Spatial and temporal trends in bed material and channel morphology below a hydroelectric dam complex, Deschutes River, Oregon

Creator:: McClure, Ellen M.
Abstract:: River regulation imposes changes in the supply of sediment and the frequency of competent flows. As a result, impounded rivers often exhibit downstream changes in channel processes, particle size, and morphology. The magnitude of change in competent flow frequency and sediment load together can be used to predict the pattern...

Dynamic response of steel structures with semirigid connections

Creator:: Grant, Joseph Edward
Abstract:: The nonlinear response of a ten-story steel structure with semirigid girder connections is studied under conditions of dynamic loading. The dynamic loading used in this study is the North-South component of the May 18, 1940 El Centro, California earthquake. To deal with the complexity of the problem the structure is...

Matrix analysis of structures with semi-rigid connection

Creator:: Grant, Joseph Edward
Abstract:: This thesis presents a matrix analysis of structures with semirigid connections. The stiffness factor of a connection has been assumed to be a constant as represented by the initial relationship of moment versus rotation. Three cases are considered: Case I - structures with semirigid connections, column width and beam depth...

Comparison and Validation of Hydrodynamic Theories for Wave Energy Converter Modelling

Creator:: Leary, Matthew M.
Abstract:: A wide variety of hydrodynamic theories are utilized to approximate a Wave Energy Converter’s (WEC) equation of motion. Numerous theories have been refined in order to improve numerical approximations of WEC dynamics. When incorporating refined hydrodynamic theories into numerical models, there are distinct impacts on WEC rigid body motions, cable...

Testing and Modeling of a Cross-Laminated Timber Pier-and-Spandrel Seismic Retrofit Solution for Unreinforced Masonry Buildings

Creator:: Engleson, Renee M.
Abstract:: Cross-laminated timber (CLT) is an attractive building material because it is renewable, promotes fast installation, and possesses a high strength-to-weight ratio. The use of CLT in seismic applications has become increasingly common with the development of post-tensioned CLT rocking wall lateral force resisting systems (LFRS). The CLT pier-and-spandrel system designed,...

Remote and Ground-based Methods for Monitoring Vegetation Health Parameters in a Bioretention Facility

Creator:: Prettyman, Kery M.
Abstract:: The growing contamination of surface water by stormwater runoff parallels increasing urban development. Heavy metals, polycyclic aromatic hydrocarbons (PAHs), persistent organic pollutants (POPs), and contaminants of emerging concern (CECs) are discharged from point sources and washed from impervious surfaces into surface waters, impacting the ecology of these systems, food supplies,...

Improving Region-Scale Landslide Inventory and Susceptibility Mapping

Creator:: Bunn, Michael D.
Abstract:: Landslides are a natural hazard that have major societal, economic, and environmental impacts. The understanding of landslides begins with the observation that they are a spatial problem. Spatial relationships have historically been explored with maps, and landslides are no different. Such maps range in focus from inventory maps, which identify...

An Exploration of Faculty Sensemaking in the Adoption of Course Social and Cognitive Engagement (CSCE) Surveys

Creator:: Ironside, Allyson J.
Abstract:: The work of engineering education researchers has resulted in the development of research-based instructional strategies (RBISs) aimed at providing educators with means to increase student learning. Research has shown that there is a disconnect between the development of RBISs and their use by educators. Means to make new practices more...

Investigation of Drilled Shafts under Axial, Lateral, and Torsional Loading

Creator:: Li, Qiang
Abstract:: Drilled shaft foundations provide significant geotechnical resistance for support of structures, such as highway bridges, traffic sign, and signal pole structures, and are used widely to meet their structural foundation requirements. The amount of steel reinforcement in drilled shaft foundations has increased over the past several decades to account for...

Biodegradation of methyl tert-butyl ether (MTBE) and its breakdown products by propane and iso-pentane grown Mycobacterium vaccae and Graphium sp. : cometabolism, inhibition, kinetics, and modeling

Creator:: Martínez-Prado, Maria Adriana
Abstract:: Mycobacterium vaccae JOB5 and Graphium sp. were studied to evaluate their ability to cometabolize methyl tert-butyl ether (MTBE) and its metabolites after growth on two different alkanes, propane and iso-pentane. Both cultures were capable of cometabolizing MTBE and the metabolites, tert-butyl formate (TBF) and tert-butyl alcohol (TBA). MTBE, TBF, and...
