Abstract

This paper presents an open-source computational tool that simulates the growth of fires which may occur in any region of Chile, and is also capable of estimating burn probability maps through an iterative and concatenated process of simulating spatially explicit fire ignition and fire growth scenarios. This tool, known as C2F+K, is based on the Cell2Fire simulator and KITRAL, the Chilean fire behaviour system. It incorporates new equations for the calculation of the rate of spread and the length-to-breadth ratio as a function of wind speed that are based on an elliptical shape model. C2F+K also includes a model of crown fire behaviour that is validated with numerical experiments. The system's performance is evaluated through comparisons with real and simulated wildfires using the KITRAL software. C2F+K features cross-platform compatibility and flexibility, allowing it to take advantage of parallel computing for fire growth modeling and the generation of risk maps.

Keywords: Burn probability, Fire growth simulation, Fire risk, Open-source software, Stochastic simulations, Fire management
