Model reveals the complete flow regime around the fire establishing:
  1. Presence or lack of in-draft
  2. In-draft velocity
  3. Transition distance between the Immediate (1) and Far Field (2) zones at which flow changes direction
  4. Appropriate distance for placing counter-fires

(1) Immediate Zone - place close to fire where flow is in the opposite direction to in-draft
(2) Far Field Zone - begins where Immediate Zone ends and stretches downstream. In-draft is observed there.
These houses could potentially be saved using counter-fires
