Forest fire spread and intensity were modeled as a function of wind and fuel. Spread rate and intensity of forest fire were related to weight and thickness of forest fuel beds and to wind speed. Forest fire spread rate and fire intensity were differentiated according to wind speed. Rapid wind speed causes a faster forest fire spread rate and greater fire intensity than does slow wind speed. Relative burning time of the fire from beginning to end in the model was 161 sec at a wind speed of 0.5 m/sec and 146 sec at 1 m/sec on the model. Average forest fire spread rate was 0.014 m/sec at a wind speed of 0.5 m/sec and 0.020 m/ sec at 1 m/sec. Average fire intensity was 0.183 kW/m at a wind speed of 0.5 m/sec, 0.259 kW/m at 1 m/ sec. Fire intensity was greater when forest fire spread rate was rapid.
