Dam Mormons: Responding To The 1976 Teton Dam Disaster In The "Lord's Way", Lauriann Vaterlaus Deaver
Dam Mormons: Responding To The 1976 Teton Dam Disaster In The "Lord's Way", Lauriann Vaterlaus Deaver
Boise State University Theses and Dissertations
The June 5, 1976, Teton Dam collapse occurred in a unique region of Idaho where the population comprised as much as ninety-five percent of residents belonging to The Church of Jesus Christ of Latter-day Saints. The homogenous nature of this population influenced the nature of the recovery effort following the disaster. The Teton Dam recovery effort provided an opportunity for the LDS church, using its welfare system and priesthood (lay male leadership) organizational structure to seamlessly work with government agencies. Church leaders used the reports of positive interactions between its members and the federal and local leaders to celebrate an …

Paleohydrology And The Origin Of Jewel Cave, Mike Wiles
Paleohydrology And The Origin Of Jewel Cave, Mike Wiles
National Cave and Karst Management Symposium 2013
With more than 267 m (166 miles) of mapped cave passages, Jewel Cave is the third longest cave in the world. The passages are beneath an area of 775 ha (3 mi2), located almost entirely within the Hell Canyon drainage basin. The canyon itself is situated in the bottom of a south-plunging syncline and most of the cave passages are located within the east limb. A down-dip cross section shows the cave passages assuming the shape of an elongate lens, located just below the Pahasapa/Minnelusa contact. The lower boundary is a maximum of 75 m (250 feet) below …

Bioerosive Structures In Orbitolinid Foraminifera: Examples From The Lower Cretaceous Of Central Iran, Felix Schlagintweit, Ioan I. Bucur, Koorosh Rashidi, Behnam Saberzadeh
Bioerosive Structures In Orbitolinid Foraminifera: Examples From The Lower Cretaceous Of Central Iran, Felix Schlagintweit, Ioan I. Bucur, Koorosh Rashidi, Behnam Saberzadeh
Studia UBB Geologia
Lower Cretaceous orbitolinid assemblages from Central Iran yield various bioerosional structures. The omnipresent traces of different boring taxa and groups (e.g., sponges, calcimicrobes, incertae sedis) represent a characteristic feature of the investigated thin-section material. The assemblage can be attributed to the Entobia ichnofacies dominated by borings assigned to the activity of sponges. The boring galleries are often concentrated in a plane parallel to the test surface, along the boundary of the marginal and the central zone of the orbitolinid tests. The borings are observed in foraminiferan-dasycladalean wackestones to poorly washed-out packstones, which can be referred to a subtidal …
Integrated Three-Dimensional Geophysical Analysis Of The Wasatch Fault Zone Near Rock Canyon, Provo, Utah, Leo T. Brown, Dr. Alvin K. Benson
Integrated Three-Dimensional Geophysical Analysis Of The Wasatch Fault Zone Near Rock Canyon, Provo, Utah, Leo T. Brown, Dr. Alvin K. Benson
Journal of Undergraduate Research
The Wasatch fault zone extends from southern Idaho into central Utah, and approximately ninety percent of Utah’s population live in or near this fault zone. Surface rupture and ground shaking associated with earthquake events represent the biggest geologic hazards to people and structures within this fault zone. Movement and rupture will most likely occur along preexisting zones of weakness or faults. In order to mitigate damage to buildings and loss of lives, the locations of individual faults within the fault zone should be determined as accurately as possible.
Critical Success Factors Analysis Of Implementing Mpa At The Yilan Gueishan Island, Taiwan, Ching-Ta Chuang, Jun-Yu Chen, Kuei-Chao Chang, Li-Wen Hung, Ta-Kang Liu
Critical Success Factors Analysis Of Implementing Mpa At The Yilan Gueishan Island, Taiwan, Ching-Ta Chuang, Jun-Yu Chen, Kuei-Chao Chang, Li-Wen Hung, Ta-Kang Liu
Journal of Marine Science and Technology–Taiwan
Gueishan Island, located along the strong Kuroshio current, is one of the most essential fishing grounds in Taiwan’s offshore fishery, and critical during its transitional fishery periods. However, long-term pollution, overfishing and rapid coastal development result in overexploitation and adverse environmental and ecological impacts. Previous studies focused on single species fishery management or merely the interpretation relevant laws whereas the views and perceptions of the stakeholders are often overlooked. Therefore, stakeholders’ participation and co-management seem to challenge the future establishment of a Marine Protected Area (MPA) in Gueishan Island. This study focuses on the evaluation of stakeholders’ perception and analyzes …

Identification Of Pipelines From The Secondary Reflect Wave Travel Time Of Ground-Penetrating Radar Waves, Kun-Fa Lee, Tan-K Wang1, Yu-Ming Kang, Cheng-Sung Wang, Kuo-An Lin
Journal of Marine Science and Technology–Taiwan
When using ground-penetrating radar to identify underground pipelines of similar dielectric constants (i.e. PE and PVC), misidentification is quite common. In this study, we apply reflected travel time of radar waves into the PE- and PVC- dielectric constants and the differentiation becomes possible. We have conducted the experiments using the nonmetal PE- and PVC- pipelines as well as the heavy metal (iron) pipelines in a water environment. Based on a travel- time calculation, the dielectric constants of non-metal pipelines with similar composition (PE = 2.3 and PVC = 3.0) were quite close. The error between the experimental and theoretical values …
Forty Years Of Epikarst: What Biology Have We Learned?, Tanja Pipan, David Culver
Forty Years Of Epikarst: What Biology Have We Learned?, Tanja Pipan, David Culver
International Journal of Speleology
Epikarst is not only an important component of the hydrogeology of karst and an active site of speleogenesis, it is habitat for a number of species adapted to subterranean life. Water in epikarst, with a residence time of days to months, is a highly heterogeneous habitat, and the animals are primarily sampled from continuously sampling dripping water or collecting from residual drip pools. While the subterranean fauna of cracks and crevices has been known for over 100 years, it is only in the past several decades that epikarst has been recognized as a distinct habitat, with reproducing populations of stygobionts. …
Depth To Bedrock Estimations Using The H/V Spectral Ratio In The San Joaquin Valley, Tyler A. Morelli
Depth To Bedrock Estimations Using The H/V Spectral Ratio In The San Joaquin Valley, Tyler A. Morelli
Natural Resources Management and Environmental Sciences
Basin depth is a fundamental parameter in many types of geologic studies such as resource exploration and regional tectonic mapping. The Horizontal-to-Vertical Spectral Ratio (“H/V”) method has been successfully applied to estimating of basin depths up to several hundred meters. In this study the H/V method is applied to the deep basins on the western side of the San Joaquin Valley to determine the thickness of the sedimentary layers and depth to bedrock. Microtremor data from Earthscope Seismic Array stations are ideal to test the accuracy of the H/V method on deeper basins because the data is of high-quality and …

Characterization Of The Northern Hemisphere Glacial Cycle-Ii And Termination From High Resolution Speleothem Isotope And Trace Elemental Time-Series Data, Southwest United States, Zachary Lapointe
Earth and Planetary Sciences ETDs
Absolute dated high-resolution records from two speleothems from the southwestern United States (SW USA) are used to constrain the timing and character of the Penultimate Glacial period (NH Glacial-II) and the following glacial termination (T-II) in the northern hemisphere (NH). Speleothems FS-TR3 from Fort Stanton Cave and CaCa-MSC-3 from Carlsbad Caverns National Park reconfirm the close connection between NH Glacial-II climate changes and NH insolation variation. NH Glacial-II maxima observed in the southwestern United States (SW USA) corresponds with Heinrich Event 11 (HE11) and a weak East Asian (EA) monsoon event observed in southeast (SE) China stalagmites SB11 (Cheng et …

Holocene Evolution In Weathering And Erosion Patterns In The Pearl River Delta, Dengke Hu, Peter D. Clift, Philipp Böning, Robyn Hannigan, Stephen Hillier, Jerzy Blusztajn, Shiming Wan, Dorian Q. Fuller
Faculty Publications
Sediments in the Pearl River delta have the potential to record the weathering response of this river basin to climate change since 9.5 ka, most notably weakening of the Asian monsoon since the Early Holocene (∼8 ka). Cores from the Pearl River delta show a clear temporal evolution of weathering intensity, as measured by K/Al, K/Rb, and clay mineralogy, that shows deposition of less weathered sediment at a time of weakening monsoon rainfall in the Early-Mid Holocene (6.0-2.5 ka). This may reflect an immediate response to a less humid climate, or more likely reduced reworking of older deposits from river …

The Application Of Reflectance Spectroscopy To Chert Provenance Of Mississippian Symbolic Weaponry, Ryan Michael Parish
Electronic Theses and Dissertations Archive
Determination of the source of chert artifacts ties past peoples to specific locations on the landscape either through direct or indirect procurement strategies allowing researchers to visualize interactions with both resources and people. However, due to inherent variability accurate provenance data often remains elusive. The reliance upon chert provenance data obtained through macroscopic techniques is problematic and emphasizes the importance of continued research and development of analytical methods whose aim is the objective characterization of source for archaeological materials manufactured from chert. The following thesis is organized around three primary objectives. The first objective is the investigation of the non-destructive …

pg(s) 393-401 The presence of man-made cavities below the historical parts of towns is a common feature in large portions of Italy. Different typologies of anthropogenic cavities have been excavated in different epochs for many purposes, including research and collection of potable water, establishment of underground working sites for olive oil production, worship sites, etc. Underground quarries are probably the most diffuse typology of subterranean cavities, especially the largest ones. Originally located at the outskirts of towns, quarries are increasingly found in built up areas due to urban expansion that has characterized the last century. This paper describes the recent …

pg(s) 27-36 Karst can cause a litany of problems for a windpower project, and it is good practice to evaluate karst risk before proceeding with a proposed project. Windpower projects involve widely-spaced structures with small footprints that can cost $2 million to $5 million each. Financial viability can prove difficult, so it is important to find useful, inexpensive procedures for evaluating karst risk. The karst-risk-review process we have used can be split into the two categories outlined below. Desktop studies: * Search for relevant literature * Review aerial-photo and map, and analyze lineament * Search for existing well and boring …

Nutrient Contribution Of The Shallow Unconfined Aquifer To Pineview Reservoir, Thomas Nyanda Reuben
Nutrient Contribution Of The Shallow Unconfined Aquifer To Pineview Reservoir, Thomas Nyanda Reuben
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Pineview Reservoir, near Utah’s populous Wasatch Front, could play an important role in modulating water supply as water demands and water uses change in response to increasing population densities. The reservoir’s water quality may decline if nitrogen and phosphorus additions to the reservoir are not controlled. Most of the water flowing into the reservoir in summer and fall is contributed by the shallow ground water. The quantity and quality of the shallow ground water to Pineview Reservoir were studied from February 2010 through November 2011. The objectives were to: 1) increase understanding of nitrogen and phosphorus transport from ground water …
Comprehensive Analysis Of An Ongoing Co2 Storage Project, Daniel Moreno
Comprehensive Analysis Of An Ongoing Co2 Storage Project, Daniel Moreno
Graduate Theses, Dissertations, and Problem Reports (ETD)
Increase in CO2 emission has become an important issue over the years due to its environmental impacts as a greenhouse gas. The fact that these emissions are primarily derived from energy consumption and that 85% of the primary power is supplied by fossil fuels (Orr, 2004), makes the reduction of CO2 emissions a major challenge. CO2 sequestration in the geological formations has been identified as an alternative to counter the impact of the emissions. CO2 sequestration refers to the capture and long term storage of CO2.;In order to properly asses the viability of CO2 sequestration in a geological formation as …

Earthquake Petrology: Linking Fault-Related Deformation To The Earthquake Cycle, Mitchell R. Prante
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Faults have a controlling influence on a variety of geologic processes including fluid flow, the mechanical behavior of the crust, and seismicity. The geologic sciences have long recognized that faults generate earthquakes; however, few indicators of ancient earthquakes exist in fault-zones. This dissertation documents several indicators for the preservation of ancient earthquakes in fault-zones including frictional melt (pseudotachylyte), highly-polished fault slip surfaces, and hydrothermal alteration.
These deformation products result from rapid generation of frictional heat during earthquakes. This dissertation also focuses on the seismic potential of continental low-angle normal faults (LANF). We document the preservation of voluminous pseudotachylyte along a …
