Fire behavior fuel model
n. The set of fuelbed inputs needed by the Rothermel (1972) surface fire spread model.
The set of fuelbed inputs specified in a fire behavior fuel model include: fuel load by size class and category (live or dead), surface-area-to-volume ratio by size class and component, heat content by fuel category, fuelbed depth, and dead fuel moisture of extinction. Other fuelbed inputs needed by the Rothermel (1972) surface fire spread model but held constant for all fire behavior fuel models include: fuel particle mineral content and fuel particle density. Standard fire behavior fuel models for broad application are available; users may define a custom fire behavior fuel model for situations not well represented by a standard fire behavior fuel model.
