Visitors to National Forests in Colorado, Idaho, and Wyoming were asked how their visitation rates would change with the presence of a high-intensity crown fire, prescribed fire, and a 20-yearold high-intensity fire at the area they were visiting. By using pairwise t-tests, visitors to forests in Colorado showed a statistically significant decrease in recreation trips per year with the presence...

The interpretation and communication of fire danger warning levels based on fire weather index values are critical for fire management activities. A number of different indices have been developed for various environmental conditions, and many of them are currently applied in operational warning systems. To select an appropriate combination of such indices to work in different ecoregions in mou...

In the event of an emergency due to a fire or other crisis, a necessary but time consuming pre-requisite, that could delay the real rescue operation, is to establish whether the ground or area can be entered safely by human emergency workers. The objective of the VIEW-FINDER project is to develop robots which have the primary task of gathering data. The robots are equipped with sensors that det...

INTRODUCTION Underground stations can broadly be divided into two methods of construction: cut and cover (i.e. excavating a trench and recovering) and tunnelling. The station layout is mostly comprised of the areas that are common to all stations and their spatial planning must be set out with a thorough understanding of passenger circulation patterns. The station components, namely the ticket ...

This paper presents the application of the agent-based multimethod simulation approach to the development of the Unmanned Ground Vehicle(UGV) simulation testbed prototype to support both concept exploration and the performance-based requirement analysis of future UGVs. We describe the UGV simulation testbed prototype (UGVSimp) incorporating 1) UGV mission scenario, 2) the operational concepts o...

This study examines the nature of water-soluble organic aerosol measured in Pasadena, CA, under typical conditions and under the influence of a large wildfire (the 2009 Station Fire). During non-fire periods, water-soluble organic carbon (WSOC) variability was driven by photochemical production processes and sea breeze transport, resulting in an average diurnal cycle with a maximum at 15:00 loc...

Much research has been carried out on the potential impacts of climate change on forest fire activity in the boreal forest. Indeed, there is a general consensus that, while change will vary regionally across the vast extent of the boreal, in general the fire environment will become more conducive to fire. Land management agencies must consider ways to adapt to these new conditions. This paper e...

In approaches that were previously used, preparedness planning used tactical modelling of individual fire events and resource deployment. Results from modelling individual fire events were typically gathered to construct a program analysis at the planning unit or at the landscape level. This research deviates from those tactical-based approaches by using strategic modelling to inform planning a...
