The invention provides an intelligent sponge city flood forecasting method, which belongs to the technical field of city management, and comprises the following steps: constructing a research area plane calculation grid; determining a hydrological hydrodynamic time history continuous calculation time interval between the grids; extracting high spatial resolution grid elevation and land utilization/coverage information; assigning values to the grid precipitation time history data; assigning values to the grid production and confluence parameters; taking the grid elevation, the land utilization/coverage information and the rainfall and runoff production and confluence parameters as a model operation database, integrating a hydrological hydrodynamic theory, and constructing a hydrological hydrodynamic model by using the method; verifying the hydrological hydrodynamic model; and based on the simulation result of the hydrological hydrodynamic model, performing basin runoff production and confluence and flood disas
