Technical Points and Case of Optimal Setting of Water Intake Platform for Automatic River Water Quality Monitoring Station
An automatic water quality monitoring station is essential for acquiring water quality data.Relevant national standards have been set for choosing the locations of automatic water quality stations.However,the water intake of automatic stations is prone to be affected by river erosion and human activities,which might affect the representativeness and accuracy of water quality monitoring data.This study summarized the key technical points of the optimal setting of the water intake platform:The sites should be on river segments which are straight as much as possible or not affected by erosion;the water depth at the platform position with 99％water level assurance rate should be more than 1 m;and the water flow velocity should be at least 30％of the mean velocity of the river section.Taking the station of Aqi Bridge as an example,this article furthermore analyzed the influences of downstream power station operation and river erosion on the water intake platform,unveiled the causes for insufficient representativeness of water samples,and further put forward recommendations for optimizing the water intake location of Aqi Bridge water quality auto-monitoring station.
