Hamada 1 model validation using WUDAPT urban fuel model
Workflow information
- Documentation page:
- Version: 1.0
- Date of record creation: 2024-12-05
- Date of upload to firebench: 2024-12-05
- Version/tag/commit firebench: 0.3.1
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
andWIND_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).
