical coordinates are 108 ° 46 ′ 27 \"East diameter and 40 ° 36 ′ 19\" north latitude. It is a national basic hydrological station and an important hydrological station, a national key flood reporting station, and an important control station of the main stream of the Yellow River. Observation items include water level, flow, sediment concentration, large section, water temperature, ice condition, etc. This data set is the observation data of large section, water level and flow of sanhuhekou station from 1960 to 2018. The flow corresponding to the flat water level of the station over the years is obtained through Manning formula calculation and measured data analysis. This data set contains an excel file with two columns, one is the year and the other is the annual flat discharge.
