A long term simulation for a sewer network by dynamic flow routing models is very time consuming. The alternative hydrological methods (e.g. until hydrographs) have the disadvantage that they are unable to simulate backwater conditions which may significantly effect the flow hydrograph. As one possible solution this payer presents a simulation concept which includes hydrological components to model the effects of backwater or overtopping street level. However, each model component requires a calibration on dynamic routing results because the investigations showed that each sewer system reacts very individually at backwater conditions. This new concept was developed and verified at eight sewer systems.
