  • A study on the oxidation of sulfides in estuarine waters

    Creator:
    Korpalski, Thomas Paul
    Abstract:
    Waters of various salinities were secured from the Umpqua estuary, the Umpqua River, and the open ocean near the mouth of the estuary. The rate of oxidation of sulfides in these various waters was investigated to assess the potential longevity of free sulfides in estuarine waters. The rate of disappearance...

  • Cable dynamics in an ocean environment

    Creator:
    Tuah, Hang
    Abstract:
    The nonlinear dynamic analysis of cable and cable-large body systems subject to both deterministic and non-deterministic loading is presented in this study. Nonlinearities occur due to large displacements, material nonlinearity, lack of stiffness in compression, and the non-conservative fluid loading. A finite element model is used to model the cable...

  • Probabilistic Tsunami Hazard and Damage Assessment of the Built Environment : Applied at Seaside, Oregon

    Creator:
    Park, Hyoungsu
    Abstract:
    Damage estimates to the built environment from tsunamis are important for disaster mitigation, including planning emergency response and recovery. This dissertation evaluates the damage states of buildings in a small urban coastal city, Seaside, Oregon, from tsunami hazards generated by a Cascadia Subduction Zone (CSZ) event. This study is separated...

  • Evaluation of Topography and Seismicity on Shallow Landslide Susceptibility

    Creator:
    Hess, Daniel M.
    Abstract:
    Shallow landslides are a prevalent concern in mountainous regions that can result in severe societal, economic, and environmental impacts. The challenge is further compounded as the size and location of a potential slide is often unknown. This study presents a generalized approach for the evaluation of shallow landslide susceptibility using...

  • Munition Mobility in Mixed Grain (Sand and Cobble) Environments

    Creator:
    Paskoski, Jessica
    Abstract:
    Nearly 24% of Formerly Used Defense Sites (FUDS) containing military munitions are in the nearshore coastal zone with approximately 30% of those sites containing heterogeneous sediment compositions of gravel-sand. Previous exploration in munition mobility was performed on beaches of sandy or muddy bottoms leaving the influence of heterogeneous sediment properties...

  • The static and dynamic analysis of discretely represented moorings and cables by numerical means

    Creator:
    Dominguez, Richard Frank
    Abstract:
    Computer oriented techniques and procedures are presented for the analysis of single and multiple cable systems. Application is made to a two-point mooring system influenced by surface and subsurface hydrodynamic loading. The effects of the various parameters are presented and the numerical method is compared to exact solutions obtained from...

  • Remote Sensing Tools for Evaluating Climate Change Impacts in Coastal Environments

    Creator:
    Herrmann, Joan F.
    Abstract:
    Climate change has pervasive impacts on Earth’s diverse ecosystems. Observed and projected effects that impact coastal environments pose unique challenges. Coastal regions provide numerous ecosystem services (e.g., fisheries, nursery habitats, erosion control, and water filtering and detoxification), house 40% of the US population, and contribute to 58% of the national...

  • Quantifying the Relative Role of the Key Drivers of Coastal Dune Evolution: Observations and Simulations Across a Range of Time and Space Scales in Cape Lookout National Seashore, North Carolina

    Creator:
    Hovenga, Paige A.
    Abstract:
    Coastal dunes provide a diverse set of ecosystem services including coastal protection against destructive surge and waves during storm events. Dunes are constantly evolving through various stages of response to storm events and post-storm recovery at rates that vary due to a range of drivers including pre-existing morphology, environmental forcing...

  • Conceptual Representations within the Social and Material Contexts of an Engineering Workplace and Academic Environments

    Creator:
    Barner, Matthew S.
    Abstract:
    Situated cognition theory emphasizes the role that social and material contexts have on learning and knowledge application. Several studies of engineering workplace environments have noted differences between the social and material contexts of the workplace and those of undergraduate engineering education. No existing research has studied the social and material...

  • Networked Multi-agent Modeling of Connected Vehicles in Mixed Traffic Environment: A Decentralized Consensus Approach

    Creator:
    Wahid, Merih
    Abstract:
    Transportation systems are facing safety and operational challenges with a cost of billions of dollars annually in lost production time and wasted fuel. Infrastructure expansion, previously held as a panacea to most transportation challenges has lost its appeal due to financial, land-use and environmental constraints. Interest is surging in intelligent...
