Challenges In Approaching The Detection Limits For Hillslope Erosion Using Terrestrial Laser Scanning, Gene Nathan Bailey Iii May 2022

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 …


A Spatial Analysis Of Streambank Heterogeneity And Its Contribution To Bank Stability, Paul Vanterpool Simmons May 2014

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 May 2012

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 …
