1. introduction extensive fires in the forests are examples of natural crises (hosseinali, 2005) and forest fire events are increasing in the conditions of changing climate and global warming; (azizi and yousefi, 2005). this phenomenon is considered one of the most destructive factors for forest ecosystems, causing irreparable damages (marozas et al, 2007). some of these damages include land us...

Forest fires are a critical natural disturbance in most of the forested ecosystems around the globe, including the Canadian boreal forest where fires are recurrent. Here, our goal was to develop a new daily-scale forest fire danger forecasting system (FFDFS) using remote sensing data and implement it over the northern part of Canadian province of Alberta during 2009–2011 fire seasons. The daily...

Forest fires are considered natural phenomena but the magnitude of the problem can be attributed to poor forest management and to the extreme weather conditions. Furthermore, the abolishment of traditional activities related to forests has sent away people from the forests that they used to protect them. The aforementioned reasons result in the annual destruction of large forest areas, agricult...

this study was conducted to investigate the effects of applying methods andamount of ammonium polyphosphate (0, 2 and 4 wt%) on fire retardancy andmechanical properties of wood flour/polypropylene composites. the resultsshowed that addition of fire retardant improved the mechanical properties such astensile and flexural strengths and fire retardancy of composites. but by increasingof fire retar...

As climate warms, snow-water storage is decreasing while forest fires are increasing in extent, frequency, and duration. The majority of occur the seasonal snow zone across western US. Yet, we do not understand broad-scale variability fire effects on water resource availability. Using pre- post-fire data from 78 burned SNOTEL stations, evaluated shifts accumulation (snow-water storage) snowmelt...

Effects of fire suppression policies on semi-arid yellow pine and mixed conifer (YPMC) forests in the western US have been well documented, and restoration of forest structure and natural fire regimes are high management priorities to ensure the health and resilience of such forests. However, determining reference conditions for ecological restoration is difficult due to the near absence of und...

This paper is a progress report of a MCEER research project on the development of multihazard protection technologies for critical facilities. One important component is to consider earthquake and earthquake induced hazards (e.g. fire, haz-mat leakage, power outrage, etc). This paper is concerned with earthquake and subsequent fire hazards. Records from historical earthquakes show that sometime...

Fire emissions, smoke dispersion, and air quality are very important for fire fighting and planing of prescribed burning. BlueskyRAINS (BSR) is a comprehensive and state-of-the-art Decision Support System (DSS) for fire managers and air quality managers to plan fuels treatments and support state air quality smoke regulatory actions, especially related to prescribed fires. BSR has been created b...

This study aims to classify the Drought Code in North Sumatra. is part of Fire Danger Rating System (FDRS) developed Canada. One sub-systems FDRS Weather Index (FWI) that evaluate fire hazards from current and past weather conditions. classified by using Support Vector Machine. Machine widely used data classification process. advantages methods it has ability classifying large amount more than ...
