Modeling a Historic Forest Fire Using Gis and Farsite

Recent major wildfires may result from a combination of climate change and fuel buildup due to fire exclusion policies of the last century. Are such fires unique to the forests and climate of the 21st century or are they similar to historic fires? Historic fires are recorded primarily by eye witness accounts which seldom contain information needed to examine them with modern fire management too...

A convection model for fire spread simulation

We present a convection model which can be coupled with fire propagation models in order to take into account the wind and the slope which are two of the most relevant factors affecting surface fire spread. An asymptotic analysis gives a three dimensional convective model governed by a two–dimensional equation.

Relating surface fire spread to landscape structure: An application of FARSITE in a managed forest landscape

Recent studies suggest that manipulation of landscape patterns is the most preferred method to reduce susceptibility of landscape to fire spread. e evaluated the effects of landscape spatial pattern and spatial heterogeneity of fuel loading on surface fire spread using the FARSITE model n Chequamegon National Forest landscape, Wisconsin. Five forest management scenarios were developed to genera...

Mathematical Model Of Forest Fire Initiation And Spread

One of the objectives of these studies is the improvement of knowledge on the fundamental physical mechanisms that control the crown forest fire initiation and spread. Under specific conditions, a surface forest fire spreading through the ground cover is converted into a crown fire that moves through crown at a significantly greater rate than the surface fire, and hence is more dangerous ecolog...

Verification & validation of an agent-based forest fire simulation model

In this paper, we present the verification and validation of an agent-based model of forest fires. We use a combination of a Virtual Overlay Multi-Agent System (VOMAS) validation scheme with Fire Weather Index (FWI) to validate the forest fire Simulation. FWI is based on decades of real forest fire data and is now regarded as a standard index for fire probability with wide usage across Canada, ...
