黄河下游（北洛河水系）逐年各时段洪水量统计数据（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各时段洪水量特征值统计资料，人工数字化获得。

This dataset contains two parts of hydrological statistics: 1) Annual flood discharge statistics for each time period at main stream water level stations in the lower-middle reaches of the Yellow River (from Longmen to Sanmenxia Reservoir), which were digitized and organized based on the original document *Statistics of Hydrological Characteristic Values of the Yellow River Basin (1919–1970)*; 2) Statistical data of flood discharge characteristic values for each annual time period at main stream hydrological stations in the downstream region of the Yellow River Basin (Beiluo River system) covering the period 1919–1970, which were collected and obtained via manual digitization.
