岭景水文站水位流量关系单值化分析

Single-value analysis of water level-discharge relationship for Lingjing Hydrological Station

实现水位流量关系单值化是新形势下进一步减少水文站点人力投入,推进测验方式改革,提高工作效率,增强水文服务能力的必要过程。对于测验环境复杂的中小河流站点,通过分析水位流量关系单值化关系,可以精简测验方式,减轻洪水期间测验工作量,更好地实现小机构大服务。本文利用岭景水文站近5年来的实测资料对水位流量关系进行分析,结果表明历年水位流量关系线在43.65~48.10m之间的定线误差符合规范要求,可以使用综合关系线推流。

Realizing the single valued water level-discharge relationship is a necessary process to further reduce manpower input in hydrological stations,promote the reform of measuring mode,improve work efficiency,and en⁃hance hydrological service capabilities under the new situation.For those stations on mid-and small rivers with complex measuring environment,though single-value analysis of the water level-discharge relationship,the measur⁃ing mode can be simplified and the measuring workload be reduced,so as to better realize small organization provid⁃ing large service.For Lingjing Hydrological Station,the water level-discharge relationship was analyzed based on the measurement data in the last 5 years.The results of analysis demonstrate the alignment error of the water leveldischarge relationship curve over the years with the level variable within 43.65m~48.10m meets the requirements of specification,and the discharge can be calculated by use of the comprehensive relationship curve.
