BehavePlus fire modeling system, version 5.0: Variables

Abstract

This publication has been revised to reflect updates to version 4.0 of the BehavePlus software. It was originally published as the BehavePlus fire modeling system, version 4.0: Variables in July, 2008.The BehavePlus fire modeling system is a computer program based on mathematical models that describe wildland fire behavior and effects and the fire environment. It is a flexible system that produces tables, graphs, and simple diagrams. It can be used for a host of fire management applications including projecting the behavior of an ongoing fire, planning prescribed fire, fuel hazard assessment, and training. The BehavePlus program automatically creates a worksheet that requests the required input variables based on the modules, output variables, and options selected by the user. This is a reference paper that describes the 189 variables in BehavePlus, with information on input and output relationships. A User's Guide describes operation of the program and can be accessed at http://www.fs.fed.us/rm/pubs/rmrs_gtr106.html.

The pyrogeography of eastern boreal Canada from 1901 to 2012 simulated with the LPJ-LMfire model

“…Annual processes are defined in terms of several sources of mortality, seedling establishment, reproduction, allocation, and tissue turnover (Smith et al, 2001;Sitch et al, 2003). The computational core of SPITFIRE is based upon Rothermel-type surface fire behaviour models (Rothermel, 1972;Andrews et al, 2008) and is designed to simulate processes of natural fires and their impacts on vegetation mortality and fire emissions (Thonicke et al, 2010). The LMfire module simulates lightning ignitions based upon a daily time step and uses fuel bulk density and fuel moisture to calculate the fire's rate of spread, intensity, and fire-related mortality.…”

Building Fuel Models and Simulating Their Surface Fire Behavior in the “Serra De Itabaiana” National Park, Sergipe, Brazil

“…The 6 m open terrain wind speed was adjusted to midflame height using wind adjustment factors of 0.5 for the grass fields, 0.3 for the shrublands, and 0.15 for the tropical forests (Table 4). The exposition factors were based on Andrews (2008). Slope steepness "SRTM" maps on the Global Mapper 10.0 defined that the terrain slope steepness varies between 0 and 50 degrees in Serra de Itabaiana National Park.…”

“…The BehavePlus fire modeling system is a computer program for personal computers. It is based on mathematical models that predict fire behavior (such as flame length and transition to crown fire), fire effects (such as scorch height and tree mortality), and the fire environment (such as fuel moisture and wind adjustment factor) (ANDREWS, 2008).…”

A new wildland fire danger index for a Mediterranean region and some validation aspects

“…32 Between 1998 and2009, in the Community of Valencia (CV) (Fig. 1), the Mediterranean Spanish autonomous region 33 where this study was carried out, each year an average of 500 fires affected 14,000 ha, 50% of which was woodland 34 (DGMNPF 2006(DGMNPF , 2010.…”

“…Therefore, we have obtained the probability of ignition using the methodology of BEHAVE which 136 takes into account fuel shading, FDFMC and air temperature (Andrews 2009 …”
