H-ADCP流量在线监测方案在高坝洲的应用与改进

Application and Improvement of H-ADCP Online Monitoring Program at Gaobazhou Station

高坝洲水文站的水位流量关系,受上游水利工程调蓄、长江回水顶托、测站控制不佳的综合影响,关系点据散乱。经过试验,采用H-ADCP在线流量监测为主,水文缆道测验连时序法作补充,基本解决了该站的流量过程监测。在主洪道上修建H-ADCP监测台,实现了该站的流量在线监测。为水位流量关系复杂的测站,提供了流量在线监测的成功范例。

The relationship between water level and discharge at the Gaobazhou station is affected by the comprehensive influence of upstream water conservancy project regulation,Yangtze River backwater support and poor control of station.The relationship points are scattered.After testing,H-ADCP online traffic monitoring was adopted as the main method,and hydrological cable test with sequential method was taken as sup-plement,so as to basically realize the station flow process monitoring.The H-ADCP monitoring station was constructed on the main floodway to realize the on-line monitoring of the flow of the station.It is a successful example of on-line traffic monitoring for stations with complex water level and flow rates.
