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.

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 Fire Modelling written by G. Cox and published by . This book was released on 2004 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Digest explains the methodologies being used for the computer simulation of fire. It focuses on models of the fire itself: the essentially gas phase phenomenon at the heart of any fire simulation. Numerical modelling has become increasingly attractive for those wishing to fully exploit the freedoms to achieve safe, cost effective design offered by performance based regulation. This new edition of Digest 367 supersedes the version published in 1991. It explains fire growth and spread, and the two basic types of computer simulation methodologies. These are the zonal models, and the more universal field models that use the specialist discipline of computational fluid dynamics. Two types of field model are described which employ alternative approaches using Reynolds Averaged and Large Eddy methodologies to capture the influences of turbulence. An example shows the BRE CRISP model applied to the problem of smoke spread through a two storey theatre and the evacuation of the occupants.

Available in PDF, EPUB and Kindle. Book excerpt: Computer simulation proves to be a valuable tool for the analysis and prediction of compartment fires. With the proper understanding and software, fire safety professionals can use modeling tools and methods to find answers to many critical questions relating to the prevention, investigation, and reconstruction of compartment fires. Thoroughly updated and revised, An Introduction to Mathematical Fire Modeling, Second Edition introduces the concepts, software, and techniques of computer-aided mathematical modeling and the software for the analysis and prediction of a variety of compartment fires. Beginning with basic compartment fire theory, the author develops a simple mathematical model that provides an engineering approximation of the time-varying conditions created by fires in an enclosure that may be subject to hot-layer vents. This is the first book focused on the deterministic computer modeling of compartment fires, and the FIRM model presented is the first fire model to be documented, validated, verified, and evaluated according to ASTM guidelines. The text includes detailed information on the use of the QBASIC software provided on an enclosed CD-ROM.

Book excerpt: This Digest introduces the concept of computer modelling of fires. Modelling techniques have long played a part in fire simulation but the development of powerful computers has led to rapid progress in numerical fire modelling. Such modelling offers those involved in building control and design far-reaching possibilities for the prediction of the consequences of fire and planning of fire protection strategies. Growth and spread of fire are explained and the two basic types of theoretical computer models are described: zone models which are related closely to established traditional methods and field models which exploit new techniques to study smoke movement.

Available in PDF, EPUB and Kindle. Book excerpt: The Ecological Importance of High-Severity Fires, presents information on the current paradigm shift in the way people think about wildfire and ecosystems. While much of the current forest management in fire-adapted ecosystems, especially forests, is focused on fire prevention and suppression, little has been reported on the ecological role of fire, and nothing has been presented on the importance of high-severity fire with regards to the maintenance of native biodiversity and fire-dependent ecosystems and species. This text fills that void, providing a comprehensive reference for documenting and synthesizing fire's ecological role. Offers the first reference written on mixed- and high-severity fires and their relevance for biodiversity Contains a broad synthesis of the ecology of mixed- and high-severity fires covering such topics as vegetation, birds, mammals, insects, aquatics, and management actions Explores the conservation vs. public controversy issues around megafires in a rapidly warming world

Available in PDF, EPUB and Kindle. Book excerpt: Retrospectives on Public Finance contains original analyses by internationally recognized public finance scholars, including Carl Sumner Shoup, one of the discipline's most famous practitioners. Shoup, along with Richard Musgrave and his students, pioneered the "prescriptive" or "political economy school" of public finance known for its hands-on approach and its commitment to applying theory to real world problems. Each contributor provides a retrospective on Shoup's various contributions to the field, reviewing the literature and assessing its relevance to current problems in public finance theory and policy. The essays highlight and analyze fiscal theory and public policy developments from the 1930s to the present in four areas: the Shoup tax missions to Japan, Venezuela, and Liberia; the tax mix; the expenditure mix; and macro public finance.
