Modelling fire fighters actions in a forest fire simulation algorithm

Abstract : We introduce in this paper an algorithm for forest fire spread modelling which involves actions carried on by fire fighters. The calculation of fire propagation is performed on a graph mapped onto a 2-D grid of cells representing the landscape. The propagating vertices are either centers or corners of the cells whereas vertices belonging to the fire final contour can be located in any points. The fire rate of spread along the different edges of the graph are calculated in 3-D cells approximating the relief. The corresponding calculations are made with the proviso that starting from a given ignition point, the fire evolves to an elliptic shape. The global fire propagation is then obtained by means of the Dijkstra's shortest path algorithm. We conclude on the fact that taking into account fire fighters actions is indispensable when forest fire simulation is used in operational frameworks.
