|
Abstract:
2020年8月，长江上游发生大洪水过程。介绍寸滩站洪水测验主要方法及情况，并从水位流量关系分析、上下游对照、水量平衡三方面分析测验成果合理性和可靠性，结果表明：测验布置合理，水位流量关系符合测站特性，洪水测验成果总体可靠。
A major flood occurred in August 2020 in the upper reaches of the Yangtze River. The paper introduced the main hydrological measurement methods and conditions, the relationship between water level and flood discharge at the Cuntan station. The rationality and reliability of the relationship between water level and discharge, the comparison of upstream and downstream, and the water balance were analyzed. The results show that the hydrological measurement layout is reasonable, the relationship between water level and discharge conforms to the station characteristics, and the flood measurement results are generally reliable.
