7.3    Parameters used in the bushfire behaviour modelling
East bushfire attack
This modelled fire burns up-slope through Eucalyptus spp open forest to attack from the east.
   • Fuel loads used are the “woodland” fuel loads of Australian Standard AS3959 of 15t/ha
       surface fuel & 25t/ha total fuel.
   • Separation of the house from the hazard: 14m
   • Slope in the vegetation = 9.60.
   • Site slope = 9.60
   • Fire run 160m from the next door house leading to a reduction of 0.6 of the of the potential
       full quasi-steady state rate of spread and and
   • Flame width = 100m
North bushfire attack
This modelled fire burns up-slope through Eucalyptus spp open forest to attack from the north.
   • Fuel loads used are the “woodland” fuel loads of Australian Standard AS3959 of 15t/ha
       surface fuel & 25t/ha total fuel.
   • Separation of the house from the hazard: 19m from across Little Springs Lane,
   • Slope in the vegetation = 10.50.
   • Site slope = 9.20
   • Fire run 300m from the next door house leading to a reduction of 0.7 of the of the potential
       full quasi-steady state rate of spread and
   • Flame width = 100m
