Modelling the effects on the built environment of natural hazards, such as flooding, storm surges and tsunami, is critical for understanding the economic and social impact of these hazards on our urban communities. As part of this process, Australian National University (ANU) and Geoscience Australia (GA) have collaboratively developed an open source software program called ANUGA, to model water flow and in particular inundation events. Using this software we can help draft evacuation plans, design protective levees and design cities safely - reducing casualties and damage to property in communities affected by such disasters. In this talk I will give an overview of ANUGA, its use of python and other open source libraries and resources to provide a sophisticated modelling environment that can be easily expanded by advanced and naive users alike.
Associate Professor Stephen Roberts is currently Head of the Department of Mathematics at the Australian National University. Stephen works on finding efficient and robust methods for the solution of fluid flow problems associated with dam breaks, tsunamis, storm surge and flooding. In collaboration with members of the Risk Assessment group at Geosciences Australia, his work has been incorporated into an open source tsunami and flood modeling computer program called ANUGA. Used by local, state and commonwealth government to model risk from tsunamis and flooding, this work was presented on the ABC The New Inventors program.
