  • 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...

  • Sand waves in a pristine estuary

    Creator:
    Baliga, B. R. (B. Ravindranath)
    Abstract:
    The stochastic and the Fourier theories for sand waves developed by Lee(11) and Hino(6), respectively, for unidirectional flows are extended in order to estimate the rate of sediment turnover (RST) under oscillatory flows in the South Slough estuary, Coos Bay, Oregon. Data were collected by a mechanical and a sonic...

  • 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...

  • 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...

  • Offshore controls on nearshore circulation

    Creator:
    Long, Joseph W.
    Abstract:
    The rip current field resulting from the transformation of surface gravity waves over offshore submarine canyons is studied. Employing a wave transformation model and a wave-induced circulation model over observed bathymetry we find that rip current circulation cells exist with alongshore spacing of O(1OOm) even though the nearshore bathymetry displayed...

  • A laboratory experiment on sand bar migration with comparisons to recent models

    Creator:
    Magalen, Jason
    Abstract:
    Successful prediction of nearshore sediment migration is important in determining the vulnerability of a coastline. During energetic wave climates (storm events) sediment rapidly erodes from beaches and is deposited offshore. In subsequent milder wave conditions, the sediment migrates shoreward, accreting on the beach and helping to protect the coastline. It...

  • 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...
