Specific learning outcome:

Fire channelling is a major factor in rugged landscapes.

Topic:

The process of fire channelling, and the setting within which it forms.

General Awareness for All Fireground Personnel


Fire channelling occurs when, during conditions of elevated FDI, fire enters a lee-slope eddy or a valley eddy.
With the severity of the fire weather and the thermal heating within the eddy two things ensue:
  1. embers are shed from the top of the eddy, igniting the landscape for some distance downwind; and
  2. the fire within the eddy expands sideways, expanding the area affected by process 1 as well.
