  • Transport and adsorption of proteinanceous particles during flow through porous media

    Creator:
    Yamamoto, Tokuo
    Abstract:
    This is a fundamental study of the mechanism of protein particle removal during flow through sandy soil. Mathematical models for diffusion-adsorption and diffusion-convection-adsorption processes were developed and compared with experimental data. An attempt was made to calculate the distance over which the adsorption forces act. The differential equation for the...

  • A study on the oxidation of sulfides in estuarine waters

    Creator:
    Korpalski, Thomas Paul
    Abstract:
    Waters of various salinities were secured from the Umpqua estuary, the Umpqua River, and the open ocean near the mouth of the estuary. The rate of oxidation of sulfides in these various waters was investigated to assess the potential longevity of free sulfides in estuarine waters. The rate of disappearance...

  • The static and dynamic analysis of discretely represented moorings and cables by numerical means

    Creator:
    Dominguez, Richard Frank
    Abstract:
    Computer oriented techniques and procedures are presented for the analysis of single and multiple cable systems. Application is made to a two-point mooring system influenced by surface and subsurface hydrodynamic loading. The effects of the various parameters are presented and the numerical method is compared to exact solutions obtained from...

  • Air photo analysis of waste dispersion from ocean outfalls

    Creator:
    James, Wesley Pierce
    Abstract:
    Aerial photography provides a method of analyzing dispersion of wastes that are discharged into the ocean. This method is more comprehensive than conventional boat sampling in dispersion studies. The photographic technique permits waste concentrations to be measured throughout the plume in one instant; thereby allowing the diffusion analysis to be...

  • Curriculum synthesis and amelioration : a case study of undergraduate civil engineering

    Creator:
    Hamernik, Robert E.
    Abstract:
    The dynamic philosophy of education as applied to the undergraduate Civil Engineering program has been influenced by such factors as the introduction of new theories, the demands and needs of our society and the personnel responsible for teaching. These changes are reflected in the curriculum as witnessed by a historical...

  • Pollutants leached from selected species of wood in log storage waters

    Creator:
    Graham, John LeRoy
    Abstract:
    A study was conducted to determine the quantity and character of substances leached from logs floating in water, and the rate of leaching of these substances. The species of wood studied were Douglas fir and ponderosa pine. The research was carried out in a controlled laboratory environment with log sections...

  • The use of polymers for better settling in domestic waste treatment systems

    Creator:
    Houck, George Campbell
    Abstract:
    The author presents a "state of the art" of the use of polymers for better settling in domestic waste treatment and evaluates the published research in the field. Polymers have only recently been used to obtain better settling in domestic waste treatment. Due to the number of polymer types available...

  • Evaluation of estuarine channel conditions in Coos Bay, Oregon using side-scan sonar

    Creator:
    Hartman, Gregory L.
    Abstract:
    Side-scan sonar records in Oregon's Coos Bay estuary navigation channels were obtained at intervals of two to three months during the November 1974 - October 1975 time period from Coos Bay Channel Mile 11+50 to 15+20, and from a reach in the Marshfield Channel. A limited side-scan survey effort was...
