  • Design and implementation of a physical model for Keystone Harbor, WA

    Creator:
    Richmond, J. Brady
    Abstract:
    Strong tidal currents experienced at Keystone Harbor, WA, have caused navigational hazards and disrupted ferry service in the area. This thesis presents details of the design, construction and implementation of a large scale physical model of Keystone Harbor used to evaluate the effectiveness of proposed jetty design alternatives to improve...

  • Nowcast/forecast of storm surge and drawdown using a hybrid FE/ANN approach

    Creator:
    Darnell, Joel T.
    Abstract:
    In the northwestern Gulf of Mexico there is a need for reliable water level forecasts to facilitate safe commercial navigation, marine construction, and emergency management. Though the low amplitude tides of the region can be predicted with conventional harmonic techniques, frequent strong storms make accurate forecasts of water levels difficult....

  • Dynamic response of an offshore structure to measured and simulated stochastic wave forces

    Creator:
    Grecco, Michael G.
    Abstract:
    The dynamic response of an offshore structure to measured and simulated stochastic wave forces is investigated. The theoretical nondeterministic analysis is performed in the frequency domain for a two-dimensional model. The ocean wave system is assumed to be a zero mean, stationary, ergodic Gaussian process described by a one-dimensional wave...

  • 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...

  • Large-scale laboratory observations of wave breaking turbulence on a fixed barred beach

    Creator:
    Scott, Christopher P.
    Abstract:
    This thesis presents the details of a large-scale laboratory experiment to study the turbulence generated by waves breaking on a fixed barred beach. The data set includes comprehensive measurements of free surface displacement and fluid velocity for one random and one regular wave case. Observations of the time-averaged turbulent kinetic...

  • Laboratory observations of tsunami runup on a complex 3D bathymetry using PIV

    Creator:
    Ichikawa, Shingo
    Abstract:
    This thesis presents the details of a large-scale laboratory experiment to study the runup velocity on a complex 3D bathymetry. The PIV measurements including the instrumental setup, the recording procedure, and the image processing are presented. Tsunami inundation directly affects the coastal population and is one of the most important...

  • An analysis of wave forces on prototype walls under tsunami loading

    Creator:
    Oshnack, Mary Elizabeth
    Abstract:
    This thesis is comprised of two manuscripts based on a laboratory experiment conducted to examine realistic wave forcing on a vertical wall subjected to tsunami loading. The first manuscript examined tsunami force and pressure distributions on a rigid wall that was fronted by a small seawall. Six different seawall heights...

  • 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...

  • Wave propagation processes at the mouth of the Columbia River

    Creator:
    Andes, Lisa (Lisa Christine)
    Abstract:
    The mouth of the Columbia River (MCR) has a longstanding reputation of hazardous navigational conditions. This reputation has been developing since the first ship, the Columbia, traversed through the inlet in 1792. The hazardous conditions are related to the large waves and strong tidal currents that are common in the...

  • Analysis of pressure variations observed at the ocean bottom during the 2003 Tokachi-Oki earthquake

    Creator:
    Li, Wenwen
    Abstract:
    Most tsunami studies have been conducted based on the incompressible fluid theory. However water compressibility must be considered for the process of tsunami generation by bottom displacements during submarine earthquakes. During the 2003 Tokachi-Oki earthquake, the ocean-bottom pressure variations were registered by the pressure gauges PG1 and PG2 located right...
