Noosa Shire Council Coastal Hazard Mapping                                                               8
Storm Tide Hazard Assessment




2.3      Coincident Catchment Flooding & Storm Tide
         The coincident Noosa River catchment flooding and storm tide hazard depth and extent for the
         CHAP planning horizons are presented in Appendix B. As described in Section 2.1, coincident
         rainfall river flooding and storm tide hazard was recently assessed by WMA Water (2017a; 2017b).
         Their report describes the 1 in 100 AEP as a combination of flow, rainfall and tide conditions, of
         which the probability of occurrence is unknown, but likely to be rarer than the 1 in 100 AEP. The
         maps provided in Appendix B are simply a presentation of the WMA Water peak inundation depth
         assessment results. As noted above, inundation velocity information is also available and may be
         used to inform the Noosa CHAP risk and vulnerability assessment.
