Since its first version in 1971, scientists and practitioners have continuously enhanced the source code, which is mainly written in C since version 5. It includes a hydrologic model for rainfall-runoff simulations and a dynamic hydraulic model for routing along a watercourse or drainage system. The Stormwater Management Model (SWMM) developed by the US Environmental Protection Agency is a well-established software in the field of urban drainage modelling. An application example is presented to demonstrate the basic features and usage of the plugin. #PCSWMM IMPORT CAD PIPE NETWORK FREE#We developed a free and open-source QGIS plugin to generate SWMM models from geodata and to import existing SWMM input files into QGIS. Existing approaches were script-based or required commercial all-in-one products. SWMM contains neither an import function for geodata nor processing tools as provided in geographic information systems (GIS) such as the open-source software QGIS. Since the required data regarding sewer geometries and river systems are usually available as spatial data in a GIS environment, there is a need for user-friendly interfaces for the model setup. For a new SWMM model, objects such as nodes, links and catchments can either be drawn via SWMM’s graphical user interface (GUI) or specified manually in a plain text file in “.inp” format (“input file”). It has been applied in numerous practical works and research projects. SWMM is an open-source model and software developed by the US EPA for the simulation of rainfall-runoff and routing in water bodies, sewer systems and wastewater infrastructures. ![]()
