Modern Fair-Weather And Storm Sediment Transport Around Ship Island, Mississippi: Implications For Coastal Habitats And Restoration Efforts, Eve Rettew Eisemann 2016 University of Southern Mississippi

Modern Fair-Weather And Storm Sediment Transport Around Ship Island, Mississippi: Implications For Coastal Habitats And Restoration Efforts, Eve Rettew Eisemann

Master's Theses

The Mississippi – Alabama barrier island chain is experiencing accelerated sea level rise, decreased sediment supply, and frequent hurricane impacts. These three factors drive unprecedented rates of morphology change and ecosystem reduction. All islands in the chain have experienced land loss on the order of hectares per year since records began in the 1840s. In 1969, Hurricane Camille impacted as a Category 5, breaching Ship Island, and significantly reduced viable seagrass habitat. Hurricane Katrina impacted as a Category 3 in 2005, further widening Camille Cut. To better understand the sustainability of these important islands and the ecosystems they support, sediment transport ...


Surface Water Infiltration In Loess Soils Of The Lower Mississippi River Valley: An Emphasis On Land Use, Matthew Thompson 2016 University of Arkansas, Fayetteville

Surface Water Infiltration In Loess Soils Of The Lower Mississippi River Valley: An Emphasis On Land Use, Matthew Thompson

Crop, Soil and Environmental Sciences Undergraduate Honors Theses

The Alluvial Aquifer is the shallowest and most heavily used groundwater aquifer in the Lower Mississippi River Valley, particularly in the Delta region of eastern Arkansas. However, the Alluvial Aquifer is being depleted faster than the rate of recharge, primarily due to excessive withdrawals for irrigated crop production. Since extensive irrigation in the highly agriculturally productive Delta region of eastern Arkansas has been a main culprit in the groundwater depletion issues the region faces, a better understanding of how ecological factors and/or agricultural best management practices could possibly increase infiltration, to consequently increase recharge, are needed in order to ...


Predicting Post-Fire Change In West Virginia, Usa From Remotely-Sensed Data, Michael Strager P. Strager, Melissa Thomas-Van Gundy, Aaron E. Maxwell 2016 West Virginia University

Predicting Post-Fire Change In West Virginia, Usa From Remotely-Sensed Data, Michael Strager P. Strager, Melissa Thomas-Van Gundy, Aaron E. Maxwell

Journal of Geospatial Applications in Natural Resources

Prescribed burning is used in West Virginia, USA to return the important disturbance process of fire to oak and oak-pine forests. Species composition and structure are often the main goals for re-establishing fire with less emphasis on fuel reduction or reducing catastrophic wildfire. In planning prescribed fires land managers could benefit from the ability to predict mortality to overstory trees. In this study, wildfires and prescribed fires in West Virginia were examined to determine if specific landscape and terrain characteristics were associated with patches of high/moderate post-fire change. Using the ensemble machine learning approach of Random Forest, we determined ...

Artificial Recharge In The Las Vegas Valley: An Operational History, Michael Johnson, Erin Cole, Kay Brothers 2016 Selected Works

Artificial Recharge In The Las Vegas Valley: An Operational History, Michael Johnson, Erin Cole, Kay Brothers

Michael Johnson

Artificially recharging the Las Vegas Valley (Valley) ground-water system with treated Colorado River water is one water resource management option employed by the Las Vegas Valley Water District (District) to help meet future long-term and short-term peak water demands. The District began operation of an artificial ground-water recharge program in 1988 in order to bank water for future use and to slow declining water levels. Artificial recharge occurs in the winter months, typically from October to May, when there is excess capacity in the Southern Nevada Water System (SNWS), currently a 400 Million Gallon per Day (MGD) treatment and transmission ...


Quantifying Early-Seral Forest Composition With Remote Sensing, Rayma a. Cooley, Peter T. Wolter, Brian R. Sturtevant 2016 United States Forest Service

Quantifying Early-Seral Forest Composition With Remote Sensing, Rayma A. Cooley, Peter T. Wolter, Brian R. Sturtevant

Peter Wolter

Spatially explicit modeling of recovering forest structure within two years following wildfire disturbance has not been attempted, yet such knowledge is critical for determining successional pathways. We used remote sensing and field data, along with digital climate and terrain data, to model and map early-seral aspen structure and vegetation species richness following wildfire. Richness was the strongest model (RMSE = 2.47 species, Adj. R2 = 0.60), followed by aspen stem diameter, basal area (BA), height, density, and percent cover (Adj. R2 range = 0.22 to 0.53). Effects of pre-fire aspen BA and fire severity on post-fire aspen structure and ...

Spatial data on soils, land use, and topography, combined with knowledge of conservation effectiveness, can be used to identify alternatives to reduce nutrient discharge from small (hydrologic unit code [HUC]12) watersheds. Databases comprising soil attributes, agricultural land use, and light detection and ranging–derived elevation models were developed for two glaciated midwestern HUC12 watersheds: Iowa’s Beaver Creek watershed has an older dissected landscape, and Lime Creek in Illinois is young and less dissected. Subsurface drainage is common in both watersheds. We identified locations for conservation practices, including in-field practices (grassed waterways), edge-of-field practices (nutrient-removal wetlands, saturated buffers), and ...

Agenda: Flpma Turns 40, University Of Colorado Boulder. Getches-Wilkinson Center For Natural Resources, Energy, And The Environment

FLPMA Turns 40 (October 21)

The Bureau of Land Management (BLM) administers approximately 245 million acres of our public lands and yet, for most of our nation's history, these lands seemed largely destined to end up in private hands. Even when the Taylor Grazing Act of 1934 ushered in an important era of better managing public grazing districts and "promoting the highest use of the public lands," such use of our public lands still was plainly considered temporary, "pending its final disposal." It was not until 1976 with the passage of the Federal Land Policy and Management Act (FLPMA) that congress adopted a policy ...

Cache Water District: Risks And Opportunities. Research And Policy Analysis Report On Formation Of A Water Conservancy District In Cache County, Utah., Lisa W. Welsh, Joanna Endter-Wada

Joanna Endter-Wada

Executive Summary
 
In the November 2016 election, Cache County residents will vote on Proposition #11, Formation of the Cache Water District. The question before voters is: Should the Cache Water District be created? Voters can respond “yes” or “no.”
 
The Cache County Water Master Plan was released in 2013. Discussion and analysis conducted through that planning effort suggested that a water conservancy district would be the best organizational structure for Cache County and its municipalities to collectively and cooperatively manage water. Cache County created the Bridgerland Water Conservancy Work Group (BWC Work Group) to draft a purpose statement and bylaws ...


Uncertainty Analysis Of The Performance Of A System Of Best Management Practices For Achieving Phosphorus Load Reduction To Surface Waters, Jason D.M. Igras 2016 The University of Western Ontario

Uncertainty Analysis Of The Performance Of A System Of Best Management Practices For Achieving Phosphorus Load Reduction To Surface Waters, Jason D.M. Igras

Electronic Thesis and Dissertation Repository

The repeated occurrence of Lake Erie’s harmful algal blooms suggests an inadequate phosphorus management system that results in excessive loads to the lake. In response, Canadian and United States’ governments have issued a new management objective, a 40% reduction in phosphorus loads relative to 2008. To provide scientific evidence to guide managers toward achieving their management objective, we used the International Standard of Organization (ISO) 31010 Bowtie Risk Analysis Tool to analyze the performance of the phosphorus management system. The effectiveness of agricultural best management practices (BMPs) and their adoption were combined into a Bayesian belief network model to ...

A Mi’Kmaw Perspective On Advancing Salmon Governance In Nova Scotia, Canada: Setting The Stage For Collaborative Co-Existence, Shelley K. Denny, Lucia M. Fanning 2016 Dalhousie University

A Mi’Kmaw Perspective On Advancing Salmon Governance In Nova Scotia, Canada: Setting The Stage For Collaborative Co-Existence, Shelley K. Denny, Lucia M. Fanning

The International Indigenous Policy Journal

Issues related to fisheries governance are a source of debate and tension between the Indigenous Mi’kmaq people of Nova Scotia and the Canadian Department of Fisheries and Oceans (DFO) in matters concerning Atlantic salmon, Salmo salar. Within the context of the existing governance regime, this analysis compares the concept of salmon conservation and management from a Mi’kmaq perspective and proposes a collaborative co-existence approach for effective salmon governance in Nova Scotia. This approach begins by using co-management as a process, Two-Eyed Seeing as the design, and treaties as the model to achieve shared objectives of maintaining and improving ...


Prioritizing Investment In Residential Energy Efficiency And Renewable Energy: A Case Study For The U.S. Midwest, Robert J. Brecha, Austin Mitchell, Kevin P. Hallinan, J. Kelly Kissock 2016 University of Dayton

Prioritizing Investment In Residential Energy Efficiency And Renewable Energy: A Case Study For The U.S. Midwest, Robert J. Brecha, Austin Mitchell, Kevin P. Hallinan, J. Kelly Kissock

J. Kissock

Residential building energy use is an important contributor to greenhouse gas emissions and in the United States represents about 20% of total energy consumption. A number of previous macro-scale studies of residential energy consumption and energy-efficiency improvements are mainly concerned with national or international aggregate potential savings. In this paper we look into the details of how a collection of specific homes in one region might reduce energy consumption and carbon emissions, with particular attention given to some practical limits to what can be achieved by upgrading the existing residential building stock. Using a simple model of residential, single-family home ...


Commentary: Are National Parks Still Relevant?, Randall K. Wilson 2016 Gettysburg College

Commentary: Are National Parks Still Relevant?, Randall K. Wilson

Environmental Studies Faculty Publications

On the occasion of the National Parks centennial comes an irreverent question: Are the parks still relevant?

Famously christened as America's "best idea" by writer Wallace Stegner and reaffirmed in Ken Burns' 2009 PBS documentary, it seems brazen, if not blasphemous, to pose the question. [excerpt]


A Landscape Approach To Determining And Predicting Juvenile Coho Salmon (Oncorhynchus Kisutch) Movement Timing And Growth Patterns Prior To Ocean Entry, Amelia Lee Johnson 2016 Portland State University

A Landscape Approach To Determining And Predicting Juvenile Coho Salmon (Oncorhynchus Kisutch) Movement Timing And Growth Patterns Prior To Ocean Entry, Amelia Lee Johnson

Dissertations and Theses

Coho salmon (Oncorhynchus kisutch) rely on unique habitats during the winter season, which may dictate how much individuals may growth and when migration from freshwater rearing habitat to the ocean occurs. Here I analyze movement timing and growth patterns for coho salmon through a field-based study and a literature review. For the field portion, I examined hatchery-stocked juvenile coho salmon across four stream basins in the Russian River watershed, California to determine the relative importance of climate, landscape, and fish size metrics in predicting movement and growth patterns over a winter rearing and spring smolt outmigration time period (December 2014-June ...

How Do Connection And Hopeful Action Support Resilient Community?, Catherine Gormley 2016 SIT Graduate Institute

How Do Connection And Hopeful Action Support Resilient Community?, Catherine Gormley

Capstone Collection

This capstone arises from the course, Initiatives in Peacebuilding (IPB). As a graduate student focusing on Peacebuilding and Conflict Transformation, IPB was a required course whose content propelled me toward the study of resource conflicts. Advancing from that study, I chose to practice strategies to lessen these conflicts by means of positive action. Facing two challenges—that Earth’s natural resources are finite and that excessive use of fossil fuels has caused destructive climate change—I wondered how to help transform human awareness to value the conservation of resources and the abatement of climate change. My research brought me to ...
