【摘要】 近年来,水文行业开始引进ADCP(声学多普勒流速剖面仪)应用于流量测验中。通过ADCP测流技术在三角洲河口区潮流量测验的实际应用与常规仪器的比较,分析各种数据误差的来源及合理性,特别是在潮流区测验中与常用仪器的表面误差分析,说明其误差是河流水体运动的真实反映。得出ADCP测流法可以在三角洲网河区使用,特别是在珠江三角洲网河地区更应该大力推广该项技术,加快实现水文水利现代化的步伐。更多还原

【Abstract】 In recent years,ADCP has been introd uced in hydrology operation for flow measurement.From the comparative measurement with tradi tional instruments for tidal flow in delta estuary,the article analyses the causes and rationality of data errors.Especially the analysis on reasonable decision making on errors reveals that show the pulsating flow facts.Thus ADCP is re cognized to be feasible in delta area,and should be extended in Pearl River Delta areas in order to update hydrological and water resources moderniz ation.更多还原
