官厅水库八号桥水文站典型年水位流量曲线分析

Analysis of water level and flow curve of Guanting Reservoir No.8 Bridge Hydrological Station in typical year

为了更加准确地确定官厅水库八号桥水文站定线方法,使流量数据更加可靠,研究了以2021年为典型年的官厅八号桥水文站水位流量关系曲线的变化规律,运用了SL/T 247—2020中《水文资料整编规范》单一线、连实测过程线等定线和检验方法,分析了官厅水库八号桥水文站2021年实测流量数据的定线过程。结果表明:畅流期实测流量适宜选用单一线法定线,冰冻期适合采用连实测过程线法定线。通过不同时期选用合适的水文定线方法,提升了定线的合理性,对水情报讯、水文应急服务以及水文资料整编工作具有重要意义。

In order to more accurately determine the alignment method of the Guanting Reservoir No.8 Bridge Hydrological Station and make the flow data more reliable,the variation law of the water level flow relationship curve of the Guanting Reservoir No.8 Bridge Hydrological Station in 2021 was studied.The alignment and inspection methods of single line and continuous measured process lines in the"Hydrologi-cal Data Compilation Specification"SL/T 247-2020 were used to analyze the alignment process of the measured flow data of the Guanting Reservoir No.8 Bridge Hydrological Station in 2021.The results indi-cate that during the smooth flow period,a single line is suitable for measuring flow rate,and during the freezing period,a continuous measurement process line is suitable for measuring flow rate.By selecting appropriate hydrological routing methods at different stages,Significantly improved the rationality of the alignment.which is of great significance for meeting the needs of water situation reporting,hydrological emergency services,and hydrological data compilation work.
