Flood study

Hewitts Creek Incorporating Slacky, Tramway, Woodlands & Thomas Gibson Creeks Flood Study

The study catchment forms part of the Northern Wollongong coastal sub-basin and incorporates the subsidiary catchments of Slacky, Tramway, Woodlands, Hewitts and Thomas Gibsons Creeks. They are located in the northern suburbs of the City of Wollongong on a narrow strip of coastal land flanked by the Illawarra Escarpment to the west and the coastline to the east. The combined creek system drains an area of some 7.5 square kilometres of mixed residential, retail, light industrial and forested land. The primary objectives of this study include:

  1. establishing the existing flood behaviour within the study catchment;
  2. determination of flooding characteristics in terms of flood extents, levels, contours, depths and velocities;
  3. provide the basis for assessing risk of dwelling inundation, property accessibility, evacuation and other hazards resulting from flood; and
  4. establish calibrated models (hydrologic and hydraulic) which can be subsequently used to carry out the Floodplain Risk Management Study.
