Flood Resilience Assessment Of New Orleans After Hurricane Katrina Based On Thermal And Vegetation Index Image Time Series, Yirui Deng

LSU Master's Theses

Resilience is a concept with increasing importance in modern risk management because of its role in reducing risks of unpreventable disasters. Previous resilience assessment studies often require extensive surveys of various social, economic, and psychological data or incorporate remote sensing data as one of the complicated physical and social parameters for assessment models. Limited data accessibility to such data due to funding, time, and labor intensity is a major challenge for their wider applications. Therefore, this study proposes the hypothesis that the overall resilience of an urban area to disturbances of natural disasters can be reflected through the time series …

Climatology, Variability, And Return Periods Of Tropical Cyclone Strikes In The Northeastern And Central Pacific Basins, Nicholas S. Grondin

LSU Master's Theses

Tropical cyclones (TCs) are among the most destructive meteorological phenomena and impact the lives of people who reside along the coast. The American Pacific Coastline borders the second most active TC development region in the world, the northeastern Pacific (NE Pac) basin. This region, along with the Central Pacific (C Pac)-bordering Hawaii is home to a growing population and cities engaged in a variety of economic activities, most prominently agriculture, fishing, and tourism. This study analyzes fifty-two (1966-2017) years of NE Pac and C Pac TCs through applying track data from the National Hurricane Center’s HURDAT2 and a TC size …

Surface Gravity Waves In The Gulf Of Mexico And Their Role In Ocean-Atmosphere Coupling, Ehsan Abolfazli

LSU Master's Theses

This study provides an overview of the surface gravity wave dynamics in the Gulf of Mexico (GoM) using numerical simulations. The focus is on the effects of ocean currents on waves, and the geographic distribution of a set of wave statistics and parameters related to the role of waves on both sides of the ocean-atmosphere interface. Simulations are performed using the Simulating WAves Nearshore (SWAN) model with and without coupling with the Regional Ocean Modeling System (ROMS) model within the Coupled Ocean Atmosphere Wave Sediment Transport (COAWST) framework. In the GoM, currents alter the climatological significant wave heights (H …

The Garbage That We Eat: Metabolizing Food-Waste In New Orleans, Louisiana, Kelly L. Haggerty

LSU Master's Theses

The 2017 Climate Action for a Resilient New Orleans report strives to divert 50 percent of waste by 2030. In the same year, waste companies had only managed to divert 5 percent of the total annual waste in Orleans Parish. Nearly a decade away from 2030, city officials have not even tested or implemented strategies to reach this goal. While city officials scramble to launch pilot projects, community and grassroots organizations center around recovering and transforming garbage and food waste. Using interviews and surveys with food-waste organizers from May to August 2018, this paper reveals that managing food-waste on a …

Reflector Dip Trends In Seismic Sh-Wave Imaging Of A Modern Lower Mississippi River Point Bar, Adam Gostic

LSU Master's Theses

Various studies of ancient point bars have noted that a relationship can be observed between the dip angle and grain size of point bar lateral accretion deposits, with the most mud-rich deposits tending to exhibit the greatest dip. No analysis and only cursory explanations for this relationship have been provided. Additionally, buried mid-channel bars are absent from typical models of point bar architecture.

We successfully image the architecture of late-stage point bar deposits with a near surface 2D seismic SH-wave reflection survey and generate an SH-wave velocity model of the subsurface in the study area in order to interpret the …

Downscaling Smap Soil Moisture Data Using Modis Data, Le Tu

LSU Master's Theses

Soil moisture level is an important index in studying environmental changes. High resolution soil moisture data is in high demand for agricultural and weather forecasting purpose. Current daily large-scale soil moisture projects fail to provide sufficient resolution for medium or small region research. To acquire high-resolution soil moisture data, different kinds of methods are put into practice, including multivariate statistical regression, weight aggregation and so on. In this research, SMAP (Soil Moisture Active Passive) level 3 data with 36-km resolution are successfully downscaled by MODIS (Moderate Resolution Imaging Spectroradiometer) 1-km LST (Land Surface Temperature) product, NDVI (Difference Vegetation Index) product, …

This thesis covers the Brooklyn Museum of Art’s “Graffiti” show in 2006, Los Angeles’s Museum of Contemporary Art’s “Art in the Streets” in 2011, and the 2012-2015 activities of the Baton Rouge Museum of Public Art. These events offer a chronological and geographical range to provide a broad scope of investigation into the pitfalls and opportunities of museum’s exhibiting graffiti and street art. The heart of this research is not to prolong the debate about whether museums endanger their authority when …

An Evaluation Of The Utility Of A Mass-Weighted Frequency Distribution Of Sediment For Modeling Aeolian Transport Rates, Raihan Jamil

LSU Master's Theses

Predictions made by aeolian transport models often do not match well with measured data. The poor predictive capability of these models remains a fundamental problem in aeolian geomorphology. This study evaluates the effectiveness of the recently proposed mass-weighted frequency distribution (Edwards and Namikas 2015) and the apparent von Kármán parameter proposed by Li et al. (2010) to improve transport rate predictions. The evaluation consists of comparisons of predicted transport rates versus a large dataset of measured field and lab transport rates collected from the literature. The transport rate predictions are made both with and without recalibration of model empirical coefficients. …

"If You Stand On This Corner, People Know What You're About": Powerful Geographies Of Airline & Goodwood In #Justiceforalton, Shannon Kathleen Groll

LSU Master's Theses

This thesis seeks to understand the multiple geographies of Airline & Goodwood, a site of protest occupied nightly during a part of summer 2016 in response to the police shooting of Alton Sterling. Through a methodology of observant-participation, interviews, and oral histories, I make the case that the politics of this site differed from other contemporaneous protest sites in the city through specific place-making activity which highlighted the site’s powerful contemporary and historical geographies. I connect protest at this site to the precarity of Black life and death in Baton Rouge through interviews and oral histories which discuss the historical …

Construction Of A Tropical Cyclone Size Dataset Using Retroactive Analysis Data With A Damage Application, Derek Trent Thompson

LSU Master's Theses

This thesis introduces a new tropical cyclone (TC) size dataset. Using the radius of the outermost closed isobar (ROCI) as the size metric of focus, a comprehensive record of TC size at landfall was constructed for tropical storms and hurricanes that made landfall in the United States along the East Coast and in the Gulf of Mexico. The ROCI information was derived from mean sea level pressure maps generated using the NCEP/NCAR Reanalysis I dataset over a 69-year period (1948 – 2016). Construction of the dataset involved using two methodologies, one based on hourly interpolated HURDAT2 best tracks and the …

Understanding “Southern” Identities And Confederate Iconography: Internal Orientalism, (Mis)Representation, And Social Media, Robert W. Perham

LSU Master's Theses

In light of recent debates surrounding Confederate iconography (flags, statues and symbols), this thesis has three foci. First, the continued construction of the American “South” as an internal “Other.” Second, the reactive perspectives taken by self-identifying “Southerners” who both support and denounce Confederate iconography. Third, the role that social media platforms (Facebook, Twitter and Instagram) have as sites that both disseminate hegemonic discourse and facilitate resistance. Drawing on a Foucauldian discourse analysis of content (news articles, posts, videos, images, memes) published and discussed on social media, I explore whether "the South" continues to be portrayed as a lesser "Other" nationally, …

A Novel Multiproxy Approach To Reconstructing Sea Surface Temperature In The Southwestern Gulf Of Mexico, Marissa Anne Vara

LSU Master's Theses

Coral Sr/Ca is a widely-used proxy for sea surface temperature (SST); however, discrepancies in the coral Sr/Ca-SST relationship among colonies of the same species makes uncertainty in absolute temperature reconstructions larger than the climate signal yet climate variability studies are possible. Furthermore, the riverine input of terrestrial carbonate weathering products to the coastal waters can disrupt the coral Sr/Ca-SST signal by changing local seawater chemistry. This study evaluates the fidelity and reproducibly of coral SST proxies (Sr/Ca, Li/Ca, Mg/Li, Sr-U, Mg/Ca, and U/Ca) and a riverine-upwelling proxy (Ba/Ca) in four Orbicella faveolata colonies in two reefs offshore from Veracruz, Mexico …

Stratigraphic Reconstruction Of A Late Pleistocene Bald Cypress Forest Discovered On The Northern Gulf Of Mexico Continental Shelf, Suyapa Michell Gonzalez Rodriguez

LSU Master's Theses

A previously buried bald cypress forest (Taxodium distichum) was discovered on the continental shelf, offshore of Orange Beach, Alabama, USA, in ~20 m water depth. The forest was exhumed by Hurricane Ivan in 2004, and is now exposed as stumps in life position in a trough located in the northern Gulf of Mexico continental shelf seafloor. We are investigating the local stratigraphy, paleo-landscape, and mode of forest preservation of this unique site. In August 2015 and July 2016, submersible vibracores (18 in total) were collected. Core analysis included: bulk density and imaging via Geotek multi sensor core logger, …

Incremental Landscape At A Baton Rouge Oil Refinery: Temporal Framework For Phytoremediation In Louisiana Cancer Alley, Dahyung Yang

LSU Master's Theses

There is a rising need for clear guidance for phytoremediation applications in contaminated land, in anticipation of the severity of the pollution problem in the petrochemical industrial area. Results of a demographic survey of Louisiana neighborhoods adjacent to petrochemical plants indicated that both deep-rooted environmental issues and social inequity are an inherent part of many communities. This research simulated a temporal framework for incremental landscape at a Baton Rouge oil refinery and its surrounding neighborhood using phytoremediation principles with local plants and insects. Through this novel ecosystem, the site will become biodiverse, and community members will be able to explore …

Metacarpal Ratio And Its Relation To Sexual Dimorphism In Primates With Different Mating Strategies, Emilee Hart

LSU Master's Theses

The digit ratio (2D:4D) is a sexually dimorphic trait in mammalian hands that is a result of levels of prenatal androgen exposure (PNAE) during limb development. Previous studies have shown that females have a higher ratio than males and that sexual dimorphism in the ratio is greater in species with polygynous mating strategies and high levels of intermale aggression compared to monogamous species with low intermale aggression. This study used metacarpals instead of phalanges to test the hypotheses that the metacarpal ratio (2Mc:4Mc) will be higher in females than males within a species and that the ratio would be more …

LSU Master's Theses

This thesis studies Iranian student immigrants in the United States in the special political tensions between the two countries from 2000 until present. This research provides a holistic view of understanding the new identity which Iranian students have reconstructed at the intersection of Iranian culture and U.S. culture through their past identity in confronting a new situation. It describes how Iranian students use individual, intellectual, and social resources to deal with the ignorance was that imposed on them when the governments of the two countries began to fight each other to achieve more political power. Data is collected from three …

Press To Stop, Garrett Duncan Hazelwood

LSU Master's Theses

In the wake of a performance art piece in which the audience kills one of the performers and maims the other, the surviving artist is put on display in art galleries by his family. The public clamors to see him, protests against his exploitation rock the city, and intrigue surrounds his sudden rise to fame. In the end, a religion is founded in his honor and his best friend must make a terrible choice about whether or not to save him.

Relating Diets And Food Availability To Long-Term Population Trends Of Lesser Scaup Wintering On Lake Pontchartrain, Louisiana, Clay Michael Stroud

LSU Master's Theses

Lake Pontchartrain provides wintering habitat for a continentally-significant proportion of lesser scaup (Aythya affinis). Mid-winter aerial surveys indicate dramatic variation in annual scaup abundance (0–1,194,907), though the mechanisms driving fluctuations have not been previously investigated. In response to natural and anthropogenic disturbances, species composition, abundance, and size structure of benthic invertebrate populations in Lake Pontchartrain exhibit drastic variability among years. Given that wintering scaup feed primarily on mollusks, environmental disturbances have the potential to influence scaup dynamics on the estuary by altering the benthic community. To diagnose trophic linkages and variation in scaup abundance, we collected ducks (n=60) …

Preservation And Reformation, Yedi Zhang

LSU Master's Theses

ABSTRACT Taking the conservation and development of the Old Town of Luoyang as an example, this thesis explores the issue of largescale renovation and reconstruction of old city in the background of urbanization, and attempts to seek the balance between old town preservation and local residents’ life quality enhancement. It is needing to be aware that, as a result of the layering and intertwining of cultural and natural values over time, the urban historical heritage includes both tangible and intangible components. To protect historical heritage in the city, we should not only just imitate the history scenes, more importantly, it …

An Index For Measuring Community Resilience To Flooding In Baton Rouge, Louisiana, Yi Ling Chan

LSU Master's Theses

The greater Baton Rouge area in Louisiana has been impacted by repeated floods throughout its history. The most recent flood in August 2016 resulted in damages to over 80,000 homes and businesses and upwards of $430 million in public assistance granted by the Federal Emergency Management Agency. East Baton Rouge Parish and neighboring Livingston and Ascension parishes are expected to face compounded pressures and risks with the threat of increasing frequency of flood events coupled with expanding populations due to continuing suburbanization and inland migration from those living on Louisiana's coast. The purpose of this research is to create and …

Rebel Governance In Civil War: Variations In Rebel Governance - A Case Study Analysis., Harriet Ann Sellers

LSU Master's Theses

Insurgent groups vary in how they interact with civilians. Some insurgent groups perform government functions to further their political objectives during civil war, whilst other rebel groups use solely violent means. Why do some insurgent groups perform governance functions to further their political objectives, whilst others interact very little with the local population? I seek to explain the variation in rebel governance, which I argue is motivated by the objective of the insurgency. More specifically, I argue that secessionist insurgencies are more likely to implement governance structures than non-secessionist insurgent groups. Using an in-depth case study analysis, I found varying …

Operational Impact Of Shadow Evacuation On Regional Road Networks During Short-Notice Emergency Evacuations, Efe Emre Tuncer

LSU Master's Theses

As part of evacuation planning, development of effective tactical and operational strategies are essential to safely and efficiently mobilize the public away from the threat. Evacuations are classified by the time between notification and the anticipated arrival of the threat which can be categorized as short, or no-notice emergencies. Emergencies involve the computation of the time required to evacuate the area of risk, which is the time to clear a radius of up to about 10-miles around the nuclear power plant, known as the emergency planning zone (EPZ). These evacuation time estimates (ETE) also account for the evacuation of the …

Analysis Of Marine Sediment By Chemical Signatures And Loss-On Ignition To Discover Evidence Of Ancient Maya Activities At Site 74, Paynes Creek Salt Works, Belize, Kobi Weaver

LSU Master's Theses

In this thesis, archaeological sediment chemistry, loss-on ignition and microscopic analysis of marine sediment are used to study Site 74 of the Paynes Creek Salt Works in southern Belize. Site 74 was once an ancient Maya salt work. Due to sea-level rise, sea water and mangrove peat now cover the site. Sediment from the site was exported under permit to the Louisiana State University Laboratory. I prepared and delivered the samples to the Louisiana State University Agricultural Chemistry Laboratory for inductively coupled plasma- atomic emission spectroscopy testing (ICP-AES). ICP-AES measured the amount of 20 elements in the sediment. Maps showing …

Topographic Control On Post-Lgm Groundings Of The West Antarctic Ice Sheet In The Whales Deep Basin, Eastern Ross Sea, Matthew Danielson

LSU Master's Theses

By the peak of the Last Glacial Maximum (LGM), the West Antarctic Ice Sheet (WAIS) had advanced to the outer continental shelf of eastern Ross Sea trough basins. During the post-LGM retreat, the WAIS paused several times within 75 km of the Whales Deep Basin (WDB) shelf edge. An overlapping stack of seven grounding zone wedges (GZWs) records the locations of these groundings. Here we used ~7500 km of seismic reflection data to map the subglacial unconformity that was eroded when WAIS was grounded at the shelf edge, i.e., prior to the deposition of the backstepping GZWs. With respect to …

Providing Information And Public Outreach Across Three U.S. State Archaeology Offices During The Age Of Open Access, Samuel Thomas Ayers

LSU Master's Theses

Archaeology in the United States has been transformed into a mainstream, practical science over the past fifty years by Cultural Resource Management (CRM) and the federal regulations imposed by the National Historic Preservation Act (NHPA) of 1966. However, this form of archaeology has been plagued with criticisms since the NHPA’s enactment including issues of access and use of data maintained by state site files. State archaeology is publicly funded yet state and federal legislation often exempts CRM data from freedom of information laws. To mitigate this contradiction and stem the growing body of “gray literature”, new open-access (OA) technologies are …

Investigation Of Morphological Changes In Small Coastal Rivers During Flood, Tanzina Afrin

LSU Master's Theses

The delivery of fluvial sediment to coastal margins is one of the major concerns for river and coastal morphodynamics. Relevant research has primarily focused on large rivers that transport substantial sediment load and thus are responsible for building deltaic landscapes. However, less research is concentrated on small coastal rivers. A need exists to better understand the sediment dynamics in small coastal rivers that have different backwater regimes than their larger counterparts. The main objective of this research was to examine the influence of backwater on the morphodynamics of a small coastal meandering river during a large flood event. The investigation …

Evolution Of The Maximum Upper Level Divergence Field In Gulf-Atlantic Tropical Cyclogenesis, Sara A. Ates

LSU Master's Theses

Upper-level (horizontal) divergence (ULD) is an important variable in tropical weather systems. As part of the circulation within a tropical cyclone (TC), it carries air in the upper troposphere away from the center of circulation (COC). To date, most research assumes the 200 hPa pressure level (approximately 12 km, varying with latitude and time of year) as the height for maximum ULD in a TC, possibly because weather observation at the 200 hPa level by radiosonde have remained mandatory for aviation purposes. The more recent availability of gridded, high-spatial-resolution, global “reanalysis” data at multiple levels, along with improvements in spatial …

Scaling Relationships Between Cranial Morphological Features And Cranial Capacity In Modern Humans, Jacob Jesch

LSU Master's Theses

Certain cranial morphologies referred to here as “cranial predictor features” are known to allometrically scale with body mass at statistically significant levels. Brain size likewise is known to scale with body mass, with brain-to-body-mass ratio being expressed numerically via the encephalization quotient. The study at hand aims to demonstrate whether brain size via its skeletal proxy of cranial capacity also scales with cranial predictor features. Correlation analysis was employed on two samples of contemporary male and female modern humans, respectively, in order to determine the statistical significance and degree of association between cranial predictor features and cranial capacity, as well …

Examining Limestone Use At Byrd Hammock South (8wa30), Wakulla County, Fl, Lucie R. Berryhill

LSU Master's Theses

In this thesis, I examine the limestone deposits identified at Byrd Hammock South during the Summer 2015 excavations conducted by Louisiana State University (LSU) and Florida State University (FSU). The site under investigation is the Byrd Hammock site (8WA30) in Wakulla County, Florida. Byrd Hammock is a multi-component site located only four miles north of the Gulf Coast and is close to other Swift Creek sites including Block-Sterns (8LE484) and Harrison Ring (8BY1359) (Russo, Hadden, and Dengel 2009). Like several other sites or site complexes on the Florida panhandle, Byrd Hammock has two large burial mounds that were placed on …
