  • 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...

  • Large scale model testing of the FMC submerged wave attenuation device

    Creator:
    Huber, David S.
    Abstract:
    This report describes the hydrodynamic testing and evaluation of a one-tenth scale model of the FMC Wave Attenuation Device. The purpose of the test was to quantify the wave attenuation characteristics and structural loading induced by a test program of monochromatic incident waves on the submerged structure. The device was...

  • Use of benthic sediments as indicators of marina flushing

    Creator:
    Noble, Scott Morgan
    Abstract:
    This report presents the findings of a sediment analysis program formulated to determine the flushing potential of various shaped small boat marina basins. Chemical tests regarding volatile solids, Kjeldahl nitrogen, grease and oil, and sulfides were performed with the results compared to established sediment quality criteria. These results were used...

  • 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...

  • 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...

  • Pollution and tidal flushing predictions for Oregon's estuaries

    Creator:
    Choi, Byungho
    Abstract:
    The overriding goal of this study was to provide first order estimates of dilution and tidal flushing of waste discharges released hypothetically into various Oregon estuaries during critical low flows and tides. Causal relationships between discharged wastes and subsequent estuarine response were studied. Various approaches to determine the assimilative capacity...

  • 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...
