Over the last few decades, considerable efforts have been focused on developing and implementing statistical and physics-based models to account for the interactions between fire, vegetation, and the atmosphere. These models have led to a better understanding of the dynamics of fire spread in a landscape and are continuing to contribute to the state of art of wildfire science. However, despite considerable progress in modeling fire behavior, wildfires occur in complex environments where multiple parameters and physical processes interact to influence its behaviour at a variety of spatial and temporal scales. Despite the wide use of these models, many have experienced some limitations. The main problem today is the existence of high intensity fire events, that are very difficult to control and can overwhelm suppression capabilities. It was reported by scientists that only 5% of these past years forest fires caused the most important damages. These so-called extreme fires seem to become a new standard. Thus, wildfires can still create unexpected scenarios for emergency services during real situations and result in significant injury, even fatalities, in addition to the numerous socioeconomic and the irreversible ecological impacts. Wildfires in wildland-urban interface communities have also rapidly grown in occurrence and strength over the past few decades due to the growing pace of urbanization and landscape transformation. Recently, using data assimilation and deep learning techniques to better predict wildfire behavior has aroused considerable interest. These emerging approaches coupled to standard models seem very promising. This special event offers an opportunity for those involved in fire safety science and wildfire / wildland urban interface fire behavior to present their work. The target audiences for this program are graduate students, post-doctoral fellows, and researchers and engineers, engaged in fire science and fire safety research programs. The adopted viewpoint in the program is primarily (but not exclusively) engineering based. The objectives are to expose a broad range of advanced topics with a mix between fundamental aspects (underlying physical and chemical mechanisms) and the current challenges related to the mitigation of the negative impacts of these extreme fires. Submissions are encouraged on, but not limited to, the following topics:

Fuel flammability

Fire spreading

Fire dynamics

Fire suppression

Wildland fires and large outdoor fires

Enclosure fire dynamics

Wildfire risk assessment and management

Fire risk analysis and fire safety design

Wildland Urban Interface

Human evacuation and behavior

Environmental impacts of fire, sustainability

CFD simulation and modeling

AI / Deep Learning and/or data assimilation

Biography

Dr. Sofiane MERADJI Holder of a PhD in Computational Fluid Mechanics, obtained at the University of Aix-Marseille II in 1999, I started my research activity around the theme of forest fires, in 2006, during the European project FIRE PARADOX. Since 2010, I am a Research Engineer in Scientific Computing at the University of Toulon, in a laboratory of Applied Mathematics and Computer Science. My research focuses on the fire physics and tools development on HPC architectures.

Dr. Jean-Louis ROSSI (h-index : 15 ; i10-index : 17) is an Associate Professor (HDR) at the University of Corsica, France, where he got his PhD (1996). Prior to entering the field of wildfires, he worked in the area of modeling underwater sound scattering phenomena. His three main research topics are: 1) Development of a physical simplified surface fire spread model. 2) Development of models of radiant heat from shrub. 3) Development of safety distance models to address firefighter safety zones. The motivation of his current work is to develop better tools for operational applications. For instance, these tools could be used when addressing fire management, such as defining fuelbreak areas and firefighter safety zones at field scale. From 2018 is a part of the UNDRR international expert advisory group (E-STAG) as a Forest Fire expert.

Dr. Thierry MARCELLI is an assistant professor at the University of Corsica, France, where he got his PhD in 2002. He is teaching fluid mechanics and energetics at the University Institute of Technology in the Civil Engineering Department. Since 2002, he has been working on wildland fire behavior thanks to a simplified approach and a multiphase formulation. Since January 2020, he has been the co-manager of the GOLIAT project which is devoted to provide operational tools for fire-fighters and forest managers. This project is funded by the "Collectivité de Corse" and the French State (CPER: 40031).
