The cost of wildfire suppression in the United States has risen dramatically over the last 20 years. As the interface between wildland and urban areas expands, increased emphasis is being placed on rapid, efficient deployment of firefighting resources. Various numerical models of wildfire spread have been developed to assist wildfire management efforts over the last several decades; however, the use of coupled fire-weather models to capture important feedbacks between the wildfire and the atmosphere is a relatively new development. This seminar will describe a coupled system consisting of the Advanced Regional Prediction System atmospheric model and the raster-based Discrete Event Specification Fire Spread model. After the theoretical basis is outlined, the results of idealized tests and case studies of the September 2000 Moore Branch Fire and the April 2011 Rock House Fire will be presented. The results will demonstrate the importance of coupled fire-atmosphere modeling while highlighting the difficulty of obtaining reliable results at present, motivating plans for future study.
For accommodations based on disability, or more details, please call 325-6561. All visitors without NOAA or University of Oklahoma identification must register at the registration desk on arrival. Visitor parking is available for all University visitors. However, faculty/staff/students must have a current multi-purpose parking permit. Additional parking is available at the Lloyd Noble Center (LNC) for those individuals who do not have a parking permit. You do not need a permit to park in one of 1,200 spaces reserved for CART bus riders, although you must ride the CART shuttle to park in the reserved area. This area is on the north central side of the Lloyd Noble Center. Elsewhere at the LNC, permits are required.
The University of Oklahoma is a smoke-free / tobacco-free campus.
