Configuration

  • Rate of spread model: Hamada 1 using firebench.ros_models.Hamada_1 implementation.

  • Number of point Sobol: 2^15

  • The spread direction is fixed with (NORMAL_SPREAD_DIR_X, NORMAL_SPREAD_DIR_Y) = (1, 0)

  • The wind speed and wind direction with change in the Sobol sequence and then be projected to get the necessary input for Hamada model WIND_SPEED_U and WIND_SPEED_V.

Specific inputs

  • Number of point Sobol: 32,768 = 2^15

  • The environmental variables chosen for this test are:

    • WIND_SPEED from 0 to 15 m s-1,

    • DIRECTION from 0 to 360 deg,

    • BUILDING_RATIO_FIRE_RESISTANT from 0 to 1.

Results

Fig.1 shows Sobol indices for Hamada 1 model for each fuel class of WUDAPT urban fuel model. The wind direction is the most important parameter with around 65% of the variance explained. Then wind speed is representing less then 20% of the variance. And finally the ratio of fire resistant building is marginal for most fuel class. The small increase in total order shows a existing interaction between parameters (mostly wind direction and speed).
