A Gis-Based Model To Assess On-Site Sewage Facility (Ossf) Contamination Risk To Local Water Resources, Alvaro Garcia

Theses and Dissertations

In a collaborative effort between Texas Water Resources Institute (TWRI), Cameron County Public Health (CCPH), Texas A&M AgriLife Extension (TAMAE), and the University of Texas Rio Grande Valley (UTRGV), a GIS database that includes relevant OSSF information, such as location, system age, lot size, and other important parameters was created.

This OSSF database, along with publicly available GIS data, was used to create an integrative GIS-based risk assessment model where OSSF risk parameters were assigned a risk factor and combined into a spatial contamination risk for surrounding areas and their receiving waterbodies. Parameters were broken down into two categories: environmental …

Modeling The Spatial Distribution Of The Current And Future Ecosystem Services Of Urban Tree Planting In Chicopee And Fall River, Massachusetts, R. Moody, N. Geron, M. Healy, J. Rogan, Deborah Martin

Geography

Mature urban tree canopy cover disrupts the local effects of urban heat islands and provides important ecosystem services such as energy savings through evaporation and shading, pollution removal, storm runoff control, and carbon sequestration. Sustainable urban tree canopy relies on the planting of juvenile trees. Typically, tree planting programs are only evaluated by the number of trees planted and there is a lack of analysis of juvenile trees post-planting. This study examines the value and distribution of energy savings provided by juvenile trees and how that value changes considering predicted tree growth and mortality by 2050. Using i-Tree Eco software, …

Using graphs, Dissimilarity Indices, cartographic analysis, and factor analysis, this study confirms aspects of intra-state sectionalism and periodization in election results identified in previous research but finds different characteristics of section and period in voter registrations. In effect this study finds support …

Forced And Unforced Permafrost Changes In The Northern Hemisphere During 1901-2100, Hong Guo

Graduate Theses and Dissertations

Permafrost regions are very sensitive to rapid changes in climate and environment. In recent decades, there has been growing interest to better understand the permafrost degradation over the Northern Hemisphere in the context of human-induced climate change. Understanding permafrost dynamics is not only important for infrastructure but also for environmental protection in cold regions. In-situ permafrost measurements are important for assessing permafrost conditions. However, direct permafrost observations are sparse and asymmetrical in both spatial and temporal coverage. Active layer thickness (ALT) modeling is another approach that can overcome many of these limitations, but the models have large uncertainty in predicting …

Data-Driven Operational And Safety Analysis Of Emerging Shared Electric Scooter Systems, Qingyu Ma

Computational Modeling & Simulation Engineering Theses & Dissertations

The rapid rise of shared electric scooter (E-Scooter) systems offers many urban areas a new micro-mobility solution. The portable and flexible characteristics have made E-Scooters a competitive mode for short-distance trips. Compared to other modes such as bikes, E-Scooters allow riders to freely ride on different facilities such as streets, sidewalks, and bike lanes. However, sharing lanes with vehicles and other users tends to cause safety issues for riding E-Scooters. Conventional methods are often not applicable for analyzing such safety issues because well-archived historical crash records are not commonly available for emerging E-Scooters.

Perceiving the growth of such a micro-mobility …

Shipboard Lidar As A Tool For Remotely Measuring The Distribution And Bulk Characteristics Of Marine Particles, Brian Leigh Collister

OES Theses and Dissertations

Light detection and ranging (lidar) can provide remote estimates of the vertical distribution of optical properties in the ocean, potentially revolutionizing our ability to characterize the spatial structure of upper ocean ecosystems. However, challenges associated with quantifying the relationship between lidar measurements and biogeochemical properties of interest have prevented its adoption for routinely mapping the vertical structure of marine ecosystems. To address this, we developed a shipboard oceanographic lidar that measures attenuation (α) and linear depolarization (δ) at scales identical to those of in-water optical and biogeochemical measurements. The instrument’s ability to resolve the distribution of optical and biogeochemical properties …

Assessing Population Exposure To Coastal Flooding Due To Sea Level Rise, Matthew E. Hauer, Dean Hardy, Scott A. Kulp, Valerie Mueller, David J. Wrathall, Peter U. Clark

Faculty Publications

The exposure of populations to sea-level rise (SLR) is a leading indicator assessing the impact of future climate change on coastal regions. SLR exposes coastal populations to a spectrum of impacts with broad spatial and temporal heterogeneity, but exposure assessments often narrowly define the spatial zone of flooding. Here we show how choice of zone results in differential exposure estimates across space and time. Further, we apply a spatio-temporal flood-modeling approach that integrates across these spatial zones to assess the annual probability of population exposure. We apply our model to the coastal United States to demonstrate a more robust assessment …

How Phantom Networks, Provider Qualities, And Poverty Sway Medicaid Dental Care Access: A Geospatial Analysis Of Manhattan, Destiny Kelley, Shipeng Sun

Publications and Research

Access to general dental care is essential for preventing and treating oral diseases. To ensure adequate spatial accessibility for the most vulnerable populations, New York State mandates a ratio of one general dentist to 2000 Medicaid recipients within 30 min of public transportation. This study employed geospatial methods to determine whether the requirement is met in Manhattan by verifying the online directories of ten New York managed care organizations (MCOs), which collectively presented 868 available dentists from 259 facilities. Our survey of 118 dental facilities representing 509 dentists revealed that significantly fewer dentists are available to treat Medicaid recipients compared …

Nuanced Networks: How Social Relationships And Power Influence Participation In Private Lands Conservation Programs, Ellen Loechner

Geography ETDs

Because the majority of land in the Midwestern United States is privately owned, the responsibility for creating and maintaining space for wildlife conservation falls upon private landowners. Numerous state and federal agencies and non-governmental organizations (NGOs) host private lands conservation programs that offer landowners financial and technical support to complete conservation projects on their property (Echols, Front, and Cummins 2019). While the individual motivations and priorities of a landowner may inform how they use and manage their property, a landowner’s ability to connect with the agricultural and conservation communities may determine if they have the opportunity to participate in these …

Factors Facilitating And Challenges Facing Community-Based Interventions In Improving Antenatal Care In Rural Tanza, Stephen Maluka, Chakupewa J. Mpambije

Journal of Humanities and Social Sciences

The improvement of antenatal care has remained a topical global concern as signalled by maternal deaths, which have remained unacceptably high, especially in low- and middle income countries. In response to this concern, community-based interventions through women’s groups have been implemented to improve antenatal care; and have shown promising results in rural settings. However, factors contributing to the success or failure of these interventions vary across geographical settings, thereby necessitating area specific considerations. This paper sets out to unveil significant facilitators and barriers to the implementation of women’s group interventions in Tanzania. A qualitative case study design was employed involving …

Market-Driven Rice Farming And Water Use Change In Mbarali District From The Mid-1980s To The 2010s, George K. Ambindwile

Journal of Humanities and Social Sciences

This paper examines the effects of market-driven rice farming on the use of water in Mbarali District from about the mid-1980s to 2010s. It specifically traces the development of both peasant and state rice farming and their subsequent effects on water use in the district. The study is essentially qualitative, although in some cases it uses quantitative data to validate its arguments. Thus, it adopts political economy and historical ecology theories to understand changes brought by market-driven rice farming; and the ways peasants struggled to accommodate those changes in their agricultural practices. The area of study included six villages, namely …

Spatial-Temporal Modeling Of Agricultural Water Surface Features In Northeastern Arkansas., Daniel Dewayne Shults

Student Theses and Dissertations

The Mississippi River Valley Alluvial Aquifer (MRVA) has been the primary source of irrigation water in Northeastern Arkansas since the early 1900s. Over time the MRVA water level has declined due to over-pumping of farm wells and water restrictive geology. The aquifer is expected to continue declining but with water conservation strategies in place, this vital resource could be preserved for future farmers. This thesis investigated using remotely sensed data to assess landforms associated with agricultural water conservation across Northeastern Arkansas. The remotely sensed data proved to be useful at creating temporal assessments of pre-existing irrigation reservoirs, identifying new irrigation …

The organization of space through history is a difficult show in terms of research, but pleasant on the side of diachronic knowledge allowing knowledge of the present in order to be able to orient reflection towards the future. If in Morocco geography imposes and history disposes, local characteristics have then contributed to the organization of human groups throughout history. However, in the present time, it is the state institutions that organize the population within the units of territorial division, this is also contracted with competitive private activities in areas made by competition.
