Effects Of Stormwater Green Infrastructure On Watershed Outflow: Does Spatial Distribution Matter?, Benjamin Fahy, Heejun Chang

International Journal of Geospatial and Environmental Research

Green Stormwater Infrastructure (GSI) has become a popular method in urban stormwater management. We examined how spatial distribution of GSI affected rainfall-runoff relationships in a recently developed neighborhood in Gresham, Oregon, USA for the 2017-2018 water year. Runoff ratio, peak discharge, and flashiness were compared under four precipitation scenarios (of differing intensity and duration) and different spatial arrangements of GSI. Distributed GSI reduced runoff ratio (10 - 20%), peak discharge (26 - 68%), and flashiness index (56 - 70%). Distributed GSI outperformed centralized structures for all metrics, reducing runoff ratio (22 - 32%), peak discharge 67 to 69%, and flashiness …

Everyday Perseverance & Meaningful Toil: Mapping The (In)Distinguishable Process Of Recovery Post-Hurricane Katrina, New Orleans, Louisiana, Monique Hassman

Theses and Dissertations

For nearly a century, anthropological scholarship on disaster has contributed to advancing emergency preparation and management, however examination focusing on survivors’ return and responses in the aftermath of catastrophe, specifically the ways in which residents work to recover—if at all—remains far from comprehensive, especially in urban, post-industrial settings.

Following calamity, what remains? What is disturbed? What becomes reconstructed? Who repairs the tattered social fabric or restores the built environment? And how do these processes transpire? These questions summarize the research interests of this dissertation, which examines the place-making practices not of experts or administrators, but, rather, those enacted by (extra) …

A Player’S Sense Of Place: Computer Games As Anatopistic Medium, Kristopher John Purzycki

Theses and Dissertations

This project works to understand how open-world computer games help generate a sense of place from the player. Since their development over a half century ago, computer games have primarily been discussed in terms of space. Yet the way we think about space today is much different than how those scientists calculated space as a construction of time, mass, and location. But as computer games have evolved, the language has failed to accommodate the more nuanced qualities of game spaces. This project aims at articulating the nuances of place through phenomenological methods to objectively analyze the player experience as performed …

Spatial Dimensions Of Drilling Technologies: Controversies Over Unconventional Oil And Gas Development In Northern Colorado, Nicholas J. Schuelke

Theses and Dissertations

This dissertation investigates three controversies surrounding oil and gas development in populated areas of the Front Range region of northern Colorado that have emerged as a result of renewed interest in developing unconventional hydrocarbon resources using horizontal drilling and hydraulic fracturing techniques. These controversies surround disputes between competing capital interests over rights of access to subsurface hydrocarbon resources, municipal challenges in accommodating oil and gas development in residential areas, and perceptions among more ‘moderate’ residents regarding activism resisting oil and gas development in Colorado and alternative strategies adopted by these residents to oppose hydrocarbon extractive activities in their neighborhoods. Through …

Visualization Of Uncertain Boundaries Of Undersea Features, Hyowon Ban, Hyo Hyun Sung

International Journal of Geospatial and Environmental Research

There have been several studies that detect, measure, analyze, and visualize the undersea features by using technologies in multiple disciplines including geography and oceanography. However, definitions of the undersea features often vary among the existing leading literature. Due to this reason the geographical boundary for a certain undersea feature is sometimes not identical among the definitions. In this study, we explore semantic uncertainty in the definitions of some undersea features and apply approaches from fuzzy-set theory and geographic information science on empirical bathymetric data to visualize the uncertain boundaries of the undersea features. Results from this study demonstrate that the …

Using Historic Glo Data And Gis To Assess The Potential For Local Bison Bison Near Two Wisconsin Late Prehistoric Oneota Localities, Andrew Michael Saleh

Theses and Dissertations

Bison (Bison bison) remains are rare in the archaeological record of Wisconsin. This thesis uses a Geographic Information System (GIS) to better understand native vegetation near sites with reported bison bone to assess their ecological viability to support local bison herds. The distribution of bison bone recovered in archaeological contexts in Wisconsin can be summarized as follows: few sites report bison remains, the archaeological contexts that do report bison are clustered in a few Late Prehistoric period locations (approximately A.D. 1300-1650), and bison remains are rare in comparison to other fauna at those sites (Arzigian et al. 1989; Boszhardt 1989, …

Socio-Spatial Disparities In Dementia Mortality In The United States, Wei Xu

Theses and Dissertations

Mainly due to the expansion of the geriatric population, the number of deaths attributable to dementia in the United States is likely to increase rapidly in the coming decades. In the hope of offering some valuable insights into discovering disease risk factors linked to geography, advocating place-based prevention and intervention strategies and supporting equitable access to end-of-life care, this study examines three aspects of socio-spatial disparities in dementia mortality in the U.S.: (i) small area spatial and temporal variations in dementia mortality risk; (ii) “place effects” on the differentials in individual dementia mortality risk; and (iii) disparities in place of …

A Conceptual Modeling Framework For Hydrological Ecosystem Services And Its Application To The Impacts Of Climate Change And Urban Expansion, Feng Pan

Theses and Dissertations

Ecosystem services (ESs) are used as intermediates for researchers, stakeholders, and the public to understand and deal with the current environmental situation and problems, and ESs-related studies have drawn increasing attention. The quantitative assessments of ESs to calculate how much the ecosystem can benefit human beings and society, are still under development. Hydrological ESs, a subset of ESs that is related to water bodies and the surrounding environment, carry several challenges and opportunities for both hydrological and ESs modeling. Specifically, new quantitative tools with the capability to simulate explicit spatial and temporal scales are desired, and such tools should be …

Temporal Trends And Origins Of Lake Erie Cadmium Contamination In Relation To Sediment Substrate Type Using Multivariate Kriging Analyses, Danielle E. Mitchell, K. Wayne Forsythe, Chris H. Marvin, Debbie A. Burniston

International Journal of Geospatial and Environmental Research

Using the kriging spatial interpolation method, Cd sediment contamination in Lake Erie from 1971 (263 samples) and 1997/1998 (55 samples) were mapped as continuous data surfaces. Although the most recent data set is two decades old, the roughly 25 year period between the two comprehensive lake-wide surveys represents a period of intense binational management action to reduce sources of contamination. To improve interpolation accuracy between two different sampling densities, auxiliary variables including lake-wide sediment substrate types were integrated into spatial analysis of Cd contamination patterns. The potential for adverse biological impacts posed by Cd sediment contamination to humans and aquatic …

Using Gis And Remote Sensing To Map Grassroots Sustainable Development For A Small Ngo In Nepal, Suzanne C. Walther, Elizabeth M. Dengenis, Krishna Gurung

International Journal of Geospatial and Environmental Research

Geographic information systems, through analysis and visualizations, can aid in pursuing and improving sustainable development. Thousands of Non-Governmental Organizations (NGOs) in developing countries provide a wide range of services and local organizations with fewer resources must often be more efficient to offer their services effectively. The accessibility of spatial data for assessment and, in turn, improved planning could enable these organizations to increase efficiency, thereby maximizing aid and sustainable development, as well as the number of people helped in a variety of ways. Focusing on mapping outreach and quantifying land use for a locally run NGO in Nepal, this study …

Implications Of Dam Removal: Modeling Streamflow In Lansing, Michigan Using The Soil And Water Assessment Tool, Ryan J. Filbin, Laiyin Zhu, Lisa Dechano-Cook, Lei Meng

International Journal of Geospatial and Environmental Research

This paper uses hydrologic modeling methods to determine the effects of dam removal in Lansing, Michigan, on the streamflow of the Grand River, flooding risks, and flood mitigation strategies. In Michigan, more than one-half of the state’s dam infrastructure is more than 50 years old, and more than one-third are classified as having a moderate-to high-risk potential. Lansing, Michigan, contains two moderate-to high-risk dams along the Grand River that are a significant hazard to the surrounding community in the event of structural failure. This research utilizes the Soil and Water Assessment Tool (SWAT) to model the impacts of the Moores …

Impacts Of Climate Change And Urban Expansion On Hydrologic Ecosystem Services In The Milwaukee River Basin, Feng Pen, Woonsup Choi

Geography Faculty Articles

Land use/land cover (LULC) and climate changes could affect water quantity and quality and thus hydrologic ecosystem services (ES). However, studies of these impacts on hydrologic ES are limited by the current methods and techniques. We attempted to find out how the LULC and climate changes impact hydrologic ES at different temporal scales so that decision-makers can easily understand hydrologic ES variations for guiding management plans. In this study, we analyzed the impacts of LULC and climate changes on hydrologic ES in the Milwaukee River basin, USA with a conceptual modeling framework for hydrologic ES. The model framework was applied …

Changes In The Extent And Distribution Of Urban Land Cover In The Democratic People's Republic Of Korea (North Korea) Between 1987 And 2010, Sangjun Kang, Jinmu Choi, Hyejin Yoon, Woonsup Choi

Geography Faculty Articles

Largely due to data unavailability, the spatial pattern of urban growth in North Korea has been rarely studied. This study explored urban changes in North Korea and provided their plausible causes. The present study used satellite-based land cover datasets produced by the government of South Korea to examine the extent and distribution of urban land cover in North Korea between the late 1980s (1987-1989) and late 2000s (2008-2010) at the municipal level. Urban Expansion Intensity Index (UEII) was calculated for two ten-year intervals and the spatial autocorrelation of UEII values was examined. Major findings from the study are summarized as …
