The Camp Fire started in the early morning of November 8, 2018 in vegetative fuels to the northeast of Concow, California. Concow is an unincorporated community and census-designated place of primarily residential with a population of 762 in the Sierra

Numerical Modeling of Fire Spread Through Individual Trees and Shrubs

February 19, 2017
Author(s)
William E. Mell, Samuel Manzello, Alexander Maranghides
Fire spread through suspended vegetation, such as tree crowns, is a basic component of wildland fires. Most models of fire spread do not resolve the burning of individual trees. Instead, fire spread through a forest canopy, representing a collection tree

Wildland-Urban Interface Fires: Overview and Research Needs

February 19, 2017
Author(s)
William E. Mell, Samuel Manzello, Alexander Maranghides, Ronald G. Rehm
Wildfires that spread into wildland-urban interface (WUI) communities present a significant challenge on a number of fronts. In the United States the WUI accounts for a significant portion of wildfire suppression and risk mitigation costs. Research on fire

Effects of Wind Speed and Angle on Fire Spread along Privacy Fences

July 25, 2016
Author(s)
Erik L. Johnsson, Alexander Maranghides
A series of experiments was conducted to examine fire spread along fences subjected to wind at various speeds and angles. Specifically, sections of western redcedar, California redwood, or vinyl privacy fences were ignited with a burner. Wind fields of 9 m
