Smart city is the emerging pattern of city development. However, in recent years, frequent urban floods have brought serious challenges to the management and development of smart cities. Urban flooding simulation is not only one of the key technologies of city flood control and mitigation, but also an important decision support tool for smart city disaster risk and emergency management. This article first indicates the connotation of smart city and smart water, and analyzes the new requirements of smart city development and management on urban flood inundation models. Second, it discusses the newly available data support of urban flood simulation models brought by the development of smart cities, and compares three existing hydrological models from the perspective of city emergency management decision-making. Third, this article points out that under the support of big data and technology of smart cities, the hydraulic-based distributed urban flood simulation models have a promising prospect in application. By analyzing the development of urban flood simulation models, we conclude that micro-level simulation, integration with remote sensing and GIS technologies, and emphasis on spatiotemporal process of flood inundation and smart service are the inevitable trend of development of urban flood simulation models.
