Short summary
This CA model can be easily established using commonly available basic urban geographic data with little preprocessing. It considers detailed urban features such as buildings and inlets, reproduces the changing extent and depth of flooded areas at the catchment outlet with an accuracy of 4 cm in water depth, and adequately represents the flow dynamics in the inundation process; furthermore, the model is computationally efficient for city emergency management.
