《河流流量测验规范》有关水位级划分理论的商榷

《河流流量测验规范》第六章高洪流量测验中提出的有关水位级划分的方法，对水量丰沛的南方大河干流的计算结果相差较小，而对来水丰枯悬殊的支流小河、有水利工程影响及黄河以北季节性结冰河流，其计算结果相差甚远。作为国家标准，应该适用于国内各种河流，不宜相差甚远。本文提出了黄金分割法（或优选法）及经验法计算各站水位级，比较合理，适合各种情况的河流。推荐使用黄金分割法。

Discussion about the Theory of Water Level Partition in River Discharge Measurement Criterion

Methods used for partitioning water level proposed in chapter VI, High Flood Flow Tests, of River Di~harge Measurement Standards, cause small difference in calculaing the main stream with abundant water in the .south, while the calculated results are quite different for branch rivers with apparent abundance or shortage of river water and affected by water conservancy projects ,as well as the seasonal iced fiver in the north of the Yellow River. As the national standard, it should be applied to all rivers. Gold section methods （ or prefered method ） and empirical method, which are more reasonable in calculating water level at all stations, suit for a variety of fiver conditions. Gold section method is recommended.
