本文提出了一些复杂的问题，与方法和初步分析的速度和流量测量使用各种技术应用于英国黑水河。ADCP的部署程序进行了调整，以考虑到在小河流中使用这种设备的困难。采用ADCP和ADV测量了主槽中部的流速剖面，并分别在800 s和300 s的时间尺度上取平均值，以获得稳定值。在两次测量之间的平均流向速度中观察到约6.8%的差异。一个很好的协议之间的表面速度测量PIV和ADCP的横截面位于直和蜿蜒的河段的河流进行了观察。最后，几个数值模型已基准对物理比例尺模型的河流。
This paper presents a number of complex issues associated with the methodology and preliminary analysis of velocity and discharge measurements using various techniques applied to the River Blackwater, UK. An ADCP deployment procedure was adapted in order to take into account the difficulties of using such equipment in small rivers. The velocity profile in the middle of main channel has been measured using both ADCP and ADV, and averaged over a time scale of 800 s and 300 s respectively, to obtain a stable value. A discrepancy of approximately 6.8% was observed in the mean streamwise velocity between both measurements. A good agreement between surface velocity measurements using PIV and ADCP in cross-sections located in straight and meandering reaches of the river was observed. Finally, several numerical models have been benchmarked against a physical scale model of the river.
