  • 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...

  • 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...

  • Large displacement, high Reynolds number oscillating cylinder

    Creator:
    Chan, Yau Wai
    Abstract:
    Hydrodynamic forces on a cylinder oscillating horizontally underwater with its axis perpendicular to the motion were measured at the Oregon State University Wave Research Facility. The cylinder had an outer diameter of 12 inches and a length of 12 feet. For the data presented herein, the maximum displacement of the...

  • Hydrodynamic forces on a horizontal cylinder under waves and current

    Creator:
    Teng, Chung-chu
    Abstract:
    By assuming the linear superposition principle to be valid, the hydrodynamic forces on a horizontal cylinder under waves and current are examined. In this study, towing a cylinder in waves is used to simulate a cylinder under waves and current. The experimental technique is proved valid through theoretical considerations and...

  • Forces on a transverse circular cylinder in a steady uniform flow near a plane boundary

    Creator:
    Hafen, Blaine
    Abstract:
    An experimental study was conducted to determine the hydrodynamic forces on smooth and roughened circular cylinders as influenced by a nearby plane boundary. The ambient flow was perpendicular to the cylinder and parallel to the boundary. Measurements were taken in a water channel and a wind tunnel to obtain the...

  • An underwater acoustic imaging system

    Creator:
    Kolar, Michael John
    Abstract:
    An experimental underwater acoustic imaging system has been designed and built. Operating at 650 KHz, real time acoustic images are obtainable. Using both geometrical optics and Fourier optics, the theory of image formation and resolution is presented. Other factors affecting image quality and system acuity are also discussed. System components...

  • 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...

  • The analysis of directional wave spectra from current and pressure measurements

    Creator:
    Lin, Li-hwa
    Abstract:
    Directional wave spectra have been estimated in this study based upon simultaneous subsurface measurements of current and pressure. Two previously developed methods, the stochastic and deterministic approaches, have been reviewed and restudied. It is demonstrated by means of the Correlation Theorem that the stochastic and deterministic approaches are, under certain...
