Flood study

Alexandra Canal Flood Study

The purpose of this Flood Study is to identify local overland flow as well as mainstream flow and define existing flood liability. This objective is achieved through the development of a suitable model that can also be used as the basis for a future Floodplain Risk Management Study and Plan for the study area, and to assist the Inner West Council (IWC) when undertaking flood-related planning decisions for existing and future developments. The primary objectives of this study are to:

  • prepare suitable models of the catchment and floodplain for use in a subsequent Floodplain Risk Management Study;
  • provide results for flood behaviour in terms of design flood levels, depths, velocities, flows and flood extents within the study area;
  • prepare maps of provisional hydraulic categories and provisional hazard categories;
  • determine provisional residential flood planning levels and flood planning area;
  • prepare preliminary emergency response classifications for communities; and
  • assess the sensitivity of flood behaviour to potential climate change effects such as increases in rainfall intensities and sea level rise.
