Fuelbed depth

n. Bulk depth of a fuel layer.

 

  • Discussion

 

Fuelbed depth usually refers to the depth of the surface fuel layer. Albini (1976) suggests fuelbed depth be measured perpendicular to the slope. Such a measurement is valid if the corresponding fuel load is measured along the slope (as assumed for the Rothermelís [1972] surface fire spread model). For fuel loads corrected to a horizontal plane, fuelbed depth should be measured as a vertical distance so that bulk density remains constant.

 

  • Units

     

    Preferred units for fuelbed depth are cm in technical reports and papers. Fire Management in the United States still uses the English units ft or in. See the following fuelbed depth  units conversion table for conversion factors.
