A field investigation was initiated in the summer 1978 to quantify the influence of meteorological factors, ignition method, and fuel conditions on the behaviour of smoke plumes from open field burning. Measurements of air quality and meteorological conditions were performed…

Emissions from prescribed fire vary geographically. In the Northeast, for example, prescribed fires are rare. In other sections, e.g., the southern Coastal Plain, meteorological conditions, terrain, and light fuel loads minimize atmospheric concentrations of emissions. The…

Man began an intensive program to keep fire out of the woods about 70 years ago. Periodic ground fires once common in western pine forests were reduced, and a stand type that had been open, thrifty, and fairly resistant to wildfires lost those characteristics. The current status…

In Australia the long-term ecolgical consequences of forest practices which lead to nutrient depletion may be very serious. In the absence of fertilization, cumulative nutrient depletion associated with intensive management (involving clear-felling, slash burning, and short…

Generalizations of the 'opacity method' of analyzing visible smoke-plume diffusion are presented. The horizontal dispersion length, sigma-y, is derived from the outline of a plume having an arbitrary vertical concentration distribution. The vertical dispersion length, sigma-z,…

A note on the features and control of the ground (soil fires that occur at intervals of 5-8 yr in the Soviet Far East. The winter ground fires occur when the snow cover is incomplete, after a warm dry autumn and when the water table is low. These fires often do not affect the…

Particulate-matter emission factors and Byram's fire-intensity values were computed for experimental backfires in pine-litter and palmetto-gallberry fuels in the Southeast. The combined data for both fuel types were in reasonable agreement with the theoretical prediction that…

In compartment fires a situation often develops in which a layer of oxygen-depleted gases builds up in the upper part of the enclosure. The downward reach of such a layer can be sufficient to make its lower boundary interact with the fire plume. In that case, while the…
