Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
This paper focuses on piecewise linear growth model of water quality about the river. The experiment was performed on South Sewage Discharge River of a certain Coastal City, in China. Physical, chemical parameters such as water temperature (T), turbidity (Tur) were measured over a one-year period including dry period, level period (May), wet period, level period (Oct.). Based on multilevel models, piecewise linear growth model of primary pollution factors (COD, NH3-N) are established. Among them, three piecewise linear growth model of COD and four piecewise linear growth model of NH3-N can comparatively accurate reflect growth trend of water quality along different water period. These models can provide scientific foundation for general regulation and management of rivers.
