摘要
为提高荆江河段沙市(二郎矶)站水位流量关系精度,利用沙市(二郎矶)站2015~2020年水位、实测流量资料以及辅助水尺断面水位资料,对现有落差指数法中的参数进行分析优选,优化校正流量计算公式。结果表明:使用优化后的参数计算的沙市(二郎矶)站水位校正流量关系点更为集中,定线更为简洁,且精度可靠,满足国家相关规范要求。研究成果可为减少流量测次、提高测验效率、简化水文资料整编工作提供参考。
In order to improve the accuracy of-discharge relationship at Shashi(Erlangji)Hydrological Station in Jingjiang River reach,this paper optimized the parameters in the existing drop index method and corrected the calculation formula of discharge on the basis of observing data of water level and discharge,measured water level data of staff gauge cross-sectionof Shashi(Erlangji)Hydrological Station from 2015 to 2020.The results showed that after optimizing parameters,points of water level-adjusting factor relation were more concentrated,and line segment was more concise.Accuracy of the results were improved,which could meet the requirements of relevant national standards.The research results can provide reference for reducing flow measurements,improving test efficiency and simplifying the compilation of hydrological data.
