Title: Deliverable D6.1-1-0020 SCHEDULE OF THE FUEL EDITOR PROJECT /
Language: English
Description: The Fuel Editor software is aimed at facilitating the dynamic construction of scenes representing vegetation, as “virtual fuel types”. Scenes of vegetation are built by assemblages of trees and shrubs and they are used as input data for the fire propagation models. These “virtual fuel types” could also be used to assess the effects of fire on the vegetation and the need for post fire salvage operations.

Title: D6.1-3 TECHNICAL ANALYSIS OF THE SOFTWARE /
Language: English
Description: The aim of the Work Package (WP) 6.1 “Design, development, test and deployment of a fuel editor” within the Fire Paradox-project is to develop software that generates vegetation scenes in two dimensions (2D) or three dimensions (3D) to be used as input data for fire behaviour models. The software to be developed will also be used to visualise effects of fire on virtual fuel types as well as to visualise the vegetation build up after fire occurrence. The software has to integrate current data processing procedures and needs to be compatible with both 2D and 3D fire behaviour models. This deliverable is devoted to the description of the architecture and technologies that will be used for developing the software. It is structured in three main parts: a summary of the main functionalities of the software is first presented; then, the software architecture is described and finally, technologies or technology families used for each component and their connections are explained.

Title: Deliverable D6.1-5 Fire Paradox Fuel Manager: User’s manual /
Language: English
Description: The FIRE PARADOX FUEL MANAGER is a computer software integrated in the data processing chain between the European data and knowledge base on fuels (EUROFORESTFUELS database) and the 3D physical-based fire propagation models. The scientific objective is the representation of vegetation scenes and their transformation into fuel complexes including all the necessary parameters to run a fire behaviour model. The technological objectives are to implement a user friendly platform to generate fuel complexes in 3D, to provide tools for managing the EUROFORESTFUELS database, to visualize fire effects on trees and simulate post fire vegetation successions. A survey of available simulation platform technologies has led us to join the CAPSIS project, dedicated to hosting a wide range of models for forest dynamics and stand growth. A new CAPSIS module – “FireParadox” – has been developed which implements data structure and functionalities of the FIRE PARADOX FUEL MANAGER. A 3D vegetation scenes’ editor has been implemented allowing interactive manipulative functionalities on vegetation scenes (e.g. zoom, rotation, etc) as well as on vegetation objects (selecting, adding, updating) through a graphical user interface. Several renderers are available to display 3D vegetation objects. Fire damage on vegetation objects have been mainly focused on fire-induced tree mortality. Several fire impacts on trees crown and trunk have been defined and can be visualized at the scene scale. Moreover, several tools are available to display information (descriptive statistics, indicators) on the vegetation scene content or on the current selection. Several creation modes of vegetation scenes are available including loading of a pre-existing inventory file or the automatic generation of a new scene respecting a set of constraints on species distribution. The application is connected through the Internet to the EUROFORESTFUELS database and manages the users rights. EUROFORESTFUELS database is currently hosted by P13-WLS servers in Switzerland and will be located in a near future on P05-EFI server in Finland becoming a facility of the FIREINTUITION platform. An export module has been developed to prepare the set of files necessary to run the fire propagation model. Export files describe the composition and the structure of the fuel complexes taking into account the physical properties of various components of the different vegetation layers (trees, shrubs, herbs and litter) composing the vegetation scene.

Title: D 6.2-3-18-1000 Comparison of contamination models /
Language: English
Description: In the Fire Paradox project, the objective of the work package 6.2 “Development of a technological platform for integrating the spatial and temporal mechanisms on a completely spatial fire growth tool” is to develop a software tool able to simulate the propagation of fires at a landscape scale showing, through successive contours drawn on a map, the dynamic evolution of fire spread in any environmental scenario. Different models and software tools have been proposed to simulate fire behaviour. This paper analyzes and reviews a selection of existing systems (in terms of simulation comparisons and quantitative analysis) in order to discuss and choose some modelling paradigms as bases for the new Fire Paradox propagation modelling software. Several analyzed models are based on too simplistic physical to be able to simulate the spread of fire across the landscape in a reasonable manner and spatially at high spatial resolution required for the scope of Fire Paradox. In particular they lack consideration of fire-wind feedbacks effects, which we consider mostly important. On the other hand, some tools are a rather complete physical description of the system (including convection effects), but they require (beside a huge use of computational resources) complicated setting of parameters and too detailed data inputs for the Fire Paradox aims. Our conclusion is that Fire Paradox simulator, compared to existing products, should be characterized by an intermediate level. The description of fuel remains a critical issue. We suggest that further investigations should be addressed to define fuel properties related to the combustion process separately from the convection and related propagation processes.

Title: D 6.3-5 Requirements for WAsP adaptation /
Language: English
Description: WAsP Engineering (WEng) offers a fast, basic wind flow model which can be used to provide most of the wind field predictions needed by the other parts of the Paradox fire model as currently envisaged. If Paradox wishes to provide ‘a European FARSITE’, then WEng is a good starting point. The FARSITE group is implementing a straightforward flow model (WindWizard) to generate input wind fields for their spread simulation, with no feedback from the fire to the wind. WEng has known limitations in complex terrain. A more advanced type of wind model might be necessary if these limitations are revealed to be significant. We can almost certainly provide such a model and drop it in to the Paradox system as a replacement if needed. In the meantime, we should devote some effort to evaluating the shortcomings of WEng in this respect, and comparing its output against other, more complex, flow models. If the simulations need to be run for low wind speed conditions, in which diurnal thermally-driven breezes are relatively important contributors to the predicted wind field, then we can use WEng in conjunction with another model to capture and predict these effects. This has been done before at Risø. So WEng seems an adequate first choice: one which can be extended and consolidated (even replaced) if necessary. Most of this work would fall within our existing experience and expertise. If the Paradox effort must provide a complete European alternative to the ongoing coupled fire-atmosphere modelling work at NCAR, then WEng cannot serve us. In that case, we must begin working with an atmosphere model capable of being coupled, which for us would represent a new research area rather than a re-application of existing technology. WEng cannot be used to model the two-way interaction between the fire and atmosphere (a so-called coupled model), since it is simply not designed to work with intense thermal updrafts. However, we think that we could develop a simpler, implicit treatment of the thermal effects. This would be applied as corrections to the fire-free wind field vectors. We imagine that it could allow us to emulate satisfactorily some important phenomena which coupled fire-atmosphere models have been able to exhibit, but without the complexity and performance costs which have prevented coupled models becoming operational tools.

Title: Fire Paradox Fuel Manager /
Language: English
Description: The Fire Paradox Fuel Manager is a computer software integrated in the data processing chain between the European data and knowledge base on fuels (Fire Paradox Fuel Database) and the 3D physical-based fire propagation models. From a fire manager's point of view, vegetation is not only a conglomerate of plants, but it is also combustible organic material that holds a potential fire risk. It is therefore of great interest to assess the effects of silvicultural measures and fuel treatments to appraise their efficiency on fire hazard reduction. Within the Fire Paradox project such a fuel and fire effects assessment system has been developed. The Fire Paradox Fuel Manager enables users to analyse the relationships between vegetation characteristics, fire behaviour and post-fire impact on vegetation. The Fire Paradox Fuel Manager is a key application in the fire modelling process with the following major objectives: (1) to generate vegetation scenes in 3D to be used as input data for fire behaviour modelling; (2) to visualize fire effects on shrubs and trees; (3) to simulate post fire vegetation succession coupled with a plant growth model. The software has been developed on the Capsis (Computer-aided projection of strategies in silviculture) platform for modelling forest dynamics and stand growth. Capsis is a tool for forestry researchers, forest managers and educators.
