雷达测速仪水文测验的应用研究

Studies on application of radar current meter for hydrological test

以不同特性河流的水文站对雷达测速仪与转子流速仪进行对比试验研究,发现在许多河流都能用雷达测速仪施测水面流速。结果表明,两者具有良好的相关关系。对水面流速系数或流量系数率定后,得出断面流量精度较浮标施测的高,安全可靠,能节约大量人力物力,并有利于今后自动化遥测站的发展。

Comparative experiments of radar current meter with roter current meter were made for hydrological stations under different river regimes. It is found that flow velocity of water surface can be measured by radar current meter in many rivers since the two has a good correlation and the precision of section flow tends to be higher than that measured by float gauging after calibration of coefficient of flow velocity or flow coefficient. Radar current meter, as a safe and reliable tool, has a great potential for wider application and can save manpower and material resources and can also be used in computer-controlled telemetric station in the future.
