Urban rainwater drainage regulation and storage calculation model and method

The invention provides an urban rainwater drainage regulation and storage calculation model. Through the four years of district test and joint simulation research, the steady theoretical basis, the high-precision calculation deduction and the particular technical development method are established, the technical innovations and correction capability according to the local conditions are provided, and the rainwater flow quantity calculation of different cities and different areas in one city is realized. For the profound research on the system of draining water into the drainage receive area through a pipeline network, especially for the slope flow entering the pipeline network, the strict regulation and storage model (hydraulics physical model) is established under the condition of gully control, which use neither the black-box model nor the conceptual model but is based on the GIS (geographic information system) technical platform. The established rainstorm water regulation and storage model can truly reflec
