This book was released on 2002 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 2000-01, aspen decline was observed over large areas of north-east Ontario. This study analyzes the bioclimatic characteristics of the areas affected and suggests potential causes of the decline. The bioclimatic characteristics analyzed include forest tent caterpillar defoliation; drought history; forest composition, age, & structure; and soil quality.

Download or read book Diurnal Variation in the Fine Fuel Moisture Code written by B. D. Lawson and published by Canadian Forest Service. This book was released on 1996 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forest fire managers must be able to predict the normal variation in fine fuel moisture around the clock, since it is a critical factor that affects the behaviour and control of wildfires and prescribed burns. The Canadian Forest Fire Weather Index System contains a Fine Fuel Moisture Code (FFMC) that produces a standard daily index of expected fine fuel moisture at the mid-afternoon peak of fire danger, but does not output normal diurnal variation in FFMC. This paper documents the development and updating of an earlier model of diurnal variation in FFMC, presents the underlying equations and a lookup table, and announces the availability of a computer program version of the model for various user applications.

Available in PDF, EPUB and Kindle. Book excerpt: Describes a model for predicting moisture content of fine fuels for use with the BEHAVE fire behavior and fuel modeling system. The model is intended to meet the need for more accurate predictions of fine fuel moisture, particularly in northern conifer stands and on days following rain. The model is based on the Canadian Fine Fuel Moisture Code (FFMC), modified to account for solar heating of fuels and to predict diurnal trends in fine fuel moisture. The model may be initiated without extensive data on prior weather. When compared to the FFMC and the fire behavior officers' procedures, the new model gave consistently better predictions over the complete range of fuel conditions.

This book was released on 1984 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fourth edition of tables for calculating the six standardcomponents of the Canadian Forest Fire Weather Index System. Thefirst three components are fuel moisture codes that follow dailychanges in the moisture contents of three classes of forestsfuel; the final three are fire behaviour indexes that representrate of spread, amount of available fuel, and fire intensity. The system provides a uniform method of rating fire danger acrossCanada.

This book was released on 1992 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Canadian Forest Fire Behavior Prediction (FBP) System is a subsystem of the larger Canadian Forest Fire Danger Rating System, which also includes the Canadian Forest Fire Weather Index (FWI) System. The FBP system provides quantitative estimates of head fire spread rate, fuel consumption, fire intensity and fire description and gives estimates of fire area, perimeter, perimeter growth rate and flank and back fire behaviour. This report describes the structure and content of the system and its use with forest fire characteristics.

Download or read book Ground truthing the Drought Code written by Bruce D. Lawson and published by . This book was released on 1996 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Users of the Canadian Forest Fire Weather Index System are required to precede computation of the drought code component each spring by first calculating a mathematical model of overwinter recharge of moisture in the forest floor. Limitations of the model, required for operational simplicity, have led to requests for a field sampling procedure that can be used to verify the model when and where desired. This report describes a standard procedure for destructively sampling the forest floor by depth class, oven-drying the material, and comparing the actual moisture contents against empirically derived regression equations of forest floor moisture versus drought code for representative mature coastal and interior British Columbia forests, and for white spruce forests in southern Yukon. The field verification procedures and calibration equations presented will be applicable to drought code start-up at any time during the fire season.

Download or read book Canadian Forest Fire Behavior Prediction FBP System written by Kelvin G. Hirsch and published by UBC Press. This book was released on 1996 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Canadian Forest Fire Behaviour Prediction (FBP) System provides a systematic method of assessing fire behaviour. The FBP System has 14 primary inputs that can be divided into 5 general categories: fuels, weather, topography, foliar moisture content, and type and duration of prediction. In the FBP System these inputs are used to mathematically develop 4 primary and 11 secondary outputs. Primary outputs are generally based on a fire intensity equation, and secondary outputs are calculated using a simple elliptical fire growth model. This publication provides diagrams, examples, and exercises that explain the FBP System in a user-oriented manner. This guideline delineates the interpretation of the FBP System's inputs and outputs and details how the predictions are derived.
