76 Li, DapengModeling wildfire evacuation as a coupled human-environmental system using triggersWildfire is a common hazard in the western U.S. that can cause significant loss of life and property. When a fire approaches a community and becomes a threat to the residents, emergency managers need to take into account both fire behavior and the expected response of the threatened population to spread modeling; GIS; reverse geocoding; traffic simulation; triggers; wildfire evacuation2016
77 Bishop, Seth ArthurSpatial access and local demand for emergency medical services in utahEmergency Medical Services form the backbone of the prehospital emergency medical care system in the United States.

80 Matheson, Daniel ScottEvaluating the effects of spatial resolution on hyperspectral fire detection and temperature retrievalHyperspectral remote sensing of wildfires combines principles of emitted radiation with advanced spectrometry to model wildfire area and temperature, as well as background land cover classification, at the subpixel level. Yet airborne hyperspectral sensors face problems of inconsistent spatial resol...AVIRIS; Hyperspectral; Remote sensing; Spatial scaling; Spectral mixture analysis; Wildfires2011-08
81 Jin, ZhenyuMapping and spatial-temporal modeling of Bromus tectorum invasion in Central UtahCheatgrass, or Downy Brome, is an exotic winter annual weed native to the Mediterranean region. Since its introduction to the U.S., it has become a significant weed and aggressive invader of sagebrush, pinion-juniper, and other shrub communities, where it can completely out-compete native grasses a...Cheatgrass; NDVI time-series; Remote sensing; Spatial-temporal modeling; Utah; Bromus tectorum2011-11
82 Schaaf, Abigail NUsing hyperspectral data to classify vegetation at the plant functional type-level in mountain terrain at three spatial resolutionsHyperspectral data covering the visible, near infrared, and shortwave infrared portions of the electromagnetic spectrum have been used to map vegetation at the plant functional type and species levels in a variety of ecosystems. Vegetation maps are basic to the study and analysis of natural resourc...Hyperspectral; Mountain terrain; Plant functional type; Spatial resolution; Spectral mixture analysis; Vegetation classification2010
83 Salter, Richard GeneTooele Valley, Utah: A regional interpretation of the changing economiesThis is a study of the physical and cultural geography of a small, well defined area - Tooele Valley, Utah. This is a regional study, attempting to show how a group of people have adapted to the limitations imposed upon their particular culture and to indicate the workable relationships they have e...Tooele Valley, Utah1953-08
84 Meng, RanStudy of two vegetation-related disturbances (beetle herbivory and wildfire) in the western united states using optical remote sensingVegetation disturbances, such as insect outbreaks and wildfires, exist in various terrestrial ecosystems across the entire world. In this dissertation, I implemented two vegetation-related disturbances studies in the western United States: (1) Mapping and spectroscopic analysis of tamarisk defoliati...Change detection; Disturbance ecology; Remote sensing classification; Spaital analysis; Statistical modeling; Vegetation recovery2015
85 Nicolosi, Emily AnnGeographies of climate change mitigation: an exploration of the climate change movementThe climate change movement shares a single grievance that it seeks to address, climate change, but within this movement there are different perspectives on, first, what solutions are most appropriate and, second, what the fundamental problem is to be addressed. Looking at these two factors through ...carbon footprint; climate change; climate change mitigation; geography; social movements; Transition Towns2015
86 Ward, Danielle MarieHolocene chemostratigraphy of spring sediments in range creek canyon, utahRange Creek Canyon in southeastern Utah is the location of hundreds of well-preserved Fremont archeological sites. To determine what living conditions for the Fremont were like during their occupation of Range Creek from 200 AD and 1350 AD, elemental ratios and grain size data were used as proxies f...2016
87 Wellard, Blake H.A new ancestral diploid species of echinocereus endemic to southwestern utah and northern arizonaEchinocereus relictus B. Wellard is a newly described diploid (2n=22) species that is the presumed ancestor of the tetraploid (2n=44) E. engelmaniii. Echinocereus engelmannii subsp. engelmannii represents both diploid and tetraploid cytotypes.

88 Reynolds, Joshua DeshawnComparing urban vegetation cover with summer land surface temperature in the salt lake valleyThe climate of urban areas is influenced by the composition and configuration of different land cover types. Urban forests increase human comfort in urban areas by cooling the environment through evapotranspiration and shade. A tradeoff of urban forests in semiarid and arid climates is that they req...Land Surface Temperature; Lidar; Orthoimagery; Random Forest; Salt Lake; Urban Forest2017

Retail transnational corporations have expanded rapidly in this emerging market. Yet relatively little is known about how they have embedded in the Chinese market and expanded spati...China; hypermarket; land use; retail internationalization; Suzhou; urban growth2016
90 Meadows, Michelle KristineHigh frequency variability in glacier meltwater patterns in the rhone watershed, switzerlandGlaciers contribute to the hydrology of many mountainous watersheds worldwide. Significant attention has been given to seasonal discharge measurements and modeling and relatively little to shorter timescale glacier discharge; thus, our understanding of high frequency variability is more limited.

93 Powell, AshleyUnderstanding the relationship between fire, climate, and population in Central Uganda from 1990-2010Fire is a form of natural disturbance that can keep ecosystems in balance, but fire in Africa is neither entirely natural nor anthropogenic due to the hundreds of thousands of years of coexistence between fire and humans. In central Uganda fires can easily reach the size of 200 km and fire is an eff...Climate; Fire; Population; Remote Sensing; Uganda2012-12
