受洪水冲於影响水位流量关系曲线分析

Analysis on Water Level and Discharge Relationship Curve Affected by Flood

以永翠河带岭站为例,提出了受突发洪水冲淤影响的测流断面在进行水文测验和资料整编工作中应采取的具体方法和实用措施。分别从水位观测时段控制,流量测次布置原则,水位～流量关系曲线定线技巧和曲线精度检验等几个方面进行了具体论述,为提高受非经常性冲淤影响水文断面的流量测验和整编工作质量提供了一些方法和建议。

Taking Daling Hydrological Station at Yongcui River as an example,concrete method and practical measures for the gauging section and data compilation affected by a sudden flood are brought forward. It is discussed concretely referring to water level observation period control ,layout principle of flow measurement, aligmnent techniques of water level and discharge relationship curve, and curve precision inspection respectively. It provides some methods and suggestions for heightening data compilation quality of the hydrological cross-section discharge affected by non-recurring flood.
