Flood study

Woolgoolga Flood Study

Woolgoolga is situated on the north coast of NSW approximately 20km north of the city of Coffs Harbour. The Woolgoolga Lake catchment occupies a total catchment area of around 22 square kilometres, extending from the Coast Range in Wedding Bells State Forest, and flowing east to the coast via Woolgoolga and Poundyard Creeks.

The primary objective of the Flood Study is to define the flood behaviour of the Woolgoolga Lake catchment through the establishment of appropriate numerical models. The study has produced information on flood flows, velocities, levels and extents for a range of flood event magnitudes 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, 2% AEP, 1% AEP, 0.2% AEP and PMF event; and
  • Presentation of study methodology, results and findings in a comprehensive report incorporating appropriate flood mapping.
