Upper Orara River Flood Study

The Upper Orara Riveer Flood Study has been prepared for Coffs Harbour City Council to define the existing flood behaviour in the floodplain of the Upper Orara River and Bucca Bucca Creek and establish the basis for subsequent floodplain management activities. 

The study has produced information on flood flows, velocities, levels and extents for a range of flood events​ under existing catchment and floodplain conditions. Specifically, the study incorporates:

  • Compilation and review of existing information pertinent to the study and acquisition of additional data including survey as required;
  • Development and calibration of appropriate hydrologic and hydraulic models;
  • Determination of design flood conditions for a range of design event including the 20% AEP, 5% AEP, 1% AEP, and PMF event; and
  • Presentation of study methodology, results and findings in a comprehensive report incorporating appropriate flood mapping.
