Fire Note 137: In the 2003 Canberra bushfires, a number of unusual fires were observed in which bushfire spread sideways in a diagonal or crosswise direction to background winds. It occurred alongside rapid and intense downwind fire spread due to spotting. The atypical fire occurrence was on steep leeward slopes (a sheltered slope facing away from the wind) where background wind was mostly perpendicular to the terrain.
Fire Note 136: This Fire Note reports in more detail on the smoke dispersion modelling work undertaken as part of the Fire Impact and Risk Evaluation Decision Support Tool (Fire DST) project,providing a better understanding of smoke exposure risks from both bushfires and prescribed fires.
Fire Note 134: This Fire Note outlines research undertaken within the bushfire-prone communities of Roleystone and Kelmscott in the Perth Hills, about 45 minutes east of Perth, Western Australia. The researchers surveyed householders to assess the role of anxiety and worry in relation to how people process bushfire safety and warning information and the impact of these emotions on how they prepare for threat.
Fire Note 135: This Fire Note details research that estimates toxic emissions commonly encountered by firefighters extinguishing fires in semi-rural communities at the rural-urban interface.
Toxic emissions from burning houses, cars and other household materials during bushfires may pose a range of health risks to communities and their firefighters.
Fire Note 133: The national research featured in this Fire Note investigated the community and householder characteristics that contribute to bushfire preparedness in Australia's bushfire-prone areas.
The findings are based on four separate but related studies (both qualitative and quantitative) conducted over two years in a total of 288 fire-prone communities across four states: Western Australia (WA), Victoria, South Australia and Tasmania.
This is a paper presented at the 2013 Bushfire CRC Research Forum.
Fire Note 132: Offers a new way of thinking about bushfire preparedness and its measurement. The study defines preparedness in terms of three householder goals: stay and defend, evacuate safely or improve the property’s fire resistance when left unattended. The research also offers a new framework for measuring householder preparedness in relation to these differing goals. The measures will be useful for assessing the effectiveness of community safety campaigns, especially those targeting specific goals, such as preparing communities to evacuate.
Fire Note 131: In October 2013, bushfires swept across parts of New South Wales, leaving a trail of destruction and loss. The NSW Rural Fire Service (NSW RFS) commissioned the Bushfire CRC to conduct community-focused research with a number of communities hit hard by the 2013 bushfires in the Blue Mountains, Southern Highlands and Port Stephens. The aim was to understand how people prepared for and reacted to these disasters and assist future development of emergency management responses, community education and public safety initiatives.
This report details the third of three case studies used to explore spatial modelling of RHF incident on a house during a fire as an alternative of the AS3959 approach for hazard classification. This case study uses data collected during and after the fire that occurred at Springwood in NSW in October 2013. The study develops detailed modelling of radiant heat incident on houses using topographic information, while accounting for vegetation (fuel) structural variability across the landscape.
Fire Note 130: Features the findings of four research projects on the impact of fire on water quantity and quality, as well as changing carbon stores (above and below the ground). Among its key findings, the research shows that controlled burning in fire-prone eucalypt (mixed species) forests in and around major water catchments is unlikely to have an impact on water supplies. Traditionally, it was thought that all forests recovering from fire took a lot of water from adjoining water catchments and reservoirs.
