Un Réseau de Petit Monde local à sites pondérés pour les feux de forêts

A two-dimensional weighed-site model based on the Small World Network is proposed to study fire spread through homogeneous and heterogeneous media. It combines the regular network properties for the whole system with the local Small World properties. First validated with various fire conditions for homogeneous media, it is then applied to heterogeneous media to illustrate its ability to provide realistic fire patterns. It is found that the density of active sites is a good measure of the Small World effect. To cite this article: B. Porterie et al., C. R. Physique 6 (2005).
