都安水文站水平式ADCP流速关系率定分析

Velocity relationship calibration analysis of horizontal ADCP for Duan Hydrological Station

水平式ADCP技术应用的关键是指标流速与断面平均流速关系的率定。以都安水文站的应用情况为例,论述了指标流速与断面平均流速关系率定的实质与内容,以水平式ADCP监测指标流速,以常规流速仪测定断面平均流速,在收集一定资料成果后,率定出最佳相关方程,为都安水文站及类似水文站开展水平式ADCP在线流量监测、资料整编等提供经验和技术依据。

Calibration of index velocity and cross-sectional average velocity relationship is the key for technical application of horizontal ADCP.Taking the application at Duan Hydrological Station as example,the author discussed the essential and content of calibration.Index velocity was measured with horizontal ADCP while cross-sectional average velocity was measured with conventional current meter.The optimum correlation equation was calibrated based on certain measuring data documents,which provide experience and technical support for Duan Hydrological Station and other similar stations to adopt horizontal ADCP on-line flow monitoring and organize documents.
