School: RIO RANCHO HIGH
Area of Science: Environmental Science
Proposal: Research Plan: Analytical Fire Modeling: Expanding upon the Elliptical Fire Theory Phase III
Can the elliptical fire theory modeling process be
both continued upon and validated?
B.Hypothesis- Empirical Testing
If the program’s fire flow follows the experiment’s
fire flow, then the program is valid.
Last phase, a computer modeling process was written to simulate fire flow across a virtual forest environment. Currently it accounts for
Fire growth across differing terrains

Expanding upon the previous work
1. Validation of the computer modeling process developed
Use of empirical cases for comparison against model
Basic fuel testing in a laboratory setting not
burning a forest
2. Expansion of variable accountancy and accuracy
3. Environmental Modeling
Genuine generation of virtual forest terrain through
scanning satellite photos of forest and elevation maps
4. Development of modeling process in a streamlined
Java programming GUI design encapsulating the
A fire test case simulation will be created using basic elements. The experiment will be burned and recorded using a camcorder to record the spread of the fire. From this data other data can be gathered and placed within the program
A variation of the experiment will be performed and the program, not adjusted, will model the experiment. The results will be compared to assess validity of the modeling process.
For example a basic experiment will be set up that consists of two pieces of paper connected. It is burned and the spread of the fire is recorded through a camcorder. The information gathered regarding the traits of the specific fuels will be placed within the modeling program. Then a differing experiment will be created but one containing the same fuel types. There will also be a simulation of this experiment programmed into the modeling program. The two will then be compared. If the program’s fire flow follows the experiment’s fire flow, then the program is valid.
A java application will be used to implement the modeling process as dictated through the java programming language.
1. Risk Assessment

Small enough size to capture with a camcorder and
Basic fuels such as paper and balsa wood
3. Methods of Disposal
Burn Out: The experiment is set to burn out itself
Fire Extinguishment: In case of emergency and fire

Modeling data will be analyzed through recording of values into computer files. Values of interest include spread of fire, spread rates of individual fuels, and environmental factors. Yet, with a computer modeling program any variable programmed into the modeling process can easily be recorded and analyzed.
Empirical Data will be gathered through a camcorder. This data can be analyzed over a time scale and stop frame and data such as spread rates of fuels can be determined by this analysis.
After modeling data and empirical data has been gathered it can be analyzed against each other using statistical tests such as a t test or any test that will plot the correlation of the modeled fire against the empirical testing to determine margin of error of the modeling program.
