Description

technical field [0001] The invention relates to the technical field of urban waterlogging simulation, in particular to an urban waterlogging prediction method and system based on a fast waterlogging simulation coupling model. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] With the acceleration of urbanization and the change of global climate, the law of production and confluence in urban areas and the conditions of the underlying surface have undergone tremendous changes. Rainfall is one of the main disaster-causing factors of urban waterlogging, and the frequency of heavy rainfall during the flood season is also increasing year by year. [0004] During the flood season with frequent rainstorms, the simulation and prediction of the submerged water depth and range of urban areas is crucial for flood risk management and government decision...
