Abstract: |
Fire spread is the outcome of complex interactions between fire, fuels, terrain, and weather. Most models created to predict fire spread fall into one of two classes, empirical models and physical models. For empirical models (Finney, 1998), fire spread is measured under controlled conditions and a statistical relationship found between fire spread and each variable tested (Rothermal, 1972). The model typically is represented in two dimensions through predetermined geometry, for example, overlapping ellipses (Alexander, 1985). Empirical models have skill at low to moderate winds. However, at higher wind speeds and under conditions that produce erratic fire behavior, statistical/empirical methods are less skillful because the equations were not derived for such conditions. |
