摘要
近年来随着水文信息化建设成效日益显著,宁夏部分水文站安装使用双轨式雷达波自动在线监测系统(以下简称“双轨式流速仪”),双轨式流速仪有着安全可靠、省时省力、测速快、全天候工作等优点。此次通过对泉眼山水文站双轨式流速仪与LS10型、LS25-1型流速仪、电波流速仪进行比测分析,率定水面系数,为大规模推广使用提供数据支撑。
In recent years,with the increasingly remarkable achievements of hydrological informationization construction,some hydrological stations in Ningxia have installed dual-track radar wave automatic velocimeter(hereinafter referred to as"dual-track velocimeter"),which has the advantages of safety,reliability,time-saving and labor-saving,fast speed measurement and all-weather work.By comparing and analyzing the two-track velocity meter with LS10,LS25-1 and radio-wave velocity meter at Quanyanshan Hydrological Station,the water surface coefficient is calibrated to provide data support for large-scale popularization.
