Unearthing Complexity: Tangible Histories Of Water And Earth, Alexis Violet
Unearthing Complexity: Tangible Histories Of Water And Earth, Alexis Violet
Masters Theses
Unearthing Complexity investigates conceptions of time and surface through geological stories of the water and earth. Building on theories of deep time, hydrofeminism, critical zones, and grounding, I hope to foster a deeper awareness of time scales other than our own and a more tangible understanding of the embodied experience of matter in the universe. Working toward a new literacy of the water and earth in which they are recognized as living, changing bodies to which we are inherently tied at a molecular level, the site of this multiscalar inquiry occurs in the coastal zones of the Narragansett Bay where …
Challenges In Approaching The Detection Limits For Hillslope Erosion Using Terrestrial Laser Scanning, Gene Nathan Bailey Iii
Challenges In Approaching The Detection Limits For Hillslope Erosion Using Terrestrial Laser Scanning, Gene Nathan Bailey Iii
Masters Theses
Accurately quantifying soil loss due to water erosion is a critical step in managing soils. Terrestrial LiDAR (Light Detection and Ranging) presents a potential alternative to traditional soil loss measurement by estimating soil erosion and deposition through detecting surface changes. Terrestrial LiDAR can also provide spatial distribution information without disturbing the observed surface. While erosion estimation through terrestrial LiDAR detects large magnitude erosion well, the finer temporal/spatial scale erosion experienced on the hillslope in sheet and rill erosion has remained a challenge to detect. This research addresses two of the challenges in using terrestrial LiDAR on fine scales in two …
Michigan's Clay Bluffs: The Description And Comparison Of An Erosion-Dependent Natural Community, Nathaniel G. Fuller
Michigan's Clay Bluffs: The Description And Comparison Of An Erosion-Dependent Natural Community, Nathaniel G. Fuller
Masters Theses
The clay bluffs of Michigan are a natural community found along the shores of the Great Lakes. Groundwater is found to be critical to sustaining the alkaline wetlands on the face of the bluff as well as the source of most erosion events. The clay bluffs are unusual in their vegetation, disturbance regime and geographical context. This thesis focuses primarily on describing seeping clay bluffs and exploring the comparison to other natural communities. The purpose of this is twofold, to better understand the ways in which natural communities are described as distinct from one another, and to assess the distinctness …
A Spatial Analysis Of Streambank Heterogeneity And Its Contribution To Bank Stability, Paul Vanterpool Simmons
A Spatial Analysis Of Streambank Heterogeneity And Its Contribution To Bank Stability, Paul Vanterpool Simmons
Masters Theses
Streambank erosion is a function of fluvial detachment and geotechnical failure mechanisms working in combination to cause bank retreat. It is generally agreed that bank stability is dependent on both types of erosion; however, few studies have attempted to correlate the driving and resisting forces between the two. It has been proposed that: (1) streambanks possess a spatial structure and dependence of non-erodible resistant structures such as root masses and rocks; (2) streambanks naturally “armor” themselves from fluvial erosion with a combination of hard points and resistive soil; and (3) the stability of the streambank can be predicted by the …
Composted Biosolids As A Soil Cover On Steep Slopes, Justin Lee Fisher
Composted Biosolids As A Soil Cover On Steep Slopes, Justin Lee Fisher
Masters Theses
Municipal sewage disposal and soil erosion control from highly disturbed sites are both large scale issues of environmental concern. Composted biosolids (CBS) and shredded wood have the potential to be applied as soil cover to address both disposal and erosion issues. There is a lack of information on the use of these products on steep slopes, typical of construction sites. The objective of this study was to evaluate the use of CBS for reducing erosion and establishing vegetation on a cherty, slightly compacted, Fullerton Series sub-soil embankment, with an average slope of 46.5 percent. The study was conducted at the …
