摘  要:以湖南省桃江水文站为研究对象,提出声学多普勒流速剖面仪(ADCP)垂线平均流速计算模型,通过对比分析表明ADCP施测的流速与转子速仪施测的垂线平均流速存在很好的一致性。因此该模型具有较好的适用性及推广应用价值,为水文缆道自动测流系统的建设提供技术支撑。Taking the Taojiang hydrological station in Hunan Province as the research object, a calculation model of the vertical average velocity of the acoustic Doppler velocity profiler was proposed. The comparative analysis shows that the velocity measured by the acoustic Doppler velocity profiler and the average vertical velocity measured by the rotor velocity profiler are basically the same. Therefore, the model has good applicability and promotion value, and provides technical support for the construction of the hydrological cableway automatic flow measurement system.
