Secondary Development of Storm Water Management Model SWMM Based GIS
Taking Xinhepu region in Guangzhou city for an example, the method of double layers drainage system and open data interface of SWMM model are used to achieve the integration of SWMM model and ArcGIS system on the platform of Visual Basic 6.0.And the water-logging model based GIS is developed.Finally, submerging state for different return period storm is analyzed.The results show that the model has goodl precision and reliability.
