The two-dimensional unsteady flow dynamics model uses Saint-Venant equations for basic mathematical equation to simulate open channel flow law of motion. Taking Foshan City center as range of study, future short-term rainfall which is predicted is one of the input conditions. Combining with high precision GIS city map, underground drainage network data, freshwater river and outer river water level, pumping station operation and so on, the two-dimensional unsteady flow dynamics model is used to simulate the effect of city by storm. City rainstorm waterlogging models and urban waterlogging warning system are used for urban waterlogging warning. Through the real-time monitoring and management of hydrological information, rainstorm waterlogging simulation, flood warning, hazard mapping and GIS applications etc, it provides decision-making basis and technical support for flood control, waterlogging forecast and emergency dispatch in Foshan.
