【 摘 要 】

Nowadays, an ecological water diversion project is executed in Wenzhou city for the purpose of river network water quality improvement. Due to the flow rate of the water diversion project is relatively low, the utilization of sluice gates along Oujiang River becomes important, which can help to accelerate the flow velocity and redirect the water flow in river network. In this study, an experiment is designed and executed near Huiqiao sluice gate, both water flow and water quality are observed at three monitoring sections before and after the sluice gate's opening. The comparison between background and measured data shows the improvement of water quality in experimental area, which confirms the function of Huiqiao sluice gate. A comprehensive sluice gate regulation and control plan is anticipated in the future to further improve the river network water quality in Wenzhou city.
