Acoustic Behavior Of Soil Reinforced With Grass Roots, Blake Armstrong
Acoustic Behavior Of Soil Reinforced With Grass Roots, Blake Armstrong
Electronic Theses and Dissertations
Civil engineering practice has shown that vegetative roots on slopes and streambanks can substantially increase shear strength of soil and reduce erosion. Research has been done to understand and quantify the effect. Most studies have been conducted on slopes and streambanks with woody vegetation. Past research has used a perpendicular root model to predict increase in cohesion, or shear strength, due to the mobilization of roots' tensile strength. Acoustics can be used to monitor internal changes of soil by interacting with soil particles and interstitial fluids. Compressional wave, or p-wave, velocity can be used to predict changes in effective stress …
Reconstructing Lithofacies Of The Norphlet Formation (Jurassic) As Potential Exploration Targets: Little Cedar Creek And Brooklyn Fields, Southwest Alabama, Catherine E. Henry
Reconstructing Lithofacies Of The Norphlet Formation (Jurassic) As Potential Exploration Targets: Little Cedar Creek And Brooklyn Fields, Southwest Alabama, Catherine E. Henry
Electronic Theses and Dissertations
The Norphlet Formation is a Jurassic-aged siliciclastic unit located across the southeastern United States and offshore Gulf of Mexico. The eolian dune sands present in the Norphlet Formation serve as oil and gas reservoirs, making the formation of particular interest to oil and gas companies. Stable Appalachian ridges are the source of the Norphlet Formation, however deposition is related to complex faults and structures resulting from movement of the Louann Salt. Erosion of the ancestral Appalachian Mountains resulted in the deposition of four main lithofacies: basal shales, conglomerates and conglomeratic sandstones, the Denkman Sandstone member, and a redbed succession. Additionally, …
