Model Pinpoints Factors Driving Extreme TOPICS IN THIS EDITION l RISK l TECHNOLOGY l NATURAL ENVIRONMENT ISSUE 137 DECEMBER 2014 MODEL PINPOINTS FACTORS DRIVING EXTREME BUSHFIRE BEHAVIOUR CONTEXT The WRF-Fire coupled atmosphere-fire model was used to investigate physical interactions between bushfire, local terrain and atmosphere, that drive lateral fire spread across steep leeward slopes. This dynamic mode of fire spread was observed in the 2003 Canberra bushfires and can result in extreme fire behaviour. BACKGROUND On 18 January 2003, bushfires in and around the Australian Capital Territory exhibited some of the most extreme fire behaviour ever witnessed in Australia. Using remote- sensing technology, including thermal and multispectral linescans, satellite imagery and aerial photographs, McRae (2004) presented Researchers used the WRF-Fire coupled atmosphere-fire model to examine dynamic fire evidence of extreme fire behaviour during spread observed in the ACT 2003 bushfires. the 2003 Canberra bushfires. He included a description of an “asymmetric wind-terrain SUMMARY interaction event” that occurred in a number In the 2003 Canberra bushfires, a number of unusual fires were observed in which of bushfires. In those events, the fire advanced bushfire spread sideways in a diagonal or crosswise direction to background winds. It rapidly across a leeward slope in a direction occurred alongside rapid and intense downwind fire spread due to spotting. The atypical approximately transverse to the background fire occurrence was on steep leeward slopes (a sheltered slope facing away from the wind) winds. In addition to this atypical lateral fire where background wind was mostly perpendicular to the terrain. spread, embers were launched by atmospheric The WRF-Fire coupled atmosphere-fire model was used extensively to examine both eddies and travelled downwind, resulting in a the physical mechanism driving the atypical lateral fire spread, as well as its sensitivity rapid and intense downwind propagation of to the fire environment conditions.

With rapid advances still being made in physical drivers of fires, it remains crucial to make detailed observations of fires to support research. The long-term benefits to fire agencies are immense, but require the collection of detailed field and airborne data, as well as weather and satellite data. As knowledge of dynamic modes of fire spread improves, fire agencies will be better placed to provide researchers with rich data on a broad range of fire events. This could potentially lead to improved operational predictability and management of bushfires. It is worth noting that there have been a number of incidents in recent decades where firefighters have been injured or killed when fires in rugged terrain suddenly became more severe. This has been largely due to unexpected changes in local wind conditions or through some dynamic interaction between the fire and its local environment. This specific work on VDLS improves our understanding of extreme fire behaviour, and in turn could help reduce the risk to firefighters working in extreme bushfire conditions. – Rick McRae, ACT Emergency Services Figure 2: Plan view of a fire whirl driving the lateral fire spread between a time of 50 and 53 min in Agencies one of the WRF-Fire simulations. The wind vectors and colours show the mid-flame height winds across the leeward slope.

In recent years a number of large scale disasters both onshore and offshore have become the focus of Australian State and Commonwealth disaster recovery efforts. These have provided opportunities to reflect on successful elements of 'community recovery' including what 'communities' do themselves to assist 'recovery' and what governments can do to enable and actively facilitate the 'recovery' process. Through an examination of a recent study on the recovery of people affected by the Australian Capital Territory (ACT) bushfires (known as the Canberra Bushfires) (Camilleri et al, 2007), this paper examines what helps and what hinders community capacity building, including the role of social networks and supports and community engagement activities.

    Making Sense of Disaster - Identity Challenges from a Bushfire Susan Slowikowski A thesis in fulfilment of the requirements for the degree of Doctor of Philosophy School of Humanities and Languages Faculty of Arts & Social Science May 2017 THE UNIVERSITY OF NEW SOUTH WALES Thesis/DissertationSheet Surname or Family name: Slowikowski First name: Susan Other name/s: Jennifer Abbreviation fordegree as given in the University calendar: PhD School: School of Humanities and Languages Faculty: Faculty of Arts & Social Science Title: Making sense of disaster - identity challenges from a bushfire Abstract 350 words maximum: (PLEASE TYPE) In Australia, bushfire accounts foralmost one-fifth ofproperty loss fromnatural disasters. In a country ravaged by bushfire, stories ofwidespread destruction are shared every summer. Bushfire is a constant and ongoing part ofAustralian history, identity and culture, causing extensive loss to personal property, public infrastructureand the natural environment. Research into how individuals create meaning frombushfire may provide insight into how these experiences shape resilience. This research aims to contribute to the emerging body of sensemaking literature by proposing a conceptual framework to address how memory curation influences sensemaking froma bushfiredisaster. The study also reflects on how identity shapes and is shaped by meaning creation processes over time. The research has developed a multifacetedunderstanding ofhow individuals create meaning fromtheir experiences in a natural disaster, and specifically the 2003 Canberra Bushfires. First, meanings derived from the memory curation process and shared through personal narratives, use language devices including metaphorical or emotive expressions and sensory images. Second, sensemaking is a natural progression in the memory curation process because meaning is constituted within these shared narratives.

    3J-1 Appendix 3J Cross-Border Issues and Australian Bushfires Table 3J-1 below contains 26 extracts from books, reports and papers, from 1983 through to 2005, which describe the impact of Australia's State-Territory borders and cross-border issues on operational responses to bushfires, and associated costs to individuals, communities and governments. These 26 extracts include 1 from 1983; 1 from 1998; 1 from 2000; 1 from 2001; 1 from 2002; 15 from 2003 (including reports on the January 2003 Canberra bushfires by the Canberra Times and the ACT Stateline television program, and the McLeod and Nairn Reports); 4 from 2004 (including the COAG Report by Ellis et al.), and 2 from 2005. 3J-2 Table 3J-1: Extracts on State-Territory Cross-Border Issues Arising in Relation to Australian Bushfires Source Selected Extracts Whitlam (1983: 40-42): The cost of Australian federalism is horrendous enough when the federal government and a state government or state governments duplicate services for which there is a commonly accepted standard. The cost is higher still when they supply services for which there is not such a standard. The most notorious case in Australian history concerned the railways where the states adopted three different gauges. ... The break of gauge syndrome has another manifestation which was brought to my attention by a fire in the bulk sugar terminal at Townsville in May 1963. The terminal's own fire fighting equipment could not cope. The adjacent Harbour Board could not assist, since its hoses could not be coupled with those of the terminal. Nor could the hoses of the City Council nor those of the federal departments of Civil Aviation and of Air at the airport.

  • Australian Bush Fire Impacts
    Australian Bush Fire Impacts A bushfire is a fire that occurs in the bush (woodland or grassland of Australia) and naturally caused by lightning strikes. However, the natural fire regime was altered by the arrival of humans in Australia. As a consequence fires became more frequent, and fire- loving plant species such as eucalyptus greatly expanded their range in Australia. Bush fires have caused Satellite image of the fires in Eastern Victoria during the afternoon of 7 February 2009. both property, By 8 February, smoke from the bushfires had reached as far as New Zealand . stock and wildlife [http://www.stuff.co.nz/stuff/th epress/4841601a6009.html] loss.

  • The Stabilisation and Interpretation of the Mount Stromlo Director's
    Understanding Through Fabric: The Stabilisation and Interpretation of the Mount Stromlo Director’s Residence Amy Jarvis Proceedings of: Page 1 of 17 Understanding Through Fabric: The Stabilisation and Interpretation of the Mount Stromlo Director’s Residence Introduction The Mount Stromlo Observatory is an iconic and memorable place. The site has strong associations with the development of Canberra, scientific endeavour in the Capital and of the growth and success of the Australian National University (ANU). After the Observatory was almost levelled in the 2003 Canberra bushfires, the ANU and its Research School of Astronomy and Astrophysics (RSAA) were forced to change the way they thought about managing the site. In one terrifying afternoon, the site was transformed from a fully functioning scientific facility to a landscape containing very few surviving buildings, a large number of half standing buildings and a mass of burnt trees, all surrounded by magnificent ponds of melted metal and glass. All working telescopes were damaged or destroyed. The main administration building and the site electrical, mechanical and optical workshops were completely gutted. Nine residences were lost, one of these was the grand two-storey Director’s Residence. There has been extensive academic debate on the best practice conservation and management of ruins. Some of the texts suggest the idea of the ‘romance of a ruin’ and the merit of letting nature take its course - ‘once a ruin, always a ruin’ (Department of the Environment 2013:9). Conversely, some research advocates strongly for reconstruction, especially where adequate information is available. Each approach needs to be assessed on a case by case basis, and in Page 2 of 17 this case, a combination of both approaches were implemented in the conservation, management and interpretation of the ruins of the Mount Stromlo Observatory, and in particular it’s iconic Director’s Residence.
