5. Conclusions
To sum up, the following conclusions can be made:
(1) An approach for predicting the effect of fire run distance on bushfire behaviour has
    been developed on the basis of the existing time dependant rate of spread equation
    developed by Cheney.
(2) By utilizing the established approach, the implications of fire run distance for rating
    bushfire hazard and prescribing APZs have been analysed for different fire
    scenarios.
