This research examined existing and modified communication to community members who may be affected by natural hazards to derive evidence-based insights into risk and warning communication during the response phase of emergencies. Through this project, the research team developed an evidence base for the context of risk and warning messages across multiple channels and sources, constructed evidence-based warning messages that overcome ambiguity caused by conflict between warning messages and socio-environmental cues, optimised warning messages to improve community members’ readiness to act in accordance with emergency instructions, and translated research findings into practical tools tailored to the existing and emergent needs of end-users.
This research was targeted at assessing mitigation strategies to reduce the vulnerability of existing residential building stock in Australian floodplains. The project addressed the need for an evidence base to inform decision making on the mitigation of the flood risk posed by the most vulnerable Australian houses and complements parallel CRC projects for earthquake and severe wind. Through this project, the research team developed a building classification schema to categorise Australian residential buildings into a range of typical storey types, reviewed national and international mitigation strategies, and developed a floodproofing matrix to assess strategies for select story types. The results of this research form an evidence base to inform decision making by government and property owners on the mitigation of flood risk by providing information on the cost effectiveness of different mitigation strategies.

This project addressed the data and knowledge gaps and requirements for disaster resilience, resource assessment, emergency management, risk mitigation policy and planning. It identified the fundamental data requirements and modelling framework to derive exposure information to enable a better understanding of the vulnerability of people, buildings and infrastructure.
This study identified vulnerable legacy house types across Australia and developed cost-effective retrofits for mitigation damage during windstorms. These evidence-based strategies will aid policy formation and decision making by Government and industry, and provide guidelines detailing various options and benefits to homeowners and the industry for retrofitting typical at-risk houses in Australia. The final report presents an overview of the research approach used for this project including the selection of house types, the development of the Vulnerability and Adaptation to Wind Simulation software and the Internet-based guidelines, Weather the Storm.
Major findings of the research include the identification of the levels of hazard exposure which could lead to failure of structures and the other parameters affecting failure. Further, methods of modelling road structures under different loading regimes were developed with case studies of typical structures. New design approaches for building back better have been proposed for floodway structures based on parametric analysis of typical types of floodways. A major utilisation outcome of the project is a resilient floodway design guide, published in collaboration with the Institution of Public Works Engineers Australia Queensland.
This project developed better predictions and forecasts for extreme water levels arising from storm surges, surface waves, continental shelf waves, meteorological tsunamis, mean sea level rise and the transition from tropical to extra-tropical cyclones.
This project investigated the use of remote sensing data to improve modelled flood forecast skill and value. It developed optimal ways to constrain and update hydrologic flood models using remotely sensed soil moisture data. The project also proposed an algorithm for the monitoring of floods under vegetation, and investigated optimal ways to use remote sensing-derived inundation extent and level to implement and calibrate the hydraulic model. The results of this project enable improved predictions of flow depth, extent and velocity in the floodplain.
