  • Evaluation of the performance of a taut-moored dual-body direct-drive waveenergy converter through numerical modeling and physical testing

    Creator:
    Elwood, David E.
    Abstract:
    With energy prices rising and increasing concern about the influence of fossil fuels on climate change, wave energy systems are on the verge of commercial implementation. These first generation wave energy converters utilize either pneumatics or hydraulics to convert the mechanical energy of waves into electricity. For the last several...

  • An experimental study and a three-dimensional numerical wave basin model of solitary wave impact on a vertical cylinder

    Creator:
    Zhang, Wenbin
    Abstract:
    An experiment on solitary wave impact on a vertical cylinder was conducted in the three-dimensional wave basin at the Oregon State University Hinsdale Wave Research Laboratory. The cylinder was designed using mechanic principles and finite element analysis techniques to enable accurate measurement of horizontal force and overturning moment. Video data...

  • Airphoto analysis of estuarine circulation

    Creator:
    Weise, Harry Gordon
    Abstract:
    Aerial photography has become a valuable method of acquiring information on estuarine current circulation patterns. The method provides a comprehensive picture of nearly simultaneous surface water movements. It represents a significant improvement over conventional surface float and current meter methods because large areas may be covered in great detail with...

  • Influence of macro-roughness on tsunami runup & forces

    Creator:
    Bridges, Kerri-Jane
    Abstract:
    This thesis is comprised of a manuscript based on a laboratory experiment run in the Tsunami Wave Basin as part of a research project funded by the Network for Earthquake Engineering Simulation called Housesmash. The purpose of the experiment was to better understand the role of the urban environment, represented...

  • Nearshore hydrodynamic model comparisons and predictions of bathymetric evolution

    Creator:
    Lescinski, Jamie M.
    Abstract:
    The surf zone exhibits large energetic signals from wave shoaling and subsequent dissipation due to breaking, forcing circulation. The bathymetry responds to the wave and wave-induced circulation with the growth, transport, and destruction of large scale bathymetric features, such as mega ripples and sand bars. There is an obvious fluctuation...

  • Wave field patterns generated by wave energy converters

    Creator:
    McNatt, J. Cameron
    Abstract:
    The eventual deployment of wave energy converters (WECs) on a commercial scale will necessitate the grouping of devices into arrays or "wave farms," in order to minimize overhead costs of mooring, maintenance, installation, and electrical cabling for shoreward power delivery. Closely spaced WECs will interact hydrodynamically through diffracted and radiated...

  • Analysis of rip current embayments on the Oregon coast

    Creator:
    Dalon, Matthew M.
    Abstract:
    Understanding the past, present, and future behavior of our nation's shorelines is vital for sensible coastal management. Localized areas of erosion, termed "erosional hot spots", can shift the shoreline landward threatening coastal infrastructure (Kraus and Galgano, 2001; Stauble and Gravens, 2004; McNinch, 2004). One specific type of erosional hot spot...

  • A large scale model study of placed stone breakwaters

    Creator:
    DeBok, Donald H.
    Abstract:
    The results of three hydraulic model tests to evaluate the stability of a placed stone breakwater are presented and discussed. The prototype breakwater was designed to protect offshore power and port facilities in 60 feet of water and was tested at scale ratios of 1:10, 1:20, and 1:100. The armor...
