摘要：为缩短测验历时及抢测洪峰、增加测验安全，宜昌水文站引进了电波流速仪测流，为了保证电波流速仪在该站的测验精度，使测验资料可靠性有所保证，本站进行了电波流速仪系数的对比试验，并进行了分析，得出一些结论，这样以来大大提升报汛质量和时效性，从根本上解决了受工程影响测站流量测报的难题，提升了超高洪水下水文测验人员的安全性，同时也将水文信息化向水文智能化发展提升了一个高度。

Abstract: Abstract: In order to shorten the duration of the test, rush to measure the flood peak and increase the safety of the test, Yichang Hydrological Station introduced the surface velocity radar to measure the flow. In order to ensure the test accuracy of the surface velocity radar at the station and ensure the reliability of the test data, the station conducted a comparative test of the surface velocity rada coefficients, analyzed them, and drew some conclusions, which greatly improved the quality and timeliness of flood reporting, It fundamentally solved the problem of flow measurement and reporting at the measuring station affected by the project, improved the safety of hydrologic testers under ultra-high flood, and also promoted the development of hydrological information to a higher level of hydrological intelligence.
