Standard fire behavior fuel models: a comprehensive set for use with Rothermel's surface fire spread model

Publications Posted on: August 01, 2018
This report describes a new set of standard fire behavior fuel models for use with Rothermel's surface fire spread model and the relationship of the new set to the original set of 13 fire behavior fuel models. To assist with transition to using the new fuel models, a fuel model selection guide, fuel model crosswalk, and set of fuel model photos are provided.

Why and where high-severity fire occurs

Science Spotlights Posted on: April 26, 2018
The need to better understand factors controlling fire severity are invoked by concerns about public safety, infrastructure, critical wildlife habitat, watershed health, and successional trajectories. Such concerns are heightened in forests with a legacy of past logging and fire exclusion, where significant shifts in ecosystem composition, structure, and function have triggered fuel conditions at greater risk for high-severity fire.  

Selection of fire spread model for Russian fire behavior prediction system

Publications Posted on: October 07, 2011
Mathematical modeling of fire behavior prediction is only possible if the models are supplied with an information database that provides spatially explicit input parameters for modeled area. Mathematical models can be of three kinds: 1) physical; 2) empirical; and 3) quasi-empirical (Sullivan, 2009).

Retrospective fire modeling: Quantifying the impacts of fire suppression

Publications Posted on: April 14, 2010
Land management agencies need to understand and monitor the consequences of their fire suppression decisions. We 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.

BEHAVE: fire behavior prediction and fuel modeling system--FUEL subsystem

Publications Posted on: April 05, 2008
This manual documents the fuel modeling procedures of BEHAVE--a state-of-the-art wildland fire behavior prediction system. Described are procedures for collecting fuel data, using the data with the program, and testing and adjusting the fuel model.

BEHAVE: fire behavior prediction and fuel modeling system-BURN Subsystem, part 1

Publications Posted on: April 05, 2008
Describes BURN Subsystem, Part 1, the operational fire behavior prediction subsystem of the BEHAVE fire behavior prediction and fuel modeling system. The manual covers operation of the computer program, assumptions of the mathematical models used in the calculations, and application of the predictions.

Nomographs for estimating surface fire behavior characteristics

Publications Posted on: May 02, 2007
A complete set of nomographs for estimating surface fire rate of spread and flame length for the original 13 and new 40 fire behavior fuel models is presented. The nomographs allow calculation of spread rate and flame length for wind in any direction with respect to slope and allow for nonheading spread directions. Basic instructions for use are included.

How to predict the spread and intensity of forest and range fires

Publications Posted on: October 06, 2006
This manual documents procedures for estimating the rate of forward spread, intensity, flame length, and size of fires burning in forests and rangelands. Contains instructions for obtaining fuel and weather data, calculating fire behavior, and interpreting the results for application to actual fire problems.
