BehavePlus Fire Modeling System

What's New?

(Subscribe to Fire Behavior)

BehavePlus v6 Beta has been released!

BehavePlus version 6 Beta is available for download, testing, and use. The program can be downloaded from the Software / Manuals page. There were many changes to the program, which are outlined in the Change Log [PDF]. One of the biggest changes is to calculating surface fire behavior (SURFACE). Lessons have been created to guide you through the changes, and they can be downloaded as a zip file.

The BehavePlus fire modeling system is a Windows® based computer program that can be used for any fire management application that involves modeling fire behavior and some fire effects. The system is composed of a collection of mathematical models that describe fire behavior and the fire environment. The program simulates rate of fire spread, spotting distance, scorch height, tree mortality, fuel moisture, wind adjustment factor, as well as other variables; so it is used to predict fire behavior in multiple situations. More information can be found in the following paper:

Andrews, Patricia L. 2014. Current status and future needs of the BehavePlus Fire Modeling System. International Journal of Wildland Fire 23(1):21-33.

Successful application of BehavePlus depends upon knowledgeable user decisions. To effectively use BehavePlus in fire modeling, users must have enough fire experience and training in fire behavior models to recognize whether input values are appropriate, outputs are reasonable, and which adjustments are needed to correctly model the fire behavior.
