OBJECTIVES

The management of wildland/urban interfaces is one of the key-points of wildland fire prevention policy and land management in Mediterranean regions. Foresters, fire-fighters and engineering offices need methods and tools: to assess the fire risk for exposed targets (people, structures and buildings) on these interfaces, and to test the preventive efficiency of the wildland fuel reduction. The technological objective of Fire Star is to provide methods and tools to the end-users through a decision support system. Researchers and end-users will jointly define the functionalities of the system. Researchers of the Consortium will also pursue the following main scientific objectives: to improve the methods of wildland fuel description and to develop Mediterranean models, to enhance the predictive ability of the wildland fire behaviour model, and to improve the knowledge of wildland fire effects on the exposed targets.

DESCRIPTION OF WORK

Fire Star consortium will specify end -users' needs and define with them the problems to be solved (type of questions, characteristics of wildland fuel and target on the interface). Modellers will improve the physics of the model of wildland fire behaviour with experimentalists. They will extend the predictive ability of the existing model to wildland-urban interface scales, and develop a 3D version of the model. They will investigate the effects of wildland fire onto the targets through the coupling of the wildland fire model and the heat transfer to the target. Specialists of structure fires will provide data related to people's tenability and to material responses to heat supply. The modellers will provide the simulations of wildland fire behaviour and effects matching the scenarios defined with the end-users. Experimentalists will improve the knowledge of some basic wildland fire mechanisms and properties. For this, they will adapt some advanced optical measurement methods to the particular conditions of wildland fires. The modellers will inc lude these improvements into the model of wildland fire behaviour. They will also provide data for its validation (laboratory tests and field fire experiments). Experimentalists will determine the thermal-physical characteristics of wildland fuel particles and will describe and model the spatial structure of the wildland fuel (input of the model of wildland fire behaviour). It will be essential to provide the spatial distribution of the different fuel families for a given ecosystem from a set of "simple" field measurements performed on the vegetation. Computer scientists will design and develop the decision support system. They will also manage a network of servers and computers to enable an efficient exchange of data, methods and models between the partners . The researchers will provide pedagogical supports explaining how to use the decision support system.
