Current fire danger and fire behavior prediction focuses on the flaming stage of combustion, while fire effects and resistance to control are governed by smoldering and residual combustion in heavy fuels and organic soil layers. Fuel combustion algorithms in current use are based on exchange of moisture between sound, cylindrical woody fuels and the atmosphere, and are inadequate to predict moisture transport in porous fuels such as duff and moss layers. Flaming combustion in shrub types, and smoldering propagation in large rotten logs, older stumps, and deep organic layers, are poorly understood and not modeled. This National Fire Plan research project was funded to: (1) provide a national fuel moisture and danger rating system that includes modeling of duff and moss moisture dynamics; (2) provide a simulation model of smoldering propagation in rotten and ground fuels; (3) assess the limits of flaming, smoldering, and residual combustion of shrub biomass, rotten woody logs, stumps, and ground fuels (moss, duff); (4) model heat and moisture transport within porous fuels and between fuels and the atmosphere; and (5) design and develop the next version of Consume software (version 4) for managers and scientists containing the new theoretical and empirical fuel consumption models formulated from this project.
