Research scientists and forest resource managers have been trying to develop models for wildfire behavior for a long time. The present work gives an overview about the first steps in fire simulation and risk monitoring in the Black Forest National Park. The over-all aim is to use a fire growth simulation modeling system called FARSITE for the first time in the Black Forest. The program requires spatial data themes such as elevation, slope, aspect, fuel model, and canopy cover along with separate weather and wind data. The first step therefore was to create or obtain all the necessary data. The second goal was to investigate differences in modeling outputs using the two different implemented standard fuel model sets, developed by Anderson (1982) and Scott and Burgan (2005).
The output parameters were rate of spread, fire line intensity and time of arrival. The results for the two sets of fuel models show that there is a clear difference in the size of the burned area, as well as in the intensity and propagation speed of the fire. But they also show, that the fire behavior is strongly dependent on the selected fuel classes. The fuel model map is the key input for the simulation model.
This work represents a first step in the application of fire spread modeling in the Black Forest National Park for wildfire risk monitoring and management. The work provides first insights into the application and accuracy of FARSITE in the National Park. In addition, initial recommendations for the improvement and adaptation of FARSITE to the investigation area are formulated.
