Flood vulnerability functions for buildings (often called stage-damage functions) relate flood damage to the depth of inundation in the building. These functions are generally used in assessing flood risk and in evaluating cost-effective mitigation strategies for flood risk management. Flood vulnerability models are usually developed for a certain location by following empirical, analytical or heuristic procedures. They can be developed for a representative building type (detailed approach) or representing a mix of building types (generalised approach).

Geoscience Australia (GA) has developed a suite of flood vulnerability functions for a range of building types (detailed approach) that covers residential, commercial, industrial and community building land use types. These functions are best used in detailed micro level studies and are applicable to the highest resolution of building exposure information with flood vulnerability directly attributed to individual buildings.

This paper describes research with the National Flood Risk Advisory Group (NFRAG), the Australian Institute for Disaster Resilience (AIDR), state and local governments and industry to translate detailed vulnerability information into practical guidance for flood risk managers undertaking studies under the floodplainspecific management process as outlined in the AIDR Handbook, Managing the Floodplain: A Guide to Best Practice in Flood Risk Management.

This research derives generalised vulnerability functions for a mix of building and land use types. The generalised curves can be utilised at meso or macro level study and are intended to be applied at a resolution of built environment information readily available to floodplain managers.
