Appendix B - Bushfire Hazard Assessment

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 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.
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                                                       <4,000 kW/m

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