Surface Modeling Topsoil Distribution On A Reclaimed Coal-Mine Site At Blackmesa Mine Complex, Kayenta, Arizona, Janine Ferarese

Geography and the Environment: Graduate Student Capstones

A necessary precursor to ensure proper vegetation growth on reclaimed coal-mine areas is even distribution of topsoil. This capstone discusses development of surface models to describe the accurate determination and visualization of the distribution of topsoil. Prediction surfaces from topsoil-depth point samples were created using the surface interpolation methods, Inverse Distance Weighted and Kriging. The validity and accuracy of each method was assessed to determine the best method to evaluate actual topsoil distribution at a coal mining site. The model can be utilized by non- spatially trained personnel working in the mining arena as an aid in assessing how appropriately …

Meanwhile, UR also proposes to rehabilitate the corridor in their new Master Plan. Nevertheless, until now, no substantive studies exist on the trail or the corridor linking the trail to the south side of the James River through the …

Beyond The Epsilon Band: Polygonal Modeling Of Gradation/Uncertainty In Area-Class Maps, Barry Kronenfeld

Faculty Research and Creative Activity

A spatial modeling technique is proposed to represent boundary uncertainty or gradation on area-class maps using a simple polygon tessellation with designated zones of indeterminacy or transition zones. The transition zone can be conceptualized as a dual of the epsilon band, but is more flexible and allows for a wide range of polygonal configurations, including polygons with sinuous boundaries, spurs, three-way transition zones, and null polygons. The model is specified using the medial axis to capture the general shape characteristics of a transition zone. Graph theoretic representation of an extended version of the medial axis captures key junctions in both …

Geography Faculty Publications and Presentations

This study investigated potential impacts of climate change on travel disruption resulting from road closures in two urban watersheds in the Portland metropolitan area. We used ensemble climate change scenarios, a hydrologic model, stream channel survey, a hydraulic model, and a travel forecast model to develop an integrated impact assessment method. High-resolution climate change scenarios are based on the combinations of two emission scenarios and eight general circulation models. The Precipitation-Runoff Modeling System was calibrated and validated for the period 1988-2006, and simulated for determining the probability of floods from 2020-2049. We surveyed stream cross sections at five road crossings …

Exploiting The Power Law Distribution Properties Of Satellite Fire Redaiative Power Retrials: A Method To Estimate Fire Radiative Energy And Biomass Burned From Sparse Satellite Observations, S. S. Kumar, David P. Roy, L. Boschetti, R. Kremens

GSCE Faculty Publications

Instantaneous estimates of the power released by fire (fire radiative power, FRP) are available with satellite active fire detection products. The temporal integral of FRP provides an estimate of the fire radiative energy (FRE) that is related linearly to the amount of biomass burned needed by the atmospheric emissions modeling community. The FRE, however, is sensitive to satellite temporal and spatial FRP undersampling due to infrequent satellite overpasses, cloud and smoke obscuration, and failure to detect cool and/or small fires. Satellite FRPs derived over individual burned areas and fires have been observed to exhibit power law distributions. This property is …

Review Of Hard Grass: Life On The Crazy Woman Bison Ranch. By Mary Zeiss Stange, Linda M. Hasselstrom

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

Twenty years ago, Stange and her husband traded a modest New Jersey house for seven square miles of overgrazed prairie and set out to right the wrongs done to a place that had been mismanaged ecologically as well as environmentally. The restoration begins disastrously with llamas before it proceeds to success with bison. Her narration includes her own experiences, but most of her essays are serious, in-depth studies of the broader topics that constitute life in the great grasslands spreading across the interior of the country. She begins with prehistory, analyzing the evolution of both plants and animals in the …

From Lakes To Plants: Spatial Assessment Of Vegetation Dynamics Along 52 Disappearing Lakes In The Boreal Forests Of Alaska From 1984-2009 In The Yukon Flats Wildlife Refuge, Steve Ewest

Geography and the Environment: Graduate Student Capstones

A spatial assessment of vegetation change along the areas of shrinking lakes was conducted in 2011. The analysis utilized Landsat TM/ETM imagery bands 3 and 4 to calculate NDVI (normalized difference vegetation index) from 1984 to 2009 and applied cell and zonal statistics to measure the change as well as create an animation of the change. Also, three 30 meter bands and the zonal averages for the maximum values were assessed. The band in the 60-90 buffer bands has the greatest ratio amount of the maximum vegetation values when compared to the 0-30 meter and the 30-60 meter buffered bands. …

Coca And Conservation: Cultivation, Eradication, And Trafficking In The Amazon Borderlands, David S. Salisbury, C. Fagan

Geography and the Environment Faculty Publications

The cultivation and traffic of coca, Erythrolxylum coca, and coca derivatives remain understudied threats to the conservation of the Amazon rainforest. Currently the crop is transforming land use and livelihoods in the ecologically and culturally rich borderlands of Amazonian Peru. The isolated nature of this region characterized by indigenous populations (both settled and uncontacted), conservation units, resource concessions, and a lack of state presence provides fertile ground for the boom and bust cycle of coca production and facilitates the international transport of the product to neighboring Brazil. This paper explores the social and environmental impacts of coca production, eradication, and …

Geopolitics Of The Kaliningrad Exclave And Enclave: Russian And Eu Perspectives, Alexander Diener, Joshua Hagen

Geography Faculty Research

Two U.S. political geographers examine a range of geopolitical issues associated with the shifting sovereignty of Russia's Kaliningrad Oblast (a part of the former German province of East Prussia) during the 20th century, as well as the region's evolving geopolitical status as a consequence of the European Union's enlargement to embrace Poland and Lithuania. They argue that Kaliningrad today can be considered a "double" borderland, situated simultaneously on the European Union's border with Russia as well as physically separated from Russia, its home country, by the surrounding land boundaries of EU states. Although technically neither an exclave nor an enclave, …

The Ecology Of San Luis Obispo: A Children's Book, Heidi Van Campen

Social Sciences

San Luis Obispo is one of the most loved places in the world by its residents and visitors. Located halfway between San Francisco and Los Angeles, San Luis Obispo is the heart of California's Central Coast. However, this paper is not about the present-day cities or residents. It is an ecological history; the story of life and land over time.

Historians tend to treat nature as the setting for history, rather than a participant. Ecology is a history written knowing that we shape our environment and it shapes us.

This is a story of the ecology of San Luis Obispo.

Assessing Seasonal Features Of Tropical Forests Using Remote Sensing, Roberto Bonifaz-Alfonzo

Department of Geography: Dissertations, Theses, and Student Research

Tropical forests are key components of the biogeochemical cycles, complex in structure, diversity and dynamics, also, tropical regions have been deforested and modified by human activities particularly for agriculture. Understanding the inter-annual and intra-annual variation dynamics of tropical regions could give valuable information on temporal characteristics of ecosystems behavior which is important for mapping and monitoring. This dissertation assesses seasonal and inter-annual changes in the tropical land cover that may be related to changes in the natural environment and/or human activities. Research was focused on the Mayan forest located in southern Mexico and Northwest Guatemala, one of the northern-most important …

Defining The Regional And Seasonal Climatic Response Of Long Douglas-Fir Tree-Ring Chronologies In Central Mexico, Grant Howard West

Graduate Theses and Dissertations

Problems with instrumental climate data and difficulties arising from the distribution of sensitive, long-term tree-ring chronologies across Mexico's complex terrain have made it difficult to model the climate signal of tree-rings in Mexico. The objective of this research is to utilize the improved long-term, high-resolution, gridded instrumental climate dataset for Mexico recently developed by Zhu and Lettenmaier (2007) to document the climate signal of Douglas-fir in central Mexico. Through correlation analysis between five Douglas-fir tree-ring chronologies created by the University of Arkansas-Fayetteville Tree-Ring Laboratory and Zhu and Lettenmaier's (2007) gridded historical climate dataset, this research aims to define the regional …

On June 5th 2009, an estimated thirty people died in a clash between governmental authorities and indigenous people near Bagua, Peru. Termed the "Bagua Massacre," this event underscores the marginalized role of Indigenous Amazonians when confronting multinational commercial interests supported by the state (Shepard, 2009). The indigenous people were protesting the “Law of the Jungle,” Decree 1090, a 2009 decree assuming heavily-forested indigenous lands idle and unproductive, and providing the legal basis to privatize comunally-held forests to facilitate petroleum, biofuel, hydroelectric and logging projects. Since contact, the assumption of indigenous people unproductively managing their forested homelands has fueled colonization, deforestation, …
