Overview
Bushfire Conference 2006 – Brisbane, 6-9 June 2006
The inclusion of suppression effectiveness in fire line growth models is formulated as a system of differential equations. The model draws on earlier ideas using ellipses to model fire growth, particularly the head fire and flank fire rates of spread, combines this with recent studies of the effect of fire line on spread rate and appends a single equation for the increase of suppressed fire line with time. Representative parameter values are used to illustrate this way of describing the effect of fire suppression activities on the fire line and to develop criteria for the likely outcome of containment activities.
