Improve flood information during extreme events

To assess their residual risk above the floor planning level, Sunshine Coast Regional Council required floodplain hazard mapping for events larger than the 1% AEP event. The areas of interest included Noosa River, Paynter Creek, Petrie Creek and Eudlo Creek. Previously hazard mapping had only been produced for events up to the 1% AEP.

WMS updated existing hydrologic (XP-RAFTS) and 1D hydraulic (MIKE 11) models to remove instabilities and reflect present day modelling techniques. The updated models were used to map flood hazard within the areas of interest for a range of rare design events. The models were also used to inform Council’s Disaster Hub and formed the basis of future flood related projects in Council.
