S-390 - Introduction to Wildland Fire Behavior Calculations


This course is designed to introduce fire behavior calculations by manual methods, using nomograms and the Fireline Handbook Appendix B: Fire Behavior, PMS 410-2. Students gain an understanding of the determinants of fire behavior though studying inputs (weather, slope, fuels, and fuel moisture). Students also learn how to interpret fire behavior outputs, documentation processes, and fire behavior briefing components.
