黄河下游（北洛河水系）逐年水位频率（最高水位）数据（1919-1970年）

根据《1919-1970黄河流域水文特征值统计》白本数字化整理出黄河中游下段（龙门至三门峡水库）黄河干流水位站点逐年各时段洪水量统计数据，收集整理1919-1970年黄河流域下游区（北洛河水系）黄河干流水文站点逐年枯水流量特征值统计资料，人工数字化获得。

This dataset includes two sets of statistical data. The first set comprises annual flood discharge data for each time interval at main stream water level gauging stations in the lower-middle reaches of the Yellow River (from Longmen to the Sanmenxia Reservoir), which was digitized and organized based on the raw original edition of *Statistics of Hydrological Characteristic Values of the Yellow River Basin (1919–1970)*. The second set consists of annual low flow characteristic value data at main stream hydrological gauging stations in the lower reaches of the Yellow River Basin (including the Beiluo River system) from 1919 to 1970, which was collected, sorted out and obtained through manual digitization.
