Vinoflot Rs Unification Of Unmanned Aerial Systems And Remote Sensing Practices To Better Analyze Grapevine Health, James M. White

Geography and the Environment: Graduate Student Capstones

Success in agriculture is derived from nutrient-rich soil, well-tilled earth and hands-on attention. In order to meet the needs of increasing food demand, agricultural practices have endured a growing use of chemical and fertilization methods in order to produce higher yields. While the transition to an entirely chemical-free agricultural model is not achievable with regard to the quantity of crop yield, the integration of new technology and updated practices can lessen the amount of chemical and fertilizer adjuncts needed. The purpose of this plan is to offer a lightweight, customizable GIS solution to better understand crop health, in particular grapevines …

The Impact Of Internet Gis On Access To Water Quality Information, Joseph H. Hoover

Electronic Theses and Dissertations

Empowering citizens to comprehend complex environmental issues affecting their daily lives is essential to sustaining a healthy and informed public. The work of many environmental nongovernmental organizations (ENGOs) and institutions of higher education (IHEs) center around helping their stakeholders become informed of, and in turn, better understand complex environmental problems. However, providing individual stakeholders with knowledge about environmental issues that is easily accessible and understandable represents a recurring challenge in today's society. As a result, a gap continues to exist between that which is known about environmental problems and the public's awareness and understanding of those issues. Arsenic contamination of …

Changing Geographic Patterns Of High- And Low-Income Groups In Eight United States Metropolitan Areas, Taylor J. Hafley

Electronic Theses and Dissertations

Income segregation produces unequal social outcomes and has steadily increased since the 1970s. High-poverty neighborhoods suffer from low performing schools, fewer jobs, an evaporation of local role models (Wilson 1987; Reardon and Bischoff 2011a). Recent evidence suggests growing income inequality influences the segregation of affluence more than the segregation of poverty (Reardon and Bischoff 2011b). Metropolitan areas that display strong population and economic growth are susceptible to higher levels of income inequality. I use three unique quantitative approaches to measure the segregation of affluence and poverty in a comparison of four metropolitan areas exhibiting strong growth to four metros with …

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 …

Geography and the Environment: Graduate Student Capstones

Predicting locations of cultural resource in the Walnut Canyon Study Area near Flagstaff, Arizona was accomplished by using geostatistical and spatial analysis techniques of Directional Distribution, Kernel Density, and Average Nearest Neighbor. Known cultural resource sites within Walnut Canyon National Monument were analyzed to identify spatial patterns and densities to apply the results to the study area. Cultural resource sites are predicted to be highly clustered within 200 feet of fresh water sources as well as in woodland and shrub land vegetation types. Results can be used for land-use managers to identify areas to survey with high potential of containing …

Potential Impacts To Resident Populations, Susitna-Watana Hydroelectric Project, Megan Ross

Geography and the Environment: Graduate Student Capstones

In 2014, the Alaska Energy Authority is preparing to construct a hydropower dam on Alaska's Susitna River, known as the Susitna-Watana Hydroelectric Project. Changes to water levels, sediment content, and flow rates are likely to affect the river itself and the salmon that are sustained by the Susitna ecosystem. The potential geomorphological and biological impacts of the dam as they could affect activity in the local communities are studied using currently available data. GIS tools are applied to identify areas of reservoir fill, risk of erosion, and endangerment of salmon habitat; then compare these impact areas to areas used by …

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 …

Determining Home Range And Preferred Habitat Of Feral Horses On The Nevada National Security Site Using Geographic Information Systems, Ashley V. Burns

Geography and the Environment: Graduate Student Capstones

Feral horses (Equus caballus) are free-roaming descendants of domesticated horses and legally protected by the Wild and Free-Roaming Horses and Burros Act of 1971, which mandates how feral horses and burros should be managed and protected on federal lands. Using a geographic information system to determine the home range and preferred habitat of feral horses on the federally managed Nevada National Security Site can enable wildlife biologists in making best management practice recommendations. Site suitability was calculated for elevation, forage, slope, water presence and horse observations and were combined in successive iterations into one polygon. Suitability rankings established …

Montgomery County, Md Public Schools: Student Performance And Achievement Of Low-Income And Minority Students, Richard Joseph

Geography and the Environment: Graduate Student Capstones

The student demographics of Montgomery County Public Schools (MCPS) in Maryland have changed dramatically since 1970 resulting in a majority-minority de facto segregated school system. A major concern of MCPS is the student performance and achievement gap between students of different racial, ethnic, and economic backgrounds.

Using data available from MCSP the performance and achievement of MCPS high school students will be examined for differences between students attending high, medium or low poverty schools. Six high schools will be selected for examination, two for each of the three poverty categories. Primary focus will be to compare the performance and achievement …

Geography and the Environment: Graduate Student Capstones

Ailanthus altissima (Mill.) Swingle, also known as Tree of Heaven, is a non-native tree found throughout North America. The competitive advantages of Ailanthus make it a formidable invader that reduces biodiversity, especially in urban environments. In these areas, Ailanthus can cause structural damage to buildings, pavement, and other infrastructure such as plumbing. Although Ailanthus can commonly be observed throughout neighborhoods of Denver, Colorado, its prevalence and frequency are not well documented. The purpose of this study was to determine the distribution and abundance of Ailanthus among selected urban, residential areas and parks within the City of Denver. This was accomplished …

Welcome Home Ranch Rockshelter: Examinations Of Prehistoric Cultural Transitions In The Palmer Divide, Colorado, Katherine V. Mayo

Electronic Theses and Dissertations

Welcome Home Ranch rockshelter is located in the Palmer Divide region of Colorado. The archaeological evidence on site suggests that this rockshelter was occupied between the Late Archaic period (c. 1000 BC – AD 150) and Early Ceramic period (c. AD 150- 1150). Excavations at Welcome Home Ranch provided a dataset of lithics, ceramics, and features with which to test ideas about prehistoric life during this transitional time frame between the Archaic stage and the Late Prehistoric stage. It is during this transitional time period, c. AD 150, that the Palmer Divide region and its prehistoric residents experienced a variable …

Quantifying Human Impacts On River Bar Morphology Using Digital Photogrammetry, Aaron Zettler-Mann

Electronic Theses and Dissertations

Historically, the study of fluvial geomorphology has been dominated by the field method of surveying using a level and surveying rod. Beginning in the 1980s, the use of ground based and aerial LiDAR increased in popularity as a surveying method. However, LIDAR is expensive and requires significant training to operate. In recent years there has been an increase in the applicability of digital photogrammetry in the field of fluvial geomorphology. Lower costs, streamlined training and an increased accuracy all make digital photogrammetry a promising tool for the field geomorphologist. A study of the morphologic changes of four river bars on …
