Abstract: Non-static series water quality models of Suzliou’s River Network are proposed in this paper by means of water quality prediction for the purpose of integrated control of water pollutionin Suzhou City. The models inclode the following ones:1. "Water quality model of network water body" to predict seasonal variations of water quality in Suzhou’s network water body;2. "Water quality model of different river reaches" to predict spatial variations of water quality in different river reaches;3. "Water quality model of river network" to predict hourly variations of water quality in different sections of the river network.The accuracy of these models has been proved to be satisfactory. Simulation and prediction of water quality in this network have been carried out as well.
