ABSTRACT

The objective of this study is to find out what effects the changes in slope and wind velocity has on characteristic changes in fire behavior through a simple burning experiment. Both upslope and downslope were considered for slope factor and the conditions of 0m/s, 2m/s, 4m/s and 6m/s were applied for wind velocity factor. The result of this study shows that, with the higher upslope and wind velocity, the flame temperature continues to increase up to 1,353.3°C. The rate of spread was also found to be as fast as 15m/min in the condition of 30° slope and 6m/s wind velocity. The conditional fire intensity was estimated to range from 78.11 kW/m to 5,982.23 kW/m and also increased with the higher slope and wind velocity, which was similar to findings in the literature for other countries. The result of this study will help to predict accurately the spread and intensity of forest fire.
