The Flood Study had three main components:

  1. Review of available hydrologic and hydraulic data and previous investigations. As mentioned, a Brief was prepared for a cross sectional survey of the Southern Tributary to fill in gaps in the survey data. Historic flood marks identified by the Community Newsletter were also levelled during the creek survey. The Bureau of Meteorology and Sydney Water supplied rainfall data for the historic storms identified in previous investigations on flooding on Flat Rock Creek and by the Community Newsletter.
  2. The hydrologic component, which included refining and testing of the hydrologic model of the catchment, estimation of design storm rainfalls and their application to the model to assess flows.
  3. The hydraulic component, which comprised the testing of the hydraulic model of the open channel section of Flat Rock Creek and the preparation of the Southern Tributary model and the definition of the water surface profiles, flows and velocities for the design floods.
