Combined Catchments of Whartons, Collins and Farrahars Creeks, Bellambi Gully and Bellambi Lake - Flood Study

The contiguous catchments of Whartons, Collins, Farrahars Creeks, Bellambi Gully and Bellambi Lake are located between 6 and 10 km north of the Wollongong Central Business District. The streams which drain these catchments run through the suburbs of Bulli, Woonona, Woonona East, Russell Vale, Bellambi, Corrimal and Corrimal East. The Whartons Creek catchment defines the northern limits; and the Bellambi Lake catchment the southern limits, of the study area. The flood study had three components:

  1. Review of available hydrologic and hydraulic data and previous investigations
  2. A hydrologic component (RAFTS)
  3. A hydraulic component (TUFLOW)

The study objective was to define flood behaviour in the study creeks under current conditions in terms of flows, levels and velocities for floods ranging between 5 and 500 years average recurrence interval, as well as for the Probable Maximum Flood.
