    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.
