Auckland City Stormwater Modelling

The central downtown region of Auckland City has primary piped networks and secondary flow paths through street junctions, interlinked by stormwater catchpits. Although other software could be used for steeper catchments feeding the central region, and for the sanitary sewage system, the Council established that the sophisticated major/minor flow model required for the central city needed key features of Mike 11 UD, which have been extended further in the latest version of AULOS . The diagram shows the match between measured and modelled flow.
