Burning Index
http://dbpedia.org/resource/Burning_Index
Burning Index (BI) is a number used by the National Oceanic and Atmospheric Administration (NOAA) to describe the potential amount of effort needed to contain a single fire in a particular fuel type within a rating area. The National Fire Danger Rating System (NFDRS) uses a modified version of Bryam's equation for flame length – based on the Spread Component (SC) and the available energy (ERC) – to calculate flame length from which the Burning Index is computed. The equation for flame length is listed below: where: j is a scaling factor,SC is the ,and ERC is the Energy Release Component.

The equation for flame length is listed below: where: j is a scaling factor,SC is the ,and ERC is the Energy Release Component. Consequently, the equation for the Burning Index is: where is the Burning Index scaling factor of (10/ft). Therefore, dividing the Burning Index by 10 produces a reasonable estimate of the flame length at the head of a fire. A unique Burning Index (BI) table is required for each fuel model.
