Description

The Canadian Forest Fire Danger Rating System (CFFDRS) consists of two major sub-systems. The Canadian Forest Fire Weather Index (FWI) System provides numerical ratings of relative fire potential in a standard fuel type, based solely on weather observations. The other major sub-system of the CFFDRS, the Canadian Forest Fire Behavior Prediction (FBP) System, consists of three components as primary outputs: rate of spread. fuel consumption. and line- or frontal fire intensity. An interim version of the rate of spread (ROS) component was produced in 1984 and is described here. The principal input variable is the Initial Spread Index (ISI), a component of the FWI System. Head fire ROS/ISI equations were developed for 14 major Canadian fuel types from a data base consisting of 245 experimental/operational prescribed fire and 45 wildfire observations. Procedures for projecting fire growth are illustrated using a documented wildfire example.
