The Importance Of Community Resilience: Developing The American Red Cross International Services Department In The New Hampshire Region, Sarah Romac

Capstone Collection

Disaster management and humanitarian aid organizations have had to reevaluate how communities and individuals can better adapt and prepare for future disaster events. One concept organizations are incorporating into their overall framework is strengthening community resilience. Increasing a community’s resilience level increases its ability to cope with the changes that affect it. Creating awareness of the vulnerabilities in an area, addressing these vulnerabilities with preparedness training, disaster risk reduction (DRR), and sustainable changes made over the long-term can develop a community’s adaptive capacity to be more resilient.

For my practicum, I was given the opportunity to be the International Services …

Spatial Relationships, Movements, And Habitat Associations Of Introduced “Non-Native” Elk Populations On Etolin And Zarembo Islands, Alaska, Jean S. Davidson

Geography and the Environment: Graduate Student Capstones

Etolin and Roosevelt Elk were introduced to Afognak Island, Alaska in 1929 (State of Alaska, 2013). Due to the success of that introduction, Roosevelt Elk and Rocky Mountain Elk were subsequently introduced to Zarembo and Etolin Islands in Southeast Alaska in 1987. Due to the environment of Southeast Alaska, the ability to determine movements, trends, and habitat preferences are limited. In support of the Alaska Department of Fish and Game (ADF&G), this project analyzes the habitat preferences of the elk based upon data from global positioning systems. Locational data is analyzed for proximity to managed lands and considers proximity to …

Predictive Modeling In The Search For Vertebrate Fossils: Geographic Object Based Image Analysis (Geobia) In The Eocene Of Wyoming, Bryan Bommersbach

Masters Theses

The development and testing of predictive models for identifying productive fossil localities represents a promising interdisciplinary endeavor among geographic information scientists, paleoanthropologists, and vertebrate paleontologists. This thesis analyzed high resolution (2m spatial resolution) commercial satellite imagery from the Worldview-2 satellite of five areas of the Great Divide Basin using a GEographic Object-Based Image Analysis (GEOBIA) technique, which segments the image into spectrally homogeneous, multi-pixel image objects. In addition to allowing statistical analysis of the spectral characteristics of the image objects, GEOBIA techniques also let analysts incorporate expert knowledge and contextual information to improve classification accuracy. The spectral characteristics of the …

Mapping And Analyzing Historical Sanborn Maps Of San Luis Obispo From 1905 And 1950, Troy A. Lawson

Social Sciences

This project was conducted to map, analyze, and determine historical changes in the city of San Luis Obispo, California. Sanborn maps from 1905 and 1950 were drawn showing streets, parcels, creeks, and buildings of the city. These publications had limited use because they were in a physical format without any geographic reference. Here, these maps were digitized into a GIS format to analyze building trends and identify cultural and historical buildings not on the City’s list of Historic and Culturally Contributing Buildings, as well as published online on the City of San Luis Obispo’s website and on ArcGIS Online. Additionally, …

Geography Faculty Publications and Presentations

This report provides an overview of the key patterns that emerged from the spatial analyses of the destination and route data collected during the 2013 Sustainable Roads workshops on the Mount Baker Snoqualmie (MBS) National Forest. We excluded the pilot workshop data from the analyses because a somewhat different process was used to collect the mapped data. The data used in the analysis was collected from 262 participants in eight workshops (Bellingham, Sedro-Woolley, Darrington, Monroe, Everett, Seattle, Issaquah, Enumclaw). During the workshops, participants mapped up to eight destinations of importance to them, and in most cases, also mapped the routes …

Powering The Future: Siting Guidelines For Renewable Wind Energy Development In Eastern Colorado, Zach Ancona

Geography and the Environment: Graduate Student Capstones

Wind energy is one of the fastest growing renewable energies around the world. The United States contains approximately 49,000 active wind turbines and Colorado accounts for less than 3 percent of that number, even though Colorado ranks 11^th in the nation for wind development potential. The siting process for wind development is lengthy, taking from 5 to 10 years, and many facilities that are proposed end up not being built due to complications from inadequate pre-siting techniques. The research in this report aims to identify high priority areas in eastern Colorado through the examination of key variables used in …

Spatial Analysis Of Post-Hurricane Katrina Thermal Pattern And Intensity In Greater New Orleans: Implications For Urban Heat Island Research, Aram P. Lief

LSU New Orleans Theses and Dissertations

In 2005, Hurricane Katrina’s diverse impacts on the Greater New Orleans area included damaged and destroyed trees, and other despoiled vegetation, which also increased the exposure of artificial and bare surfaces, known factors that contribute to the climatic phenomenon known as the urban heat island (UHI). This is an investigation of UHI in the aftermath of Hurricane Katrina, which entails the analysis of pre and post-hurricane Katrina thermal imagery of the study area, including changes to surface heat patterns and vegetative cover. Imagery from Landsat TM was used to show changes to the pattern and intensity of the UHI effect, …

Climate Change Vulnerabilities: Case Studies Of The Maldives And Kenya, Katherine A. Peinhardt

This paper examines the political and social vulnerabilities of climate change, with the use of two salient case studies, the Republic of the Maldives and Kenya as exemplars of effects observed and projected. The susceptibilities for each nation are examined, with unique sensitivities highlighted and common themes synthesized between the two states. Examples of existing conflict, and implications of projected territorial conflict will be discussed. Policy outcomes will also be discussed for the situation of each nation, each with its own set of contextual sensitivities in the face of climatic shifts. Generalized policy options will be proposed for the common …

Interannual Variations And Trends In Global Land Surface Phenology Derived From Enhanced Vegetation Index During 1982–2010, Xiaoyang Zhang, Bin Tan, Yunyue Yu

GSCE Faculty Publications

Land surface phenology is widely retrieved from satellite observations at regional and global scales, and its long-term record has been demonstrated to be a valuable tool for reconstructing past climate variations, monitoring the dynamics of terrestrial ecosystems in response to climate impacts, and predicting biological responses to future climate scenarios. This study detected global land surface phenology from the advanced very high resolution radiometer (AVHRR) and the Moderate Resolution Imaging Spectroradiometer (MODIS) data from 1982 to 2010. Based on daily enhanced vegetation index at a spatial resolution of 0.05 degrees, we simulated the seasonal vegetative trajectory for each individual pixel …

Validation Of Satellite Rainfall Products For Western Uganda., Jeremy E. Diem, Joel N. Hartter, Sadie J. Ryan, Michael W. Palace

Geography

Central equatorial Africa is deficient in long-term, ground-based measurements of rainfall; therefore, the aim of this study is to assess the accuracy of three high-resolution, satellite-based rainfall products in western Uganda for the 2001–10 period. The three products are African Rainfall Climatology, version 2 (ARC2); African Rainfall Estimation Algorithm, version 2 (RFE2); and 3B42 from the Tropical Rainfall Measuring Mission, version 7 (i.e., 3B42v7). Daily rainfall totals from six gauges were used to assess the accuracy of satellite-based rainfall estimates of rainfall days, daily rainfall totals, 10-day rainfall totals, monthly rainfall totals, and seasonal rainfall totals. The northern stations had …

Addressing Water Resource Issues In Barbados Through An Isotopic And Atmospheric Characterization Of Precipitation Variability, Veronica Hall

Masters Theses & Specialist Projects

Numerous studies have analyzed isotopic variation of meteoric and dripwater in karst environments for paleoclimate reconstructions or aquifer recharge capacity. What is poorly understood is how the isotopic signal of δ¹⁸O and δ²H is transferred through the hydrologic cycle based upon storm type, frequency, intensity, and teleconnection activity in the tropical karst areas. At Harrison’s Cave, Barbados, a Hobo Onset event data logger was attached to a tipping bucket rain gauge to count the tips and record the total rainfall every 10 minutes. In the cave a Hobo data logger was used to record relative humidity …

Impacts Of Carbonate Mineral Weathering On Hydrochemistry Of The Upper Green River Basin, Kentucky, Laura Leigh Osterhoudt

Masters Theses & Specialist Projects

Kentucky’s Upper Green River Basin has received significant attention due to the area’s high biodiversity and spectacular karst development. While carbonate bedrock is present throughout the watershed, it is more extensive and homogenous along the river between Greensburg and Munfordville than upstream from Greensburg where the geology is more heterogeneous. This research quantitatively evaluated how lithological differences between the two catchment areas impact hydrochemistry and inorganic carbon cycling. This first required correcting catchment boundaries on previous US Geological Survey Hydrologic Unit Maps to account for areas where the boundaries cross sinkhole plains. Basin boundaries using existing Kentucky Division of Water …

Land Cover Change And Its Impacts On A Flash Flood-Producing Rain Event In Eastern Kentucky, William N. Rodgers

Masters Theses & Specialist Projects

Eastern Kentucky is a 35-county region that is a part of the Cumberland Plateau of the Appalachian Mountains. With mountaintop removal and associated land cover change (LCC) (primarily deforestation), it is hypothesized that there would be changes in various atmospheric boundary layer parameters and precipitation. In this research, we have conducted sensitivity experiments of atmospheric response of a significant flash flood-producing rainfall event by modifying land cover and topography. These reflect recent LCC, including mountaintop removal (MTR). We have used the Weather Research and Forecasting (WRF) model for this purpose. The study found changes in amount, location, and timing of …

Impact Of Soil Moisture–Atmosphere Interactions On Surface Temperature Distribution, Alexis Berg, Benjamin R. Lintner, Kirsten L. Findell, Sergey Malyshev, Paul C. Loikith, Pierre Gentine

Geography Faculty Publications and Presentations

Understanding how different physical processes can shape the probability distribution function (PDF) of surface temperature, in particular the tails of the distribution, is essential for the attribution and projection of future extreme temperature events. In this study, the contribution of soil moisture–atmosphere interactions to surface temperature PDFs is investigated. Soil moisture represents a key variable in the coupling of the land and atmosphere, since it controls the partitioning of available energy between sensible and latent heat flux at the surface. Consequently, soil moisture variability driven by the atmosphere may feed back onto the near-surface climate—in particular, temperature. In this study, …

Integrating Seismic Activity Into Land Use Management: A Case Study From Central Arkansas Using Hazus Software Application, Robert Dean Breashears

Graduate Theses and Dissertations

Almost 20 years after a remarkable swarm of more than 30,000 micro-earthquakes, a new swarm revisited the same region of central Arkansas, less than 30 miles northeast of Conway, Arkansas. A main shock on May 4, 2001 of magnitude MR = 4.4 was followed by a large number of aftershocks in a small crustal volume about 2,500 events for about 2 months. Preliminary locations of aftershocks from the portable network together with the locations based on data from regional networks lead us to conclude that both swarms (2001 and 1982) occupy virtually the same crustal volume. In following years several …

Graduate Theses and Dissertations

The purpose of this study is to determine the relationship between physical distance from the headquarters, number of years working within the Division of Agriculture, and job title compared to mission statement and goal focus. The Division of Agriculture as part of the University of Arkansas System is a unique organization because many of its employees are not physically located at the headquarter locations of Little Rock and Fayetteville. The Cooperative Extension Service, part of the Division of Agriculture, has at least one office in each of Arkansas's 75 counties as well as faculty and staff members located at five …

Local Regulatory Protection For Ecosystem Services: A Case Study From The Karst Region Of Southeast Minnesota, Usa, Mary A. Williams, Susy Ziegler

Journal Articles

Human communities depend upon a myriad of ecosystem goods and services, which are produced by and depend on natural environmental processes occurring at multiple temporal and spatial scales. Land-use policy seldom recognizes the importance of these services or the environmental processes generating these services. This study examined the degree to which ecosystem services and supporting environmental processes are regulated at two United States municipal levels: city and county. Several ecosystem services but few environmental processes are regulated to some extent. We identified policy needs for environmentally sensitive karst features, aquifer recharge, groundwater quality, plant and animal populations, and flood mitigation. …
