Some basic fire bahavior phenomena are described in terms of analytical solutions to simple physical models for the heating of unburned fuel to ignition temperature by radiation from the combustion region. The most interesting result is a model for the intrinsic acceleration experienced by a point fire during its early growth stage, which relies on the flame front being nonplanar. From this model it is possible to obtain an estimate of the lag time from ignition to steady-state spreading.

Plant epidemiologists have long been concerned with the patchy nature of plant disease epidemics. This paper presents a new analytical model for patchy plant epidemics (and patchy dynamics in general), using a second-order approximation to capture the spatial dynamics in terms of the densities and s
## Abstract The three basic modelling approaches used to explain forest fire behaviour are theoretically, laboratory or empirically based. Results of all three approaches are reviewed, but it is noted that only the laboratoryβ and empirically based models have led to forecasting techniques that are
An unsteady multidimensional model is reported with the objective of studying wild5res. The present work aims to validate the modelling assumptions against reported experiments of a lab-scale line 5re through a vegetation fuel bed. In this model the fuel bed is assumed to be a porous medium with a r
