  • An investigation on the modeling of wave field transformation and shoreline morphology near steep bathymetric features

    Creator:
    Michalsen, David R.
    Abstract:
    Steep bathymetric anomalies in the beach profile, such as offshore borrow pits, submerged breakwaters, and nearshore canyons can significantly transform the wave climate through the effects of refraction, diffraction, and reflection. When located in the nearshore region the modified wave climate can also substantially change the location of breaking and...

  • Hydrodynamic loads on fiber-optic micro cables

    Creator:
    Evans, Matthew R.
    Abstract:
    A Finite Element Model of a deployed Fiber-Optic Micro Cable (FOMC) was performed using the marine cable modeling software, OrcaFlex. The focus of this study was a parametric analysis of a two-part, towed cable array with the FOMC dragged behind a depressor and connected to a drogue chute. Length-to-diameter ratios...

  • A Framework for Analyzing Debris Removal Operations Using Discrete Event Simulation

    Creator:
    Vijay, Akash
    Abstract:
    Debris generated after a disaster event must be disposed efficiently for community recovery. This is a significant operation that accounts for up to 27% of the total recovery costs. Generally, debris removal takes place in two phases: the short-term relief phase, which involves debris removal immediately after a disaster to...

  • Power Output Calculations for an Array of Point-absorber Wave Energy Converters

    Creator:
    García-Castaño, Manuel
    Abstract:
    This study presents a methodology for power take off (PTO) forecasting for an array of heave wave energy converters (WECs). Based on spectral data obtained directly from the National Data Buoy Center, representative realistic sea states are generated at the location of the WECs, and by using two wave-structure interaction...

  • Multi-hazard framework and analysis of soil-bridge systems : long duration earthquake and tsunami loading

    Creator:
    Carey, Trevor J.
    Abstract:
    During the 2011 Great East Japan Earthquake and Tsunami, numerous bridge structures were damage or destroyed. The damage to bridge systems was caused by long duration strong ground shaking, tsunami inundation forces, or both. Long duration strong ground shaking from subduction zone earthquakes and the multi-hazard scenario of combined earthquake...

  • Mooring analysis of the Ocean Sentinel through field observation and numerical simulation

    Creator:
    Baker, Joshua L.
    Abstract:
    This study presents a mooring analysis of the Ocean Sentinel buoy, which is a mobile test platform for Wave Energy Converters. The Ocean Sentinel is owned and operated by the Northwest National Marine Renewable Energy Center (NNMREC) at Oregon State University (OSU). The study involved a field observation as well...

  • Tsunami propagation in large rivers : idealized cases and the Columbia River Estuary

    Creator:
    Kalmbacher, Kirk D.
    Abstract:
    The hazards associated with tsunamis are well known and have been studied for decades. The majority of research is, however, focused on open coastlines which bear the brunt of a tsunamis force. Other regions that can be strongly impacted by a tsunami are large estuaries. Here, the tsunami encounters a...

  • Tidal range changes in the Delaware Bay : past conditions and future scenarios

    Creator:
    Hall, George F.
    Abstract:
    Throughout the Holocene, appreciable changes in bathymetry are hypothesized to have resulted in large changes to tidal datums in coastal and estuarine areas. An understanding of tidal change is an important contribution to the knowledge of relative historical sea-level change and future coastal planning. To test this hypothesis, the Advanced...

  • Determinants of public opinion on renewable energy : the case of wave energy development in Oregon

    Creator:
    Stefanovich Petrova, Maria A.
    Abstract:
    Renewable energy resources, such as wind, solar, and wave, have a number of advantages compared to traditional fossil fuels. Numerous studies attest to the physical potential for wave energy development in Oregon. In transitioning from conventional fossil fuel to alternative energy provision, citizen understanding of the global energy problems and...

  • Laboratory performance of highway bridge girder anchorages under hurricane induced wave loading

    Creator:
    Lehrman, Jora
    Abstract:
    Many bridges along the Gulf Coast of the United States were damaged by recent hurricanes, and many more are susceptible to similar damage. This research examines performance of common anchorage connection details for AASHTO Type III prestressed concrete girders used by some transportation agencies. Full-scale specimens were fabricated and tested...
