Integrated Modelling in the Auckland Region (New Zealand): (1) Linking Drainage and Receiving Environments and (2) Regional and Local Flood Hazard Mapping
Abstract:To respond proactively to legislative requirements that require information and analyses in New Zealand, integrated modelling approaches have been undertaken in the Auckland region in the last ten years. Part 1 describes linking urban stormwater and combined/sanitary sewer overflow drainage modelling with receiving environment modelling to assess the risk to public and ecological health. Adverse ecological effects are predicted through projecting long term accumulation of heavy metals (zinc) in estuarine bed sediments. MOUSE (hydrology, pipe network, and overflows), STORMQUAL (stormwater quality), RMA-2 (hydrodynamics), PTS (particle tracking system), BACTO (bacteriological), and MUD (contaminant accumulation) computer models were used. Part 2 details modelling of flood hazards at different scales: regional and local. The regional flood hazard assessment used MIKE 21, whereas the local scale modelling used MIKE FLOOD that linked MIKE 11 and MIKE 21. Sample results are presented and observations made about the model approaches and information generated in these studies.
