  • Nearshore wave predictions along the Oregon and southwest Washington coast

    Creator:
    García-Medina, Gabriel
    Abstract:
    This thesis contains a manuscript describing the implementation of a high resolution wave forecasting model for the coasts of Washington and Oregon. The purpose of this project was to advance the wave predictive capabilities of the states of Oregon and the southwest part of Washington by including the effects of...

  • Effects of Wave Nonlinearity and Vertical Variation of Vegetation Density on Wave Attenuation

    Creator:
    Wu, Wei-Cheng
    Abstract:
    The understanding and prediction how coastal wetland vegetation attenuates wave action has received renewed attention with global climate change impacts and increasing populations on coastlines. Conventional attenuation models utilize empirical drag coefficients, but these coefficients exhibit a wide range of values, and there is some uncertainty in the relative importance...

  • On the nearshore impact of wave energy converter arrays

    Creator:
    O'Dea, Annika Magnuson
    Abstract:
    Radiation stresses, defined as the excess flow of momentum due to the presence of waves (Longuet-Higgins, 1964), are the main drivers behind the cross-shore and longshore forcing that results in wave setup, set-down, and longshore currents (e.g. Svendsen, 2006). Longshore currents entrain and transport sediment and therefore play an important...

  • Coupled wave and surge modeling of Tillamook Bay, Oregon : extreme events and climate change impacts

    Creator:
    Cheng, Tiffany Kay
    Abstract:
    Estuaries represent the confluence of land and ocean environments and encompass a number of complex interactions amongst tides, winds, offshore waves and the riverine contributions, all of which contribute to total water levels (TWLs). The study of TWLs and the relative weight of its components can assist local communities in...

  • Experimental and numerical modeling of wave height attenuation by emergent coastal vegetation

    Creator:
    Blackmar, Philip James
    Abstract:
    Coastal vegetation dampens waves which can provide benefits to the local area, but existing literature shows large variations in the degree of wave height attenuation depending on plant properties and wave conditions. Better knowledge of how to predict the wave height decay accurately in different types of vegetation may help...

  • 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...

  • Wave modeling at the mouth of the Columbia River

    Creator:
    Kassem, Sarah
    Abstract:
    As the second largest river in the U.S., the entrance to the Columbia River is home to some of the most extreme wave conditions on the Pacific Coast. Winter storms commonly generate waves 6-8 m in height, which in combination with strong tidal currents, can produce dangerous navigation conditions. To...

  • 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...

  • Observations and prediction of intermittent sediment suspension in the surf zone

    Creator:
    Yoon, Hyun Doug
    Abstract:
    In this dissertation the interactions between hydrodynamics, sediment suspension and transport, and morphological evolution in the surf zone was investigated with a large-scale laboratory experiment data, CROss-Shore Sediment Transport Experiment (CROSSTEX). The data set included comprehensive measurements of water surface elevation, fluid velocity, sediment concentration, and morphology for irregular waves...

  • Parametric uncertainties in reliability analysis of bridge structures

    Creator:
    Hamutcuoglu, Osman Murat
    Abstract:
    Probability-based reliability methods have placed an increased emphasis on realistic simulation of structural behavior in bridge engineering. Uncertainty is present in every aspect of structural analysis. Aleatory uncertainties in the loading and load-carrying capacities, and epistemic uncertainties in mathematical idealization of bridge systems are the major contributors to uncertain structural...
