| Abstract: | A stochastic dynamic water quality model was deduced by using Liouville theorem, and its numerical algorithm was proposed. The model can be used in simulation and control of water quality in tide river segment. A great deal of information, such as the main trend and range of variation for a pollutant's concentration, the risk which a pollutant's concentration exceeds its limit value, and the relation between the time and possibility of exceeding the concentration limit value, can be obtained through solving this model. It was showed that the model was able to show the effects of uncertain change in the concentration on the water pollution control program when it was used in Jiangmen River. |
