Abstract
Dangtu Hydrological Station is located in the lower reaches of Guxi River,Hebin Road,Gushu Town,Dangtu County.The downstream of the station is the estuary of the Yangtze River and belongs to the tide-induced river section.The water level flow relationship of the station is affected by the comprehensive influence of the incoming water from the Qingyi River in the upper reaches of the Qingyi River and the backflow of the Yangtze River tide tide,and the water level flow relationship cannot be established normally,and the relationship points are scattered.For a long time,the eight representative tide test method of the lunar calendar time has been adopted,and the cable flow rate meter method is used to measure more than 300 flows every year,which is a large workload.In early 2023,the station built a new bottom-mounted ADCP traffic online monitoring system.After the period test from January 2023 to August 2023,the V-ADCP online traffic system was used as the main monitoring,and the hydrological cableway test was supplemented,and the voyage-type ADCP was checked regularly,which was better completed in the monitoring of the station's traffic process.Two fixed bottom V-ADCP probes are installed on the riverbed of the basic flow measurement section of Dangtu Station to form an online flow monitoring system,realizing online flow monitoring of the station.It can provide useful reference for measuring stations that cannot establish a relationship in water level flow due to the influence of tide water level.关键词
