摘要
在长江上游水库调度的影响下,下游水文站流量变化频繁,采用常规方法难以准确测量到流量变化过程。为此,长江干流黄陵庙水文站利用水平式声学多普勒流速剖面仪(H-ADCP)进行了流量在线监测。介绍了在线监测系统的流量推算原理、信息采集系统结构以及实时信息处理过程。将H-ADCP实时监测结果与传统方法所测流量进行了对比分析,结果表明,其测量误差和随机不确定度均较小。
Under the influence of reservoirs regulation at upper Yangtze River,the discharge of hydrological stations at downstream changes frequently,so it is difficult to correctly monitor the changes of discharge using conventional method. Therefore, for downstream Huanglingmiao Hydrological Station of Three Gorges Project,H- ADCP（ Acousitc Doppler Current Profiler） was adopted for online discharge monitoring. The discharge estimation principle,structure of information collection system and online information processing are introduced. The monitoring results of H- ADCP are compared with those of conventional methods and the results show that the error and random uncertainty are smaller.
