  • 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...

  • 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...

  • 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...

  • 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...

  • Finite amplitude deep water waves : a comparison of theoretical and experimental kinematics and dynamics

    Creator:
    Jensen, Robert E.
    Abstract:
    Problems associated with quantification of deep water wave kinematics and dynamics are examined. Summaries of Stokes' theory and Dean's stream function theory are reported. A computer algorithm is developed to solve the hydrodynamic characteristics for Stokes' fifth and third order and linear theories. Tests are initiated to verify the results...

  • 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...

  • Chetco River tidal hydrodynamics and associated marina flushing

    Creator:
    Tang, Shing Shirly
    Abstract:
    The purpose of this study was to provide an understanding of the interrelationships between fresh and salt water Circulation, tidal transport and flushing patterns in the Chetco River estuary and its boat basins. Field work and water quality measurements were conducted at the entrance of the Chetco River during 1975...

  • 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...
