الملخص	The Rothermel fire spread model, developed by Richard Rothermel in 1972, is a mechanistic mathematical model that predicts the rate of fire spread through surface fuels using fuel characteristics, weather, and topography. It forms the theoretical foundation of the BEHAVE fire modeling system used operationally by fire agencies worldwide. The model integrates principles from combustion physics, heat transfer, and fuel science to quantify how fire intensity, fuel moisture, wind, and slope interact to drive wildfire propagation.	The Van Wagner crown fire model predicts the conditions under which surface fires will transition to active crown fires and the rate of crown fire spread. Developed by Cornelius Van Wagner in the 1970s–1990s, the model is grounded in the physics of heat transfer from the surface flame to the canopy and the rate of vertical flame propagation. The model is used to assess crown fire danger and to guide fuel management decisions in forests with high canopy flammability.
