Author: Richard C. Rothermel
Publisher:
ISBN:
Category : Flame spread
Languages : en
Pages : 168
Book Description
This manual documents procedures for estimating the rate of forward spread, intensity, flame length, and size of fires burning in forests and rangelands. Contains instructions for obtaining fuel and weather data, calculating fire behavior, and interpreting the results for application to actual fire problems.

The Photoload Sampling Technique
Author: Robert E. Keane
Publisher:
ISBN:
Category : Coarse woody debris
Languages : en
Pages : 50
Book Description
Fire managers need better estimates of fuel loading so they can more accurately predict the potential fire behavior and effects of alternative fuel and ecosystem restoration treatments. This report presents a new fuel sampling method, called the photoload sampling technique, to quickly and accurately estimate loadings for six common surface fuel components (1 hr, 10 hr, 100 hr, and 1000 hr downed dead woody, shrub, and herbaceous fuels). This technique involves visually comparing fuel conditions in the field with photoload sequences to estimate fuel loadings. Photoload sequences are a series of downward-looking and close-up oblique photographs depicting a sequence of graduated fuel loadings of synthetic fuelbeds for each of the six fuel components. This report contains a set of photoload sequences that describe the range of fuel component loadings for common forest conditions in the northern Rocky Mountains of Montana, USA to estimate fuel loading in the field. A companion publication (RMRS-RP-61CD) details the methods used to create the photoload sequences and presents a comprehensive evaluation of the technique.

Forest Fires
Author: Edward A. Johnson
Publisher: Elsevier
ISBN: 0080506747
Category : Technology & Engineering
Languages : en
Pages : 617
Book Description
Even before the myth of Prometheus, fire played a crucial ecological role around the world. Numerous plant communities depend on fire to generate species diversity in both time and space. Without fire such ecosystems would become sterile monocultures. Recent efforts to prohibit fire in fire dependent communities have contributed to more intense and more damaging fires. For these reasons, foresters, ecologists, land managers, geographers, and environmental scientists are interested in the behavior and ecological effects of fires. This book will be the first to focus on the chemistry and physics of fire as it relates to the ways in which fire behaves and the impacts it has on ecosystem function. Leading international contributors have been recruited by the editors to prepare a didactic text/reference that will appeal to both advanced students and practicing professionals.

The Effects of Thinning and Similar Stand Treatments on Fire Behavior in Western Forests
Wildland Fire Danger Estimation and Mapping
Author: Emilio Chuvieco
Publisher: World Scientific
ISBN: 9789812791177
Category : Nature
Languages : en
Pages : 284
Book Description
The book presents a wide range of techniques for extracting information from satellite remote sensing images in forest fire danger assessment. It covers the main concepts involved in fire danger rating, and analyses the inputs derived from remotely sensed data for mapping fire danger at both the local and global scale. The questions addressed concern the estimation of fuel moisture content, the description of fuel structural properties, the estimation of meteorological danger indices, the analysis of human factors associated with fire ignition, and the integration of different risk factors in a geographic information system for fire danger management.

Fire Behavior in Black Spruce-lichen Woodland
Author: Martin E. Alexander
Publisher:
ISBN:
Category : Forest fires
Languages : en
Pages : 66
Book Description
The behaviour of single point-ignition and line-ignition experimental fires was studied in upland black spruce-lichen woodland stands at Porter Lake in the Caribou Range of the Northwest Territories from June 26-July 8, 1982. The experimental burning project objective was to relate the head fire rate of spread (ROS) in this fuel type to the initial spread index (ISI) component of the Canadian Forest Fire Weather Index System. The experimental fire plots varied in size from 0.02 ha-0.65 ha. and the live tree overstory averaged about 1200 stems/ha and 5.0 m in height. The lichen layer averaged about 3.5 cm in depth. Three point-ignition fires, seven line-ignition fires, and one wildfire were documented over a wide range of burning conditions. A relationship for equilibrium fire spread in black spruce-lichen woodland stands was established.
