Download or read book Field Procedures for Verification and Adjustment of Fire Behavior Predictions written by Richard C. Rothermel and published by . This book was released on 1983 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: The problem of verifying predictions of fire behavior, primarily rate of spread, is discussed in terms of the fire situation for which predictions are made, and the type of fire where data are to be collected. Procedures for collecting data and performing analysis are presented for both readily accessible fires where data should be complete, and for inaccessible fires where data are likely to be incomplete. The material is prepared for use by field units, with no requirements for special equipment or computers. Procedures for selecting the most representative fuel model, for overall evaluation of prediction capability, and for developing calibration coefficients to improve future predictions are presented. Illustrated examples from several fires are included. The material is a companion publication to the fire prediction manual titled, 'INT-GTR-143: How to predict the spread and intensity of forest and range fire' by R. C. Rothermel.

Available in PDF, EPUB and Kindle. Book excerpt: A mathematical fire model for predicting rate of spread and intensity that is applicable to a wide range of wildland fuels and environment is presented. Methods of incorporating mixtures of fuel sizes are introduced by weighting input parameters by surface area. The input parameters do not require a prior knowledge of the burning characteristics of the fuel.

Book excerpt: Data that represent average worst fire weather for a particular area are used to index daily fire danger; however, they do not account for different locations or diurnal weather changes that significantly affect fire behavior potential. To study the effects that selected changes in weather databases have on computed fire behavior parameters, weather data for the northern Rocky Mountains were treated as probability distributions, then used in computer simulation to estimate distributions of rate-of-spread (ROS) and fireline intensity (FLI). Sensitivity of ROS and FLl to weather input changes was analyzed by varying the source and amount of weather data, and diurnally adjusting temperature and relative humidity. In eight representative cases, a minimum amount of data produced the lowest cumulative probabilities of ROS and FLl, and data from a higher elevation produced the highest values. For long-term planning, within the region studied, a small subset of weather data distributions was adequate for estimating probabilistic distributions of ROS and FLI. Joint probabilities of ROS and FLI differed substantially among test cases. Fire behavior values obtained with observed data were higher than those obtained with diurnally adjusted data. The simulation techniques used are appropriate for use in long-term fire management planning models.

This book was released on 2018-10-02 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Drought Estimation in Southern Forest Fire Control During extended droughts, aerial fuels become more flammable, fire lines are hard to build and hard to hold, fires burn with great intensity and high rate of spread, and sometimes high-intensity fires produce convection columns that spew firebrands for long distances. As examples of what can happen during prolonged periods of little rain, in 1955 and 1956 four fires in the South each burned more than acres. Drought conditions coupled with certain atmospheric conditions caused this excessive loss. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

This book was released on 2018-01-09 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Probability of Fire Occurrence Can Be Predicted The percentage relationship between actual and expected fires is independent of year-to-year variations in fire occurrence and so shows how much the factors not included in the meter rating influenced fire occurrence. Since changes in population and area protected have been minor, and activities on the national forest have remained fairly constant, it is reasonable to conclude that the relative decrease in fire occurrence is largely a result of effective fire prevention. The above relationships are based on all causes of fires. Data for a single cause or for a particular prevention program can be analyzed similarly. Weaknesses in the prevention program can be revealed in this way and steps taken to remedy them. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Download or read book Potential Spotting Distance from Wind Driven Surface Fires Classic Reprint written by Frank a Albini and published by Forgotten Books. This book was released on 2017-10-27 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Potential Spotting Distance From Wind-Driven Surface Fires A model is presented here for intermediate-range spotting in which a spreading surface fire, idealized as a straight line perpendicular to the direction of the wind, provides the source of buoyancy that lofts firebrand particles above the ground for transport downwind. Short - range spotting of a few tens of meters from fires of low intensity is not addressed. Also not addressed is the very long-range spotting of tens of kilometers associated with severe fire phenomena such as the establishment of fire whirls or sustained spread of fire through the crowns of timber stands. These unique phenomena require separate treatments. Not considered in this model is the probability that there exists a firebrand particle in the fuel complex that has the particular size that will permit it to be a maximum-distance spot fire source. Particles that are too small can be lofted to a greater height than that of the maximum - distance particle, but they will burn out before returning to the ground. Larger particles cannot be lofted so high, and thus will not travel as far. The probability of ignition by a firebrand particle is also not addressed in this paper. What is predicted is the distance to which a viable firebrand could be carried. If it fails to land upon a suitable fuel to ignite, or if the fire ignited fails to spread, no spot fire will occur.

Download or read book Field Guide to the Canadian Forest Fire Behaviour Prediction FBP System written by Stephen William Taylor and published by University of Washington Press. This book was released on 1997 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Canadian Forest Fire Behaviour System is a systematic methodfor assessing wildland fore behaviour potential. The guide provides a simplified version of the system, presented in tabular format. It was prepared to assist staff in making first approximations of FBP system outputs when computer-based applications arenot available. Quantitative estimates of head fire spread rate, fire intensity, type of fire, and elliptical fire area, perimeter, and perimeter growth rate are provided for sixteen discrete fuel types within five broad groupings (coniferous, deciduous, and mixedwood forests, logging slash, and hrass), covering mostof the major forest fuel types found in Canada. The FBP system is intended to supplement the experience and judgment of fire managers.
