Groundwater Flooding and Guerrilla Trenches : a Participatory Approach for Flood Control

Creator:: Kemper, Joseph B.
Abstract:: Residents in South Falls City, a small town in the foothills of Oregon's Coast Range, battle intense flooding during the rainy season. Disagreements about surface water management pit neighbor against neighbor, but preliminary evidence suggests that groundwater flooding is an underlying cause. OSU researchers pair the emerging literature on groundwater...

5th-Order Elliptic LPF Using Passive Charge Compensation Technique (PCC) Design

Creator:: Tsai, Cheng H.
Abstract:: The passive charge compensation (PCC) technique was introduced for switched capacitor (SC) circuit to increase the slew rate and enhance the linearity performance, as PCC techniques are used on the Delta-Sigma modulator (DSM) in ADC circuitry. The PCC technique of the project was applied to the design of a SC...

Carbon Dynamics Associated with Land Cover Change in Tropical Mangrove Ecosystems of the Mahakam Delta, East Kalimantan, Indonesia

Creator:: Arifanti, Virni B.
Abstract:: The Mahakam Delta which was once among the largest mangrove forests in Indonesia, has been subjected to dramatic changes in structure and function due to massive shifts from mangrove forest to shrimp ponds and oil and gas development. To understand the impacts of mangrove loss to the greenhouse gas (GHG)...

Characterization of the Small-Strain Stiffness of Soils at an In-situ Liquefaction Test Site

Creator:: Donaldson, Aleyna M.
Abstract:: Strong ground motions from earthquakes can result in the reduction of the shear modulus and wave propagation characteristics of soils, and can produce liquefaction and cyclic softening during shaking and for some time following the seismic event. While the ground motions produced from controlled blasting are different than those in...

Microbial Community Composition as a Driver of Chemical Composition Change in Streams and Wastewater

Creator:: Mahadwar, Gouri
Abstract:: Microbial communities in aquatic systems are dominant drivers of chemical transformation, including contaminants of emerging concern (CECs). This study quantified shifts in microbial communities and their relationship to shifts in chemical composition in surface waters in the Willamette Valley, Oregon. In addition to bulk chemical composition shifts, the relationship between...

Feasibility of Thermal Restoration by Groundwater Additions in the Middle Fork John Day

Creator:: Hale, Abigail E.
Abstract:: Survival of ecological systems pivot on critical moments. In the arid John Day Basin of Eastern Oregon, extensive restoration of the stream and floodplain focused on supporting salmon has been ongoing for the past 20 years, but recurring short periods of extreme temperature increase and low flows result in mortality...

Plate boundary deformation of the Pacific plate : two case studies

Creator:: Leitner, Beate
Abstract:: Two examples of Pacific rim plate boundary deformation are presented. In the first part of the thesis crustal models are derived for the northwestern part of the Vizcaino block in California using marine seismic and gravity data collected by the Mendocino Triple Junction Seismic Experiment. A northwest-southeast trending kink in...

Bridge Model Parameter Sensitivity in Pushover and Nonlinear Time History Analysis

Creator:: Johnsohn, Karryn E.
Abstract:: The aim of this research is to understand and quantify the modeling differences between CSiBridge and OpenSees, and to determine sensitive model parameters. When designing bridges for the high seismic region of California, the California Department of Transportation (Caltrans) performs nonlinear time history analysis of their bridge models. For three-dimensional...

Heat Flow from a Vapor-Dominated Sublacustrine Vent Field Beneath Yellowstone Lake

Creator:: Favorito, Julia E.
Abstract:: Portions of Yellowstone Lake sit on top of a vigorous but not well understood hydrothermal system situated in a region of intense geologic and environmental forcings. A heat flow study conducted over the Stevenson Island Vent Field (SIVF), a vent field at the bottom of Yellowstone Lake underlain by an...
