Assessing Beaver Dam Dynamics In The Logan-Little Bear Watershed, Connor Penrod 2019 Utah State University

Assessing Beaver Dam Dynamics In The Logan-Little Bear Watershed, Connor Penrod

All Graduate Plan B and other Reports

This paper seeks to address a knowledge gap concerning how flood events impact beaver dams over time. To address this gap, I took four time-snapshots of beaver dams, mapping them across the Utah portion of the Logan-Little Bear watershed, from 2009 to 2016 to bookend a large flood event in 2011. I assessed dam status (intact, breached, or blown out) for each dam mapped to assess the impact of the large spring runoff on the dam status. Assessing dam status over time allowed me to assess the change in condition over time, from before to several years after, while also ...


Atlanta's Flood Risk: A Model Based On Growth And Climate Change, Kaitlen Martin, Amber Ignatius 2019 University of North Georgia

Atlanta's Flood Risk: A Model Based On Growth And Climate Change, Kaitlen Martin, Amber Ignatius

Georgia Undergraduate Research Conference (GURC)

Climate change poses unique and significant challenges for Georgia’s large and growing cities. Ranked as the second-best city in the United States for millennials, the city of Atlanta and the surrounding region is expected gain 2.5 million people in the next twenty years. Sustainable development strategies to accommodate the combination of changing climate and substantial population growth requires planning beyond simply finding open space. Planners must look to more detailed solutions to mitigate long-term impacts of rapid urbanization within a non-stationary climate. Regions within the city of Atlanta are already prone to flooding during heavy rain events, the ...


Visualization And Quantitation Of Radioiodine Distribution In Silver Zeolite Cartridges, Daniel DiMarco 2019 Louisiana State University

Visualization And Quantitation Of Radioiodine Distribution In Silver Zeolite Cartridges, Daniel Dimarco

LSU Master's Theses

Iodine 131 is a major fission product released during a nuclear incident. This isotope provides a serious health hazard for humans and the environment, therefore nuclear power plants must monitor releases using air sampling. The air sampling is accomplished using air filter cartridges using silver zeolite as a filter media. During an emergency situation, silver zeolite is useful for its affinity to I-131 without adsorbing other radioactive gases. After leaving the plume, these cartridges are counted in a low background area. This measurement does not take into account the distribution of radioiodine in the cartridge. This study explores two methods ...


The Effects Of Erosion Structures On Triplett Creek From The Fall Of 2016, 2017, And 2018, Haylee Winters 2019 Murray State University

The Effects Of Erosion Structures On Triplett Creek From The Fall Of 2016, 2017, And 2018, Haylee Winters

Posters-at-the-Capitol

Triplett Creek is a tributary of the Licking River. It runs through Morehead, KY, where we are conducting our research.

The creek was modified in the 1970s but construction was halted before the project was complete. Unfortunately, the result was an increase in overflow and subsequent riverbank erosion. The city installed sediment trap rocks in hopes of slowing down the water and decreasing erosion. We are using drones and photogrammetric software to map the area and compare images of the river to determine erosion rates. The new images will be compared to ones taken in previous years to visualize the ...

Development of simple, fast and accurate methods for quantification of volatile organic compounds (VOCs) in soil samples is important for providing greater efficiency of analytical laboratories in Kazakhstan and other developing countries. Naphthalene is a model polycyclic aromatic hydrocarbon (PAH), belonging to a group of compounds of significant concern due to environmental impact. Solidphase microextraction (SPME) is an optimal method for solvent-free automated sample preparation for determination of VOCs in environmental samples. In this work, the method for quantification of naphthalene in soil based on headspace SPME, gas chromatography with mass spectrometric detection, and standard addition calibration was developed. The ...

The Disaggreated RSEI model data (also known as RSEI-GM, or Geographic Microdata) version 2.3.4 was downloaded from the Amazon Web Service created by EPA. The RSEI-GM provides detailed air model results from EPA’s Risk-Screening Environmental Indicators (RSEI) model. The results include chemical concentration, toxicity-weighted concentration and score, calculated for each 810 meter square grid cell in a 49-km circle around the emitting facility, for every year from 1988 through 2014. The data can be used to examine trends in air pollution from industrial facilities over time and across geographies. In order to allow for evaluation of toxic-weighted ...


Mercury Concentrations In Bat Guano From Caves And Bat Houses In Florida And Georgia, Amy E. Edwards, Jenise L. Swall, Charles H. Jagoe 2019 Hanover County Government

Mercury Concentrations In Bat Guano From Caves And Bat Houses In Florida And Georgia, Amy E. Edwards, Jenise L. Swall, Charles H. Jagoe

Virginia Journal of Science

Previous studies have indicated that several pollutants are bioaccumulating in insectivorous bats, including the heavy metal mercury. This has resulted in an increased presence of mercury in bat waste (guano). In this study, we collected bat guano from ten caves in Florida and Georgia and two bat houses in Florida and analyzed the samples for mercury concentrations (ppm). Since the predominant bat species using caves (Myotis austroriparius) versus bat houses (Tadarida braziliensis) were different, the objective of this study was to make statistical comparisons of the mercury concentrations among caves, between caves and bat houses, and between bat houses. We ...


Traditional Knowledge Of Fire Use By The Confederated Tribes Of Warm Springs In The Eastside Cascades Of Oregon, Michelle M. Steen-Adams, Susan Charnley, Rebecca McLain, Mark D. O. Adams, Kendra L. Wendel 2019 USDA Forest Service

Traditional Knowledge Of Fire Use By The Confederated Tribes Of Warm Springs In The Eastside Cascades Of Oregon, Michelle M. Steen-Adams, Susan Charnley, Rebecca Mclain, Mark D. O. Adams, Kendra L. Wendel

Institute for Sustainable Solutions Publications and Presentations

We examined traditional knowledge of fire use by the Ichishikin (Sahaptin), Kitsht Wasco (Wasco), and Numu (Northern Paiute) peoples (now Confederated Tribes of Warm Springs, CTWS) in the eastside Cascades of Oregon to generate insights for restoring conifer forest landscapes and enhancing culturally-valued resources. We examined qualitative and geospatial data derived from oral history interviews, participatory GIS focus groups, archival records, and historical forest surveys to characterize cultural fire regimes (CFRs) –an element of historical fire regimes– of moist mixed conifer (MMC), dry mixed conifer (DMC), and shrub-grassland (SG) zones. Our ethnohistorical evidence indicated a pronounced cultural fire regime in ...
