Fire Spread

Abstract
A new model for predicting fire propagation in homogeneous environments,
based on the transfer of a fractional burned area, is introduced in this paper. A
particular type of discrete dynamical system, called a hexagonal bidimensional
cellular automaton, is used in order to design the model. The simulations
obtained are found to be in agreement with the experience of fire spreading in
real forests.
Keywords: fire spreading, hexagonal cellular automata, mathematical
modelling.
1 Introduction
As is well-known, forest fires is one of the major ecological agents in forest
since they alter the structure and composition of forest and adversely affect
human health and the supply of goods and services on which communities
depend. Consequently, the study of forest fires have received increased public
attention by the scientific community. Specifically, several mathematical models
have been appeared in the literature in order to study the spreading of forest fire
fronts. The efforts to model the growth of the fire front by means of
mathematical models can be classified according to two approaches: vector
models and cellular automata models. Vector models assume that the fire front
spreads according to a well-defined growth law, and take a standard geometrical
shape (see, for example, Vakalis et al. [6]). On the other hand, several types of
cellular automata models for fire spreading have been introduced in the literature
(see Karafyllidis [1, 2]).
Keywords

modelling.
