Description

The BEHAVE fire behavior prediction and fuel modeling system is a set of interactive computer programs. BEHAVE provides mathematical prediction models in one easy-to-use package. This paper describes prediction capabilities that have been added to the system. Since 1984, BEHAVE has been used by land managers for a variety of fire management needs. A user can tailor predictions to specific needs based on the resolution of the input and interpretation of the output. For example, windspeed might be measured on site for real-time prediction of wildfire behavior. On the other hand, windspeed can be assigned a range of values in order to make assessments for planning purposes. Example uses of BEHAVE predictions are determining appropriate suppression action, predicting the growth of a wilderness fire, prescribed fire planning, setting dispatch levels, and after-the-fact predictions for an investigation. This paper is the third in a series of papers that describe the BEHAVE system. Burgan and Rothermel (1984) described the FUEL subsystem of BEHAVE, used for designing custom fuel models. Andrews (1986) described the initial BURN subsystem, the operational fire behavior prediction part of BEHAVE. This paper covers additions that have been made to the BURN subsystem. Part 1 of the BURN manual described the FIRE1 program. This paper is Part 2 of the BURN manual and describes additions to the FIRE1 program and the new FIRE2 program. The information in Part 1 is still valid. Worksheets for all modules in the FIRE1 and FIRE2 programs are in this manual (appendix B). We assume that you are familiar with BEHAVE, specifically with the material in Part 1 of the BURN manual. References will be made to that paper (Andrews 1986) by page number (for example, Part 1, p. 23). As with Part 1, the emphasis of this paper is on description of the prediction models. You are responsible for supplying valid input and for properly interpreting output.
