Rothermel's model states that extreme fire behavior is not predicted.

Rothermel's model states that extreme fire behavior is not predicted.

• A. True
• B. False
• C. Indeterminable
• D. Irrelevant

Answer: (A)

Rothermel’s model is a steady-state, semi-empirical approach for predicting surface-fire spread in uniform fuels. It calculates the rate of spread and related fire characteristics based on fuel properties, wind, slope, and moisture under constant conditions. Because it’s built to describe typical surface-fire behavior and does not incorporate dynamic feedbacks or processes that cause extreme events (such as rapid accelerations, crown-fire transitions, spotting, or wind-driven blowups), it does not predict those extreme behaviors. So the statement is true: extreme fire behavior is not predicted by Rothermel’s model.
