Notes: |
||
Fuel Moisture content values are given on a dry weight basis. |
||
Wind magnitude (speed) was varied from 0 m/s to 10 m/s. Magnitudes in the upper range are meant to mimic Santa Ana conditions. |
||
Slope was varied from 0% to 100%. At 100% slope there is a 1 meter change in vertical elevation for every 1 meter of horizontal distance. |
||
Wind magnitude (speed) in slope trials was set to 0 m/s. |
