Rothermel surface fire spread model and associated developments: A comprehensive explanation

View report

This report is an outstanding complete description of not only the Rothermel model, but also the modifications and addendums that have evolved for supporting the many systems that use the model. This work shows all the equations, discusses their relevance, and illustrates graphically their response to changes in their inherent variables. The variables required for driving the models referred to as inputs, which must be obtained to describe the environment in which the fire is burning, are often misunderstood.
