Wildfires have a significant impact on the properties of the soil. The heat of the fire burns away all of the vegetation and organic matter on the surface of the soil, which makes some nutrients more readily available to the soil while turning others into gases that are lost (chiefly nitrogen).
The points in focus (2) project points onto the image plane (5), but points at different distances (1 and 3) project blurred images.
Fire dynamics is the study of how chemistry, fire science, material science and the mechanical engineering disciplines of fluid mechanics and heat transfer interact to influence fire behavior. In other words, fire dynamics is the study of how fires start, spread and develop.
Just like there is a fire triangle, made up of heat, oxygen, and fuel, there is another triangle called the fire behavior triangle. The three legs of this triangle are fuels, weather, and topography. The sections below go more in depth into each of thise and their influence on fire.
2 aug 2018 with increasing fire frequency under a warming climate, this study the observed effects of wildfire on active layer depth and rate of thaw.
Human impact and fire on the holocene population expansion of fagus. Compute the least-squares line for predicting age from depth.
After large fires and intensive studies of fire history that describe fire patterns over centuries also show that topography plays a major role in determining the patterns of fire. The influence of topography on fire behavior escalates as the slope steepens and increases in complexity.
Natural disturbances such as fire, insects, disease, and erosion alter intrinsic factors, influencing soil forming processes, vegetation development, and site productivity. Potentially, vegetation development and site productivity can be influenced by the use of fire, timber harvesting, and chemical application.
Flame depth is important because the duration of flame exposure and heat burning across a given area can impact the response of the vegetation. Scorch height is the height at which leaves on trees are browned by the heat of the fire.
Analysis of the influence of the heating process on the charring depth of wooden elements.
That decline in current density is known as the skin effect and the skin depth is a measure of the depth at which the current density falls to 1/e of its value near the surface. Over 98% of the current will flow within a layer 4 times the skin depth from the surface.
Topography's effect on fire behavior the term “topography” refers to the earth’s surface, in particular to the character or physical features of a place or region. It is the third of the “big three” influences of fire behavior.

Although other characteristics of a forest will influence the impact of fire upon it, factors such as climate and topography play an important role in determining fire severity and fire extent. Fires spread most widely during drought years, are most severe on upper slopes and are influenced by the type of vegetation that is growing.
Lethal soil the effects of mulch depth and soil moisture on lethal heat duration and degree hours.
