Table 4. Exogenous factors used in modelling of fire behaviour for this study.

Parameter Characterisation methods Range
Slope Taken from site surveys and adjusted by the angle of fire spread in relation to the terrain -28° to 21°
Wind direction Modelled on a 250 m grid using Butler et al [50] from wind directions recorded for Cabramurra (63km SW of sites, closest high altitude station) and Canberra (20km E of sites, closest station) weather stations. Lee-slope directions were adjusted for dynamic channelling effects using a terrain filter developed by Sharples et al [51]. 0°-335°
Wind velocity Modelled on a 250 m grid using [50]from wind directions recorded for Cabramurra and Canberra weather stations, adjusted for the direction of fire spread relative to the wind. -21 to 30km/h
Air temperature Linear interpolation between upper and lower (Cabramurra and Canberra) values based on elevation. 12.5 to 37.6°C
Relative humidity Linear interpolation between upper and lower (Cabramurra and Canberra) values based on elevation. 13.0 to 63.5%
Dead fuel moisture Modelled using Gould et al [39] 3.6 to 13.7%
