Download or read book Mapping Wildfire Susceptibility with the BURN P3 Simulation Model written by Marc-André Parisien and published by . This book was released on 2005 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: Resource management in fire-dominated ecosystems requires an understanding of the probability of wildfire occurring & spreading at different points in a landscape. This report describes an approach to evaluating wildfire susceptibility, or burn probability, for fire-prone landscapes such as the boreal forest of North America. The approach involves use of the BURN-P3 (probability, prediction, & planning) landscape-level simulation model, which combines deterministic fire growth based on the Canadian Fire Behaviour Prediction System and spatial data for forest fuels & topography with probabilistic fire ignitions & spread events derived from historical fire & weather data. A case study of the application of BURN-P3 is undertaken for a boreal mixedwood area of central Saskatchewan. The results presented highlight the importance of landscape features to wildfire susceptibility and indicate whether assessments based solely on stand-level characteristics are adequate.
Download or read book Modelling Monitoring and Management of Forest Fires written by J. de las Heras and published by WIT Press. This book was released on 2008-08-26 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: At present there is insufficient knowledge of the behavior of fires and how they propagate. This lack of information makes it very hard to control these phenomena and is one of the biggest obstacles to the development of a reliable decision support system. Public concern regarding this topic is increasing as uncontrolled fires may lead to major ecological disasters, and usually result in negative economic and health implications for the region. Containing papers presented at the First International Conference on Modelling, Monitoring and Management of Forest Fires, this book addresses the latest research and applications of available computational tools to analyse and predict the spread of forest fires in order to prevent or reduce major loss of life and property as well as damage to the environment. Such tools must be able to take into consideration a large number of different parameters. The book thus deals with all aspects of forest fires, from fire propagation in different scenarios to the optimum strategies for fire-fighting. It also covers issues related to economic, ecological, social and health effects. Featured topics include: Computer Models for Fire Propagation; Risk and Vulnerability Assessment; Fire Combustion Models; Computational Methods and Experiments; Case Studies; Emergency Response Systems; Optimization Models for Fire Mitigation; Environmental Impact Models; Air Pollution and Health Risk; Interaction between Meteorological and Forest Fires Models; Economic Impact Models; Forest Material Characterisation; Eco Remediation Models; Decision Support Systems; Monitoring Systems and Data Acquisition and Analysis.
Download or read book Mapping Wildfire Hazards and Risks written by R Neil Sampson and published by CRC Press. This book was released on 2000-10-10 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: Develop accurate computer models to determine wildfire risks and controlled-burn benefits! Although scientists now recognize that fire is essential to many ecosystems, the ecological and political issues of managing wildfire continue to be vexing. Mapping Wildfire Hazards and Risks offers multiple perspectives on using a Geographic Information System (GIS) for more effective wildfire management. This innovative technology is the ideal tool to organize and display all the information available, so authorities can make informed judgments based on all the facts. Because the authors are not merely theorizing but discussing the GIS they are actually building and using, Mapping Wildfire Hazards and Risks offers practical ideas and perspectives, including: specific information on the modeling approach and kinds of data utilized valuable discussions of the social and environmental factors included in the model techniques for predicting the effects of wildfire on neighborhoods, soil erosion, sedimentation, and air quality predictions of long-term ecosystem recovery given wildfires of different sizes and intensities maps, charts, tables, and formulas to make the process of building a GIS understandable and accessible Mapping Wildfire Hazards and Risks is a compilation of the ideas of federal and state agencies, universities, and non-governmental organizations on how to rank and prioritize forested watershed areas that are in need of prescribed fire. This book provides the essential information for deciding how to set priorities for wildfire management that might reduce risks or lower future damages.

Download or read book Retrospective Fire Modeling written by Brett H. Davis and published by DIANE Publishing. This book was released on 2011 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a print on demand edition of a hard to find publication. Land management agencies (LMA) need to understand and monitor the consequences of their fire suppression decisions. The authors developed a framework for retrospective fire behavior modeling and impact assessment to determine where ignitions would have spread had they not been suppressed, and to assess the cumulative effects that would have resulted. This guidebook is used for applying this methodology and is for those interested in quantifying the impacts of fire suppression. Land managers who use this methodology can track the cumulative effects of suppression, frame future suppression decisions and cost-benefit analyses in the context of past experiences, and communicate tradeoffs to the public, non-gov. organ., and LMA.

Download or read book Development and Structure of Prometheus written by Cordy Tymstra and published by . This book was released on 2009 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Accurate, high-resolution fire behavior prediction is a critical component of fire management decision-making before and during fires. Prometheus is a deterministic fire growth simulation model that was developed to help fire managers to understand the probable consequences of their decisions. It uses spatial input data on topography (slope, aspect, and elevation), fuel types, and weather to simulate fire growth by applying Huygens principle of wave propagation to the rate-of-spread predictions from the Canadian Forest Fire Behavior Prediction System of the Canadian Forest Fire Danger Rating System. This approach produces detailed fire perimeters at user-specified display time step intervals. Each active vertex along the perimeter has corresponding fire behavior output. Exported fire perimeters are compatible with geographic information systems. Additionally, three interpolation techniques are available to produce optional raster fire behavior outputs. This report documents the structure of the Prometheus model and an assessment of its performance. The report includes a general discussion of approaches to the modeling of fire growth simulation and explains the vector propagation technique used in Prometheus. The limitations and assumptions of applying the model, as well as the most appropriate directions for future research, are also discussed.

Download or read book Fire Science written by Francisco Castro Rego and published by Springer Nature. This book was released on 2021-09-24 with total page 670 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook provides students and academics with a conceptual understanding of fire behavior and fire effects on people and ecosystems to support effective integrated fire management. Through case studies, interactive spreadsheets programmed with equations and graphics, and clear explanations, the book provides undergraduate, graduate, and professional readers with a straightforward learning path. The authors draw from years of experience in successfully teaching fundamental concepts and applications, synthesizing cutting-edge science, and applying lessons learned from fire practitioners. We discuss fire as part of environmental and human health. Our process-based, comprehensive, and quantitative approach encompasses combustion and heat transfer, and fire effects on people, plants, soils, and animals in forest, grassland, and woodland ecosystems from around the Earth. Case studies and examples link fundamental concepts to local, landscape, and global fire implications, including social-ecological systems. Globally, fire science and integrated fire management have made major strides in the last few decades. Society faces numerous fire-related challenges, including the increasing occurrence of large fires that threaten people and property, smoke that poses a health hazard, and lengthening fire seasons worldwide. Fires are useful to suppress fires, conserve wildlife and habitat, enhance livestock grazing, manage fuels, and in ecological restoration. Understanding fire science is critical to forecasting the implication of global change for fires and their effects. Increasing the positive effects of fire (fuels reduction, enhanced habitat for many plants and animals, ecosystem services increased) while reducing the negative impacts of fires (loss of human lives, smoke and carbon emissions that threaten health, etc.) is part of making fires good servants rather than bad masters.
Download or read book Retrospective Fire Modeling Quantifying the Impacts of Fire Supression written by Brett Davis and published by CreateSpace. This book was released on 2012-10-23 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: When wildfires are suppressed, opportunities are foregone to create fuel breaks, reduce fire regime departures, and decrease future extreme fire behavior by modifying fuels. To our knowledge, no one has yet attempted to systematically quantify these foregone opportunities. This general technical report describes a methodology to measure the cumulative impacts of suppression over time by modeling the spread of ignitions that were suppressed. We illustrate a set of analysis steps to simulate where ignitions would have spread had they not been suppressed and to assess the cumulative effects that would have resulted from those fires. The quantification of these effects will help land managers improve the prioritization and planning of fuels treatments and help inform decisions about the suppression of future ignitions. In its simplest application, the methodology compares two landscapes: the realized landscape vs. a hypothetical landscape. As used throughout this guidebook, a "landscape" refers mainly to the biophysical characteristics of the study area such as vegetation and fuel conditions and potential fire behavior. The realized landscape is the landscape that resulted due to the fire management strategies actually implemented; this is typically the current landscape. The hypothetical landscape is the landscape that would have resulted if different fire management strategies had been chosen (e.g., if one or more suppressed ignitions had been allowed to burn freely). While the examples in this guidebook compare only two landscapes, any number of landscapes could be compared. A case study examines what conditions might have resulted if lightning-ignited fires were not suppressed in the South Fork Merced watershed of Yosemite National Park. The retrospective modeling process requires modeling the spread of ignitions that were suppressed, updating the fuels data to reflect that modeled fire, and repeating this process to account for all the ignitions of interest throughout the simulation period; this results in the hypothetical landscape. Once the modeling cycles are complete, the final step involves assessing the impacts of fire suppression by comparing the hypothetical and realized landscapes using various metrics depending on need and purpose. For example, the hypothetical and realized landscapes might be compared in terms of potential fire behavior (i.e., flame length or crowning potential). This document is a guidebook in that it provides a moderate level of detail for implementing the methodology and uses a case study to illustrate some procedures. However, it does not provide step-by-step instructions. Furthermore, inputs and parameters used in the case study are for illustration and should not be applied uncritically to other situations. Occasionally, specific tips on how best to accomplish the required steps are offered, but this guidebook is not intended to be a tutorial for specific modeling software, nor is it a text on fire behavior, ecology, or management. To implement the methodology here, the user must have some basic skill sets. The most important skills include basic Geographic Information System (GIS) data manipulation and analysis, experience with fire growth modeling software such as FARSITE (Finney 1998), and familiarity with fire management terminology. Other useful skills include familiarity with other fire modeling software such as FlamMap (Finney 2006) and FireFamilyPlus (FFP; Bradshaw and McCormick 2000), and knowledge of fuels characterization, fire weather analysis, fire behavior, fire ecology, and fire management.
Download or read book Assessing Potential Biophysical and Socioeconomic Impacts of Climate Change on Forest based Communities written by T. B. Williamson and published by . This book was released on 2008 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents methods for assessing the potential biophysical and socioeconomic impacts of climate change at scales relevant to forest-based communities. The methods are tested and demonstrated by estimating such impacts for the community of Vanderhoof, British Columbia. First, spatially referenced climate histories and climate scenarios are developed for a 200 km 200 km study area surrounding Vanderhoof. Second, these climate data are linked to new models and methods for projecting changes in productivity, species, and wildfire risk under conditions of climate change. Third, methods for linking changes in productivity to potential changes in harvest rate and then to potential changes in aggregate household income are developed and applied. Finally, an approach for linking, presenting, and comparing the results from the various methods is presented. This approach takes account of both climate change and parallel socioeconomic changes occurring in a communitys external environment and acknowledges the inherent uncertainty in climate and socioeconomic scenarios. The approach is based on the development of multitiered scenario radar maps, which are then compressed into a single radar map providing a concise summary of potential climate impacts on a particular community. The assessment of community vulnerability tends to be specific to a particular location. Nevertheless, the Vanderhoof case study highlights areas where forest-based communities may be uniquely exposed, sensitive, and therefore potentially vulnerable to the impacts of climate change. Climate change may increase fire risk in forests surrounding communities. It is also likely to affect timber supplies (positively, negatively, or both), thereby causing changes in local economic activity and increasing instability and uncertainty. Moreover, these responses may be variable and nonlinear over time. The Vanderhoof experience with the mountain pine beetle (Dendroctonus ponderosae Hopkins) shows that climate change has the potential to affect natural capital near other forestbased communities. Reduction of the natural capital asset base supporting any community will ultimately result in negative socioeconomic impacts. Governments (municipal, provincial, and federal) could use the approaches described here to identify locations where natural capital is at greatest risk. This information is needed to develop strategies for either protecting existing natural capital, replacing lost capital, or transforming exposed natural capital to alternative types of assets that are less sensitive to climate change.
