Assessing Crown Fire Potential by Linking Models of Surface and Crown Fire Behavior
Author: Joe H. Scott
Publisher:
ISBN:
Category : Fire risk assessment
Languages : en
Pages : 68
Book Description
Fire managers are increasingly concerned about the threat of crown fires, yet only now are quantitative methods for assessing crown fire hazard being developed. Links among existing mathematical models of fire behavior are used to develop two indices of crown fire hazard-the Torching Index and Crowning Index. These indices can be used to ordinate different forest stands by their relative susceptibility to crown fire and to compare the effectiveness of crown fire mitigation treatments. The coupled model was used to simulate the wide range of fire behavior possible in a forest stand, from a low-intensity surface fire to a high-intensity active crown fire, for the purpose of comparing potential fire behavior. The hazard indices and behavior simulations incorporate the effects of surface fuel characteristics, dead and live fuel moistures (surface and crown), slope steepness, canopy base height, canopy bulk density, and wind reduction by the canopy. Example simulations are for western Montana Pinus ponderosa and Pinus contorta stands. Although some of the models presented here have had limited testing or restricted geographic applicability, the concepts will apply to models for other regions and new models with greater geographic applicability.

FARSITE, Fire Area Simulator--model Development and Evaluation
Author: Mark A. Finney
Publisher:
ISBN:
Category : FARSITE (Computer file)
Languages : en
Pages : 52
Book Description
A computer simulation model, FARSITE, includes existing fire behavior models for surface, crown, spotting, point-source fire acceleration, and fuel moisture. The model's components and assumptions are documented. Simulations were run for simple conditions that illustrate the effect of individual fire behavior models on two-dimensional fire growth.

Forest Fires
Author: Philip Nori Omi
Publisher: Bloomsbury Publishing USA
ISBN: 1851094431
Category : Science
Languages : en
Pages : 366
Book Description
From killer fires to ecosystem rehabilitation, an exhaustive survey exploring the ecological, social, and economic consequences of managing fires in U.S. wildland areas. Fire management involves protecting natural resources from fire but also using controlled burning for land management purposes. Who are the stewards of land management and the researchers who devote their entire careers studying fire? How are ecosystems restored after major fires? What are the economic ramifications and what assessment tools are available? Forest Fires: A Reference Handbook explores the historical, ecological, economic, and social dimensions of wildland combustion and their impacts in North America. Explaining how legislation and public perception have been shaped by historic fires and fire seasons, particular emphasis is placed on the summer of 2000 as a way of understanding and managing future fires.
