The Keetch–Byram drought index (known as KBDI), created by John Keetch and George Byram in 1968 for the United States Department of Agriculture's Forest Service, is a measure of drought conditions. It is commonly used for the purpose of predicting the likelihood and severity of wildfire .
Since 1995, the US Forest Service has slowly incorporated burning practices into its forest management policies. [ 10 ] Fire suppression has changed the composition and ecology of North American habitats, including highly fire-dependent ecosystems such as oak savannas [ 54 ] [ 55 ] and canebrakes, [ 56 ] [ 57 ] which are now critically ...
Forest-fire models have been developed since 1940 to the present, but a lot of chemical and thermodynamic questions related to fire behaviour are still to be resolved. Scientists and their forest fire models from 1940 till 2003 are listed in article. [6] Models can be divided into three groups: Empirical, Semi-empirical, and Physically based.
The fire was one of several that burned throughout the weekend in New Jersey, New York, Massachusetts, Pennsylvania and Connecticut – the result of historically dry conditions across the region ...
Note, however, that according to Pruessner et al. (2002, 2004) the forest-fire model does not behave critically on very large, i.e. physically relevant scales. Early versions go back to Henley (1989) and Drossel and Schwabl (1992). The model is defined as a cellular automaton on a grid with L d cells. L is the sidelength of the grid and d is ...
A wildfire, forest fire, or a bushfire is an unplanned, uncontrolled and unpredictable fire in an area of combustible vegetation. [ 1 ] [ 2 ] Depending on the type of vegetation present, a wildfire may be more specifically identified as a bushfire ( in Australia ), desert fire, grass fire, hill fire, peat fire, prairie fire, vegetation fire, or ...
Also referred to as air attack. The use of aircraft in support of ground resources to combat wildfires, often most effective in initial attack in light fuels. air drop The delivery of supplies or fire retardant from the air. Supplies can be dropped by parachute, while retardant is generally released in a single drop of one or more trails, the size of which is determined by the wind and the ...
More research followed and in 1965 a research project headquartered in Seattle was established to provide a fresh look at the needs and requirements for a national, fire danger, rating system. After canvassing many fire control agencies across the country, the Seattle research group recommended new directions for research that would lead to the ...
