Title: The Next Generation Soil Heating Model

Project Proposal Abstract: Accurately modeling the duration and extent of soil heating from prescribed fires and wildfires is vital to predicting many second-order fire effects, including development of soil hydrophobicity and other biological, chemical, and physical effects. Advancements have been made in the process-based soil heating models that consider soil heating a function of soil characteristics, fuel consumption, and moisture content. Nevertheless, current models of soil heating during fires have not been sufficiently evaluated under a variety of actual burning, soil, or fuel conditions. We propose to assess a new soil heating model which models soil temperature, soil water potential and soil water vapor under a variety of soil, fuel, and burning conditions with existing field-collected datasets. This complex model better incorporates the physio-chemical processes that describe evaporation of soil moisture and the transport of soil water vapor and liquid water that occur during fires. In addition, we propose to develop a simplified version of this new model by solving the changes in soil moisture and vapor algebraically rather than dynamically changing partial differential equations. We will test the simplified soil heating model using the same statistical techniques and soil heating data sets, and incorporate the model into the Interagency Fuels Treatment Decision Support System (IFTDSS) framework. The deliverables of the proposed work are: 1) a publication on evaluating the existing model; 2) a publication on the simplified soil heating model; 3) a documented soil heating model (computer code) incorporated into the IFTDSS framework; and 4) archiving the existing soil heating datasets.
