摘要：To achieve fast and efficient flood modelling for urban area, a two-dimensional cellular automata based model was developed and further coupled with a hydrological model. The model was implemented in parallel environments and tested by an analytical solution and a real word case. The analytical case results showed that the model is capable of simulating water-depth under a reasonable slope threshold and grid resolution condition using only a short computational time. Slope threshold and grid resolution are the two key factors affecting the computational efficiency and model accurcay. The introduction of the state update interval significantly improved the computational efficiency. In the case of the real world example, the results were also in reasonable range.In general, this model can be applied to rapid flood analysis for large urban areas.
