| Abstract: | We proposed a practical model for water pollution accidents.The four-point implicit difference scheme was used to discretize the governing equations.Then a geographical information system(GIS) was employed to realize the real-time dynamic visualization of pollution simulating results on the ArcGIS platform.Finally,we employed the model in the public safety emergency platform with an example.The model shows simplicity,easy realization,high computing speed,high efficiency and good stability,and provids an effective assistant tool and decision-making foundation for water pollution accident emergency disposal with the intuitive and dynamic visualization of pollution information. |
