We investigated the impact of climate change on the number of wildfires in the Peak District uplands of northern England. Wildfires in peat can result in severe carbon loss and damage to water supplies, and fighting such fires is difficult and costly in such a remote location. The Peak District is expected to experience warmer, wetter winters and hotter, drier summers. Local weather simulations...

We use the simulation model Envision to analyze long-term wildfire dynamics and the effects of different fuel management scenarios in central Oregon, USA. We simulated a 50-year future where fuel management activities were increased by doubling and tripling the current area treated while retaining existing treatment strategies in terms of spatial distribution and treatment type. We modeled fore...

Predicting runoff and erosion from watersheds burned by wildfires requires an understanding of the spatial structure of both hillslope and channel drainage networks. We investigate the small-scale and large-scale structures of drainage networks using field studies and computer analysis of 30-m digital elevation model. Topologic variables were derived from a composite 30-m DEM, which included 14...

This study examines how satellite based time-series vegetation greenness data and phenological measurements can be used to monitor and quantify vegetation recovery after wildfire disturbances and examine how pre-fire fuel reduction restoration treatments impact fire severity and impact vegetation recovery trajectories. Pairs of wildfire affected sites and a nearby unburned reference site were c...

Understanding complex social-ecological systems, and anticipating how they may respond to rapid change, requires an approach that incorporates environmental, social, economic, and policy factors, usually in a context of fragmented data availability. We employed fuzzy cognitive mapping (FCM) to integrate these factors in the assessment of future wildfire risk in the Chiquitania region, Bolivia. ...

Physics-Based Wildfire Model Track: EMS, Fire, Disaster Management Author(s): Charles Hall An advanced, physics-based supercomputer/GIS wildfires modeling system has been developed that incorporates chemistry, radiation physics, the local weather and its decisive two-way interactions with the fire, the effects of complex terrain on weather and fire behavior, and represents fuel in three dimensi...

We pose as a challenge to the verification community the problem of finding errors in the specification of a complicated cache-coherence protocol. It specifies a simplified version of the protocol used in an actual multiprocessor computer, except with one error deliberately introduced and another introduced by accident. The protocol and the memory model it is supposed to implement are described...

Pseudomonas tabaci (Wolf and Foster) Stevens, produces an exotoxin, detectable as a bacteriumfree, chlorotic halo, surrounding the necrotic focus of infection in the leaf of a susceptible host at the site of inoculation (Braun, 1955). Garber and Heggestad (1958) reported that species of Nicotiana and varieties of Nicotiana tabacum differed in their susceptibility, ranging from highly susceptibl...

Abstract The intensity of wildfires and wildfire season length is increasing due to climate change, causing a greater threat the local population. Much this population are increasingly adopting social media, sites like Twitter being used as real-time human-sensor network during natural disasters; detecting, tracking documenting events. concept currently largely omitted by models, representing p...
