Book Synopsis Diurnal Variation in the Fine Fuel Moisture Code by : B. D. Lawson
Download or read book Diurnal Variation in the Fine Fuel Moisture Code written by B. D. Lawson and published by Canadian Forest Service. This book was released on 1996 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forest fire managers must be able to predict the normal variation in fine fuel moisture around the clock, since it is a critical factor that affects the behaviour and control of wildfires and prescribed burns. The Canadian Forest Fire Weather Index System contains a Fine Fuel Moisture Code (FFMC) that produces a standard daily index of expected fine fuel moisture at the mid-afternoon peak of fire danger, but does not output normal diurnal variation in FFMC. This paper documents the development and updating of an earlier model of diurnal variation in FFMC, presents the underlying equations and a lookup table, and announces the availability of a computer program version of the model for various user applications.
Book Synopsis Modeling Moisture Content of Fine Dead Wildland Fuels by : Richard C. Rothermel
Download or read book Modeling Moisture Content of Fine Dead Wildland Fuels written by Richard C. Rothermel and published by . This book was released on 1986 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Describes a model for predicting moisture content of fine fuels for use with the BEHAVE fire behavior and fuel modeling system. The model is intended to meet the need for more accurate predictions of fine fuel moisture, particularly in northern conifer stands and on days following rain. The model is based on the Canadian Fine Fuel Moisture Code (FFMC), modified to account for solar heating of fuels and to predict diurnal trends in fine fuel moisture. The model may be initiated without extensive data on prior weather. When compared to the FFMC and the fire behavior officers' procedures, the new model gave consistently better predictions over the complete range of fuel conditions.

Book Synopsis Wildland Fires and Air Pollution by : Andrzej Bytnerowicz
Download or read book Wildland Fires and Air Pollution written by Andrzej Bytnerowicz and published by Elsevier. This book was released on 2009 with total page 688 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wildland fires are one of the most devastating and terrifying forces of nature. While their effects are mostly destructive they also help with regeneration of forests and other ecosystems. Low-intensity fires clear accumulating biomass reducing risk of catastrophic crown fires and can be used as an effective management tool. This book presents current understanding of wildland fires and air quality as well as their effects on human health, forests and other ecosystems. in the first section of the book the basics of wildland fires and resulting emissions are presented from the perspective of changing global climate, air quality impairment and effects on environmental and human health and security. in the second section, effects of wildland fires on air quality, visibility and human health in various regions of the Earth are discussed. The third section of the book deals with complex issues of the ecological impacts of fires and air pollution in forests and chaparral in North America. The fourth section discusses various management issues facing land and fire managers which are related to wildfires, use of prescribed fires, and air quality. This section also presents various modeling systems used for describing fire dangers and behavior as well as smoke and air pollution predictions applied in the risk assessment analysis. The book concludes with a series of expert recommendations for wildland fire and atmospheric research.
Book Synopsis Modelling, Monitoring and Management of Forest Fires by : J. de las Heras
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.

Book Synopsis Field Guide to the Canadian Forest Fire Behaviour Prediction (FBP) System by : Stephen William Taylor
Download or read book Field Guide to the Canadian Forest Fire Behaviour Prediction (FBP) System written by Stephen William Taylor and published by University of Washington Press. This book was released on 1997 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Canadian Forest Fire Behaviour System is a systematic methodfor assessing wildland fore behaviour potential. The guide provides a simplified version of the system, presented in tabular format. It was prepared to assist staff in making first approximations of FBP system outputs when computer-based applications arenot available. Quantitative estimates of head fire spread rate, fire intensity, type of fire, and elliptical fire area, perimeter, and perimeter growth rate are provided for sixteen discrete fuel types within five broad groupings (coniferous, deciduous, and mixedwood forests, logging slash, and hrass), covering mostof the major forest fuel types found in Canada. The FBP system is intended to supplement the experience and judgment of fire managers.

Book Synopsis Canadian Forest Fire Behavior Prediction (FBP) System by : Kelvin G. Hirsch
Download or read book Canadian Forest Fire Behavior Prediction (FBP) System written by Kelvin G. Hirsch and published by UBC Press. This book was released on 1996 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Canadian Forest Fire Behaviour Prediction (FBP) System provides a systematic method of assessing fire behaviour. The FBP System has 14 primary inputs that can be divided into 5 general categories: fuels, weather, topography, foliar moisture content, and type and duration of prediction. In the FBP System these inputs are used to mathematically develop 4 primary and 11 secondary outputs. Primary outputs are generally based on a fire intensity equation, and secondary outputs are calculated using a simple elliptical fire growth model. This publication provides diagrams, examples, and exercises that explain the FBP System in a user-oriented manner. This guideline delineates the interpretation of the FBP System's inputs and outputs and details how the predictions are derived.
