中文摘要:
      2017年7月,西江中下游高要水文站发生2008年以来最大洪水,洪峰流量为43 500 m3/s,洪水流量量级接近20年一遇。对比以往高要水文站洪水水位流量逆绳套关系,本场洪水水位流量呈单一线性关系。该文从水位、流量测验合理性,关系曲线三项检验,洪水过程对比分析,阐述本场洪水水位流量单一线性关系的合理性,为西江洪水预报与防汛工作提供依据。
英文摘要:
      In July 2017, Gaoyao Hydrological Station at lower Xijiang River witnessed the most serious flood since 2008, with a peak flow of 43500m3/s and nearly 20-year return level. In contrast with the usual anticlockwise loop curve, the stage-discharge relation of this flood is sole linear. The rationality of the stage-discharge relation of this flood in terms of stage and discharge measure rationality, stage-discharge curve examination and flood process contrast are analyzed, offering support for flood prediction and prevention in the Xijiang River Basin.
