During a disaster responsibility for animals lies with the owner. However, owners are often ill-prepared for themselves and their animals, which can lead to people risking their lives by failing to evacuate or evacuating too late, which endangers both human and animal lives. This recognition that animals need to be considered and integrated into emergency management and disaster preparedness, response, and recovery poses additional challenges for traditional responding. Extra preparation, knowledge and skills are required to ensure the safety of animals, their owners, and responders.

In this context, animal emergency management has emerged as a relatively new area, with a more complex and often less experienced set of stakeholders requiring integration and coordination.

This study, now in its utilisation phase, sought to address the lack of Australian research by identifying challenges for end-users and studying the disaster experiences of animal owners and responders. Subsequent publications have led to an extended knowledge base, and identification of best practice approaches.

Research team:
This project is applying physics-based approaches to fire scenarios. It attempts to simulate fire with unprecedented detail and in the process obtain useful application tools for end-users.
This study is identifying the thresholds beyond which dynamic fire behaviour becomes a dominant factor, the effects that these dynamic effects have on the overall power output of a fire, and the impacts that such dynamic effects have on fire severity. This will necessarily include consideration of other factors such as how fine fuel moisture varies across a landscape. The research team is investigating the conditions and processes under which bushfire behaviour undergoes major transitions, including fire convection and plume dynamics, evaluating the consequences of eruptive fire behaviour (spotting, convection driven wind damage, rapid fire spread) and determining the combination of conditions for such behaviours to occur (unstable atmosphere, fuel properties and weather conditions).
Research team:
This research into interactions with topography, potential for pyro-convection, potential for three dimensional interactions, potential for winds to change substantially around a fire, water vapour dry slots, plume development and spotting process will be integrated into a formal, quantitative system for use with the current fire forecasting system.

Fire behaviour in dry eucalypt forests in Australia (and in many other vegetation types to a lesser extent) is characterised by the occurrence of spotfires—new fires ignited by the transport of burning debris such as bark ahead of an existing fire. Under most burning conditions, spotfires play little role in the overall propagation of a fire, except where spread is impeded by breaks in fuel or topography and spotfires allow these impediments to be overcome. However, under conditions of severe bushfire behaviour spotfire occurrence can be so prevalent that spotting becomes the dominant propagation mechanism and the fire spreads as a cascade of spotfires forming a ‘pseudo’ front. It has long been recognised that the presence of multiple individual fires affects the behaviour and spread of all fires present. The converging of separate individual fires into larger fires is called coalescence and can lead to rapid increases in fire intensity and spread rate, leading to the phenomenon of a ‘fire storm’. This coalescence effect is frequently used in prescribed burning, with multiple point ignitions used to rapidly burn out large areas.

The team has demonstrated the performance advantages of fire propagation models incorporating curvature dependence when applied to simple wind-driven fires at both laboratory and field scales. The research has also produced fundamental insights into how the shape of the fire line affects the dynamic behaviour of the fire as a whole. Coupled fire-atmosphere modelling was used to investigate how fire-induced air movements (pyroconvection) can produce significantly enhanced rates of spread for certain fire shapes.

This new project commenced in July 2017, and aims to produce new and innovative ways of integrating urban planning and natural hazard risk management. It will increase the understanding of what planning and emergency management can and cannot do, separately and in synergy, and develop new approaches to applying tools and methods available to planning systems to the design and management of communities as they change.
This new project began in July 2017. It will investigate the development of a pilot capability to make useful predictions of community impacts of extreme weather on residential property, improving timely mitigation actions. This pilot project will focus on severe weather events (damaging winds and heavy rain) impacting eastern Australia – events in areas where most of our population is concentrated, particularly the coastal regions of southern Queensland, New South Wales and eastern Victoria. These events, which include East Coast Lows, can occur at any time during the year, with gale or storm force winds damaging mainly coastal areas, and widespread rain damaging residential properties through rain ingress.
