A modelling tool for simulation of sources and fluxes in wastewater systems: Focus on stormwater source control
Paper i proceeding, 2005

A modelling tool called STORM/SEWSYS has been proposed that makes it possible to simulate different scenarios of stormwater source control practices. Source control is an important method to reduce runoff volumes and peak flows, and at the same time improving the stormwater quality. The modelling concepts of two previously developed models, STORM and SEWSYS, have been combined and integrated to make it possible to use the new tool to simulate different stormwater source control practices. Various structural measures such as detention and re-use, swales and soakaways, catch-basins, wetlands, ponds, porous paving, and non-structural methods like public regulations or street sweeping are source control techniques that have been incorporated in the modelling framework of the tool. The STORM/SEWSYS model provides simulation techniques to evaluate changes to the hydrological cycle and hydrological risks in urban catchments. A detailed pollutant transport module where pollutants from different activities in the urban area are separated in their respective origin; material corrosion, brake wear, tyre wear etc. is included in the model and facilitates quality source control. This paper describes the new integrated sources and flux model STORM/SEWSYS and discusses the new possibilities the modelling approach will bring forward.
