3.3      CALCULATION OF POTENTIAL BUSHFIRE INTENSITY
The Potential Bushfire Intensity of each identified sub-unit has been calculated by inputting the site-
specific input parameters discussed in Section 2.1 into the FLAMESOL computer model. FLAMESOL is a
Method 2 assessment methodology under AS3959:2018 and uses industry standard bushfire equations
and allows numerous input variables to be adjusted including fuel loads, fire danger index, site slope and
distance to vegetation. Table 1 details the Potential Bushfire Intensity classes and their corresponding
potential fire-line intensity (kW/m) values as prescribed within Leonard et. al. 2017. The FLAMESOL
modelling used to determine the SPP Potential Bushfire Intensity classes has been included as Appendix
B.
Table 1 – Potential Bushfire Intensity Classes

 POTENTIAL BUSHFIRE INTENSITY                           POTENTIAL FIRELINE INTENSITY

 Very High                                              >40,000 kW/m

 High                                                   20,000-39,999 kW/m

 Medium                                                 4,000 – 19,999 kW/m

 Low (no hazard)                                        <4,000 kW/m


Figures 1-3 are presented below and have been prepared as per the above referenced methodology.
