DOWNLOAD EBOOK →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 EBOOK →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.

DOWNLOAD EBOOK →Accurate, high-resolution fire behavior prediction is a critical component of fire management decision-making before and during fires. Prometheus is a deterministic fire growth simulation model that was developed to help fire managers to understand the probable consequences of their decisions. It uses spatial input data on topography (slope, aspect, and elevation), fuel types, and weather to simulate fire growth by applying Huygens principle of wave propagation to the rate-of-spread predictions from the Canadian Forest Fire Behavior Prediction System of the Canadian Forest Fire Danger Rating System. This approach produces detailed fire perimeters at user-specified display time step intervals. Each active vertex along the perimeter has corresponding fire behavior output. Exported fire perimeters are compatible with geographic information systems. Additionally, three interpolation techniques are available to produce optional raster fire behavior outputs. This report documents the structure of the Prometheus model and an assessment of its performance. The report includes a general discussion of approaches to the modeling of fire growth simulation and explains the vector propagation technique used in Prometheus. The limitations and assumptions of applying the model, as well as the most appropriate directions for future research, are also discussed.

DOWNLOAD EBOOK →Fire is a defining element in Canadian land and life. With few exceptions, Canada's forests and prairies have evolved with fire. Its peoples have exploited fire and sought to protect themselves from its excesses, and since Confederation, the country has devised various institutions to connect fire and society. The choices Canadians have made says a great deal about their national character. Awful Splendour narrates the history of this grand saga. It will interest geographers, historians, and members of the fire community.
Diurnal Variation in the Fine Fuel Moisture Code

DOWNLOAD EBOOK →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.

DOWNLOAD EBOOK →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.

DOWNLOAD EBOOK →"In September 2004, the Canadian Council of Forest Ministers established a federal, provincial, and territorial task group of assistant deputy ministers (ADMs) and commissioned the development of the Canadian Wildland Fire Strategy (CWFS). The ADMs created an intergovernmental team of analysts, experienced fire managers, and researchers, known as the CWFS Core Team, to consult with Canadian and international experts, collate information, conduct analyses, and present the findings. This team was directed to assess the current state of wildland fire management in Canada, examine the key influences and trends, and identify possible desired future states and how they could be achieved. This publication comprises a collection of nine reports written by the CWFS Core Team members and their associates. Collectively these papers include syntheses, analyses, and perspective articles that address a variety of the social, economic, and biophysical aspects of wildland fire and its management as well as policy, science, and operational issues in Canada."--Pub. desc.
