The Geographical (And Almost) Non-Geographical Advantages On Access To Water Resources, Clemir Abbeg Coproski

INSPIRE Student Research and Engagement Conference

Although water scarcity doesn’t sound like a 21st century problem, more than 1.2 million people die every year directly related to the lack of access to safe water. Malnutrition, lack of sanitation, and other diseases can bump those numbers even higher. An interesting question that very few might ask is: what are the causes for the lack of access to water? There are several answers to those questions, and some of them are related to geography and some of them are not, or maybe both.

Shocking: Using Machine Learning Techniques To Nowcast Lightning Strikes From Station Level Data, Michael D. Broussard

LSU Master's Theses

Lightning strikes are incredibly common and potentially hazardous. Lightning can lead to loss of life, property damage, or can trigger other hazardous events like wildfires. They are also the result of incredibly complex physical processes in the atmosphere, making it challenging to predict strikes. However, given the extensive data and robust analytical techniques available, machine learning methods could be used to establish data relationships between lightning strikes and ground-level atmospheric measurements. Such a model could be used to provide any surface-based weather station with a method for predicting incoming strikes, making it easier to avoid the potentially hazardous effects of …

Spatial And Temporal Variations Of Microplastic Concentrations In Portland's Freshwater Ecosystems, Rebecca Talbot, Elise F. Granek, Heejun Chang, Rosemary Wood, Susanne Brander

Geography Faculty Publications and Presentations

While microplastics are a pollutant of growing concern in various environmental compartments, less is known regarding the sources and delivery pathways of microplastics in urban rivers. We investigated the relationship between microplastic concentrations and various spatiotemporal factors (e.g., land use, arterial road length, water velocity, precipitation) in two watersheds along an urban-rural gradient in the Portland metropolitan area. Samples were collected in August, September, and February and were analyzed for total microplastic count and type. Nonparametric statistics were used to evaluate potential relationships with the explanatory variables, derived at both the subwatershed and near stream scales. In August, microplastic concentrations …

Walking (With) The Platform: Bikesharing And The Aesthetics Of Gentrification In Vancouver, Agnieszka Leszczynski

Geography & Environment Publications

This paper engages the increasing significance of urban platforms through the lens of the aesthetics of gentrification, a mode of place-making through the visual commodification of space. We report on ‘walks-with’ platformized bikesharing infrastructure across a selective sample of three Vancouver neighbourhoods, each differently positioned within the urban spatial hierarchy: gentrified Mount Pleasant/South Main, gentrifying Strathcona/Chinatown, and the gentrifiable East Village. Drawing on photographs, reflections, and observations of the visual fields of select bikeshare stations’ surrounds, we theorize that platformized bikesharing materialities (stations and cycles) function aesthetically through dynamics of serialization, which designates how urban platform materialities express a replicated …

Mapping The Impact Of A Trailway System On The Amount Of Trash Present Within Two Watersheds Of Lynchburg City, Virginia, Lillian Smith

Student Scholar Showcase

Transportation of trash debris within water systems is a prominent occurrence which has been linked to natural and artificial processes such as wind, rain, and littering. Recreational areas, such as activities along greenway trails, have been determined to be a source of debris found in waterways. This study examines whether the presence of an established recreational trail system limits trash accumulation in the entirety of a watershed. Trash data collected at Blackwater Creek, which contains an established trail system, was compared to trash data collected at Fishing Creek, containing a non-established trail system, to answer this hypothesis. A distance of …

Site Selection For Norfolk Day Services Facility, Faith N. Witkowski, Hua Liu

College of Arts and Letters Posters

In October 2021, The Center: A Temporary Shelter transitioned from its downtown location to a residential area a few blocks away. After the move, a pressing, geographic-based question has surfaced: what makes the best location for the houseless population to be able to utilize resources? Using two methods, this study endeavored to answer this question in multiple ways, through different lenses. Method one's objectives are to find an optimal location(s) for a potential Norfolk day service facility based on 1) proximity to social and health services, 2) proximity to a neighborhood that would most benefit from a day center, and …

A Tectonic Geomorphic Study Of Neotectonics And Seismic Hazard Of The Fold And Thrust Belt Complex Of Bengal Basin, Eastern Himalayan Range, Niroj Shrestha

Masters Theses & Specialist Projects

Tectonic activity continues to shape and create challenges for human populations in tectonically active areas. The Bengal Basin is one of the most important sedimentary basins of the Eastern Himalayan Range, aiding in one of the densely populated regions of the world. The basin is part of the tectonically active Himalayan Orogen that is undergoing oblique subduction between the Eurasian Plate and the Indian Plate. As a result of this subduction-related convergence, the eastern part of the Basin, particularly the Chittagong-Tripura Fold Belt (CTFB) and western part of the Indo-Burman Range (IBR) has structurally deformed into a series of mostly …

A Remote Sensing And Machine Learning-Based Approach To Forecast The Onset Of Harmful Algal Bloom (Red Tides), Moein Izadi

Dissertations

In the last few decades, harmful algal blooms (HABs, also known as “red tides”) have become one of the most detrimental natural phenomena all around the world especially in Florida’s coastal areas due to local environmental factors and global warming in a larger scale. Karenia brevis produces toxins that have harmful effects on humans, fisheries, and ecosystems. In this study, I developed and compared the efficiency of state-of-the-art machine learning models (e.g., XGBoost, Random Forest, and Support Vector Machine) in predicting the occurrence of HABs. In the proposed models, the K. brevis abundance is used as the target, and 10 …

Interrogating Race And Place-Based Inequities In Hiv And Covid-19, Rohan Khazanchi

EMET Projects

Over the last four years, I have developed a research focus examining the intersections of race, place, and health. My M.D. Honors Thesis reflects a snapshot of these efforts. In this collection of brief research reports, I leverage area-based measures to investigate structural inequities in three contexts: the HIV epidemic in our hyperlocal community, the early stages of the COVID-19 pandemic, and clinical trials for novel COVID-19 therapeutics. I apply novel social epidemiologic tools to measure and explore disparate outcomes. And, in reflecting upon my findings, I discuss concrete implications for clinicians, researchers, and policymakers alike.

Short-Term 2d And 3d Geomorphic Change Detection At A Public Park On Lake Michigan Using Uas Remote Sensing Techniques, Scott Patrick Fitzgerald

Masters Theses

The high-water level of Lake Michigan (LM) in the past few years has led to significant periods of erosion and increased the risk to private property owners on the coast. To cope with this, many property owners on the coast of LM have constructed coastal protections, some opting for seawalls. Previous studies have assessed the effects of seawalls but disagreed on their impacts, and only laboratory studies were able to establish their range of influence. Using a different method to study their effects will be pertinent to understanding them.

This research aims to use a higher temporal and spatial resolution …

Maritime Moves: The American Response To The South China Sea Conflict, Joshua Jachlewski

Senior Honors Theses

China is quickly becoming a world power and will soon reach parity with the United States. China has gotten far more aggressive in its expansion, which extends to the islands within the South China Sea. China claims most of this based on the Nine-Dash Line, in violation of the United Nations Convention on the Law of the Sea. As the current world superpower, the United States must respond to these claims given the geostrategic importance of the region. An analysis of the current Chinese and US positions, as well as those of the other littoral states with competing claims, allows …

Urban Forest Dynamics: Untangling Ecosystem Patterns At Harbison State Forest, Derek Matchette

Theses and Dissertations

As expansion continues to push the wildland-urban interface farther into the suburbs and the landscape which surrounds cities, it will become more important to understand the factors that influence species composition in remaining green spaces. Harbison State Forest, an ~890-hectare urban forest provides a convenient setting to analyze species composition patterns within a multipurpose urban green space.

The factors that can create these patterns include environmental (topography, soil nutrient content, light, temperature, and precipitation), naturally occurring disturbances that alter these factors (e.g., fire, windthrow), and anthropogenic disturbances such as logging and prescribed burning.

I measured basal area by species on …

An Analysis Of Wet Bulb Globe Temperature Estimation Methods And Microclimate Heat Variability In Columbia, South Carolina, Stafford Mullin

Theses and Dissertations

Extreme heat is the leading cause of weather-related deaths in the United States and poses major health risks in the wake of rising global average temperatures. Wet bulb globe temperature (WBGT) is a holistic measure of human heat stress, but is not feasible to implement in most settings because the equipment is expensive and troublesome to operate. This research evaluates the performance of WBGT estimation methods using more standard meteorological variables, measured in-situ and a local National Weather Service Automated Surface Observing Station, and examines how WBGT and its components vary across two distinct microclimates in Columbia, SC. Results indicate …

Suas And Deep Learning For High-Resolution Monitoring Of Tidal Marshes In Coastal South Carolina, Grayson R. Morgan

Theses and Dissertations

Tidal marshes are dynamic environments, now more than ever threatened by both natural and anthropogenic forces. Best practices for monitoring tidal marshes, as well as the environmental factors that affect them, have been studied for more than 40 years. With recent technological advances in remote sensing, new capabilities for monitoring tidal marshes have emerged. One of these new opportunities and challenges is hyper-spatial resolution imagery (<10 >cm) that can be captured by small unmanned aerial systems (sUAS). Aside from enhanced visualization, structure-from-motion (SfM) technology can derive dense point clouds from overlapped sUAS images for high resolution digital elevation models (DEMs). …
