Comparing the Fire Danger Rating Systems of Canada and the US: FWI versus NFDRS
Author: Benjamin SchwarzPublisher: GRIN Verlag
ISBN: 3656732442
Category : Technology & Engineering
Languages : en
Pages : 23
Book Description
Seminar paper from the year 2014 in the subject Forestry / Forestry Economics, grade: 1,3, University of Toronto, language: English, abstract: This paper describes and compares conceptually the Fire Weather Index (FWI) system of Canada and the National Fire Danger Rating System (NFDRS) of the USA. The relatively simple FWI system rates fire danger for all Canada and is based on empirical field-data derived from a single fuel type. The laboratory-based NFDRS, in contrast, allows more specification for distinct fire danger areas and models fuel moisture more abstract and in different classifications. Relative strengths and weaknesses with regard to the vegetative conditions in the particular country are discussed. The use of empirical data and the good and simple representation of soil moisture are the major strengths of the FWI system. The NFDRS wins through its possibility to model specifically a distinct fire danger area and through the consideration of live fuel moisture content. The conclusion of this paper is that both systems can benefit from each other. A combination of the simplicity of the FWI and specialization on a distinct area through the site descriptors similar to the ones of the NFDRS is proposed.
Weather Guide for the Canadian Forest Fire Danger Rating System
Author: B. D. LawsonPublisher:
ISBN:
Category : Fire risk assessment
Languages : en
Pages : 90
Book Description
This weather guide includes detailed specifications for locating and instrumenting fire weather stations, taking weather observations, and overwintering the Drought Code component of the FWI System. The sensitivity of the FWI System components to weather elements is represented quantitatively. The importance of weather that is not directly observable is discussed in the context of fuel moisture and fire behavior. Current developments in the observation and measurement of fire weather and the forecasting of fire danger are discussed, along with the implications for the reporting of fire weather of increasingly automated fire management information systems.

FIRES
Author: Patricia L. AndrewsPublisher:
ISBN:
Category : FIRES (Information retrieval system)
Languages : en
Pages : 68
Book Description
A computer program, FIRES: Fire Information Retrieval and Evaluation System, provides methods for evaluating the performance of fire danger rating indexes. The relationship between fire danger indexes and historical fire occurrence and size is examined through logistic regression and percentiles. Historical seasonal trends of fire danger and fire occurrence can be plotted and compared. Methods for defining critical levels of fire danger are provided. The paper includes a review of NFDRS philosophy and application, a description of input and output, and a summary of fire danger rating programs and data bases and their relationship to FIRES.
