Résumé
Delineation results Conclusions References Context Evaluate the effect of the spatial distribution of SUDS in urban catchment Combined Sewer Overflow impacts Case study n°3 Case study n°2 Case study n°1 available data Scenario n°1 Scenario n°2 Scenario n°3 Scenario n°4 CSO structure position, Land use maps CSO structure position, Land use maps DEM 5m x 5m CSO structure position, Land use maps Network plans CSO structure position, Land use maps, DEM 5m x 5m, Network plans CSO structure Pipes Nodes • Mimicking the network following the main roads provides a good approximation of the main branches of the network • Current results show a better estimation of total runoff volume when topography is available.
