BehavePlus fire modeling system, version 4.0: User's Guide

Publications Posted on: August 01, 2018
The BehavePlus fire modeling system is a program for personal computers that is a collection of mathematical models that describe fire and the fire environment. It is a flexible system that produces tables, graphs, and simple diagrams. It can be used for a multitude of fire management applications including projecting the behavior of an ongoing fire, planning prescribed fire, and training.

Weather, fuels, and topography impede wildland fire spread in western US landscapes

Publications Posted on: August 30, 2016
As wildland fire activity continues to surge across the western US, it is increasingly important that we understand and quantify the environmental drivers of fire and how they vary across ecosystems. At daily to annual timescales, weather, fuels, and topography are known to influence characteristics such as area burned and fire severity.

Wildland fire as a self-regulating mechanism: The role of previous burns and weather in limiting fire progression

Publications Posted on: September 29, 2015
Theory suggests that natural fire regimes can result in landscapes that are both self-regulating and resilient to fire. For example, because fires consume fuel, they may create barriers to the spread of future fires, thereby regulating fire size. Top-down controls such as weather, however, can weaken this effect.

Mechanisms of fire spread research, Progress Report No. 2.

George Fahnestock's work (1960) on logging slash was a guide for establishing the experimental plots. The purposes of his study and the present one were different. Fahnestock was interested chiefly in comparing the influences of species, loading, and aging on burning slash. He was evaluating factors that influence the burning of natural beds of logging slash.

Beaufort scale of wind force as adapted for use on forested areas of the northern Rocky Mountains

Publications Posted on: August 12, 2015
The Beaufort scale of wind force, internationally employed by weather agencies, was not designed for use on mountainous and forested areas like those of the Rocky Mountains of northern Idaho and western Montana.

The potential and realized spread of wildfires across Canada

Publications Posted on: September 19, 2014
Given that they can burn for weeks or months, wildfires in temperate and boreal forests may become immense (eg., 100 - 04 km2). However, during the period within which a large fire is 'active', not all days experience weather that is conducive to fire spread; indeed most of the spread occurs on a small proportion (e.g., 1 - 15 days) of not necessarily consecutive days during the active period.

FlamMap

FlamMap is a fire behavior mapping and analysis program that computes potential fire behavior characteristics (spread rate, flame length, fireline intensity, etc.).

BehavePlus

Tools Posted on: August 05, 2014
The BehavePlus fire modeling system is a PC-based computer program that can be used for any fire management application that involves modeling fire behavior and fire effects. The system is composed of a collection of mathematical models that describe fire behavior, fire effects, and the fire environment.

Fire spread characteristics determined in the laboratory

Publications Posted on: January 07, 2013
Fuel beds of ponderosa pine needles and white pine needles were burned under controlled environmental conditions to determine the effects of fuel moisture and windspeed upon the rate of fire spread. Empirical formulas are presented to show the effect of these parameters. A discussion of rate of spread and some simple experiments show how fuel may be preheated before the fire reaches the fuel.

Estimation of wildfire size and risk changes due to fuels treatments

Publications Posted on: August 28, 2012
Human land use practices, altered climates, and shifting forest and fire management policies have increased the frequency of large wildfires several-fold. Mitigation of potential fire behaviour and fire severity have increasingly been attempted through pre-fire alteration of wildland fuels using mechanical treatments and prescribed fires.
