S-490, Advanced Fire Behavior Calculations

Course Overview Page ButtonAdministration Button

Course Description

This is the fourth course in a series designed to develop fire behavior and prediction knowledge and skills. This course prepares students for Advanced Fire Behavior Interpretation, S-590, which addresses the skills for Fire Behavior Analyst and Long Term Fire Analyst positions. It also prepares students desiring to become qualified as a Prescribed Fire Burn Boss Type 1 (RXB1). The course material is presented in an instructor-led approach to learning. Examples and exercises are divided between wildfire and prescribed fire applications. Students learn to project fire perimeter growth based on weather predictions, and knowledge of fuels and topography, using a variety of scenarios. A course update is available at https://www.nwcg.gov/course-updates-page and additional instructor developed course materials are available by contacting the Fire Environment Curriculum Subcommittee: https://www.nwcg.gov/committees/fire-environment-curriculum-subcommittee.

Course Objective:

  • Collect and evaluate fire behavior prediction model inputs and compute wildland fire behavior using advanced techniques.
  • Use fire behavior models to predict fire growth in varied terrain.
  • Define likely conditions for extreme fire behavior and potential impacts on safety.
  • Interpret, communicate, apply, and document wildland fire behavior and weather information.
