  • A system analysis method for water quality management by flow augmentation

    Creator:
    Worley, John Larry
    Abstract:
    A rapid expansion of population and industrialization in recent years has created new and difficult problems in water resources management. Prudent management of water quality will require that more efficient methods be developed for evaluating large volumes of data on complex river systems, and tabulating the results in a form...

  • Numerical and physical modeling of wave forces on A-Jacks units

    Creator:
    Wise, Larry
    Abstract:
    A numerical model is developed to estimate wave forces on A-Jacks armor units. The forces include drag, inertia, buoyancy, and slamming as the unit penetrates the free surface. The wave force model is used to determine the rigid body motions of the units. Bulk forces on a matrix of units...

  • The wastewater treatment characteristics of a rotating flighted cylinder

    Creator:
    Hansen, Larry Bruce
    Abstract:
    The rotating flighted cylinder (RFC) was investigated as a potential wastewater treatment deVice. A RFC is a rigid tube with a helically-wound fin attached to the interior surface and operates by flowing wastewater through the tube as it rotates. An 8-inch and 24-inch diameter RFC was tested for solids-liquid separation,...

  • 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...

  • The effect of the diameter and spacing of manifold outlets on manifold flow

    Creator:
    Coleman, Michael Dale
    Abstract:
    A laboratory investigation was undertaken to evaluate the effect of lateral spacing and lateral diameter on the flow characteristics of a three dimensional blowing manifold. The model used in the experimental work was constructed of clear cast acrylic pipe, five inches in diameter. Laterals of two and four inch diameter,...

  • 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...

  • Sand pumping efficiency of a water ejector apparatus

    Creator:
    Saguanwongse, Suvat
    Abstract:
    The purpose of this investigation is to study the effect of the solid transport capacity in pumping operation: A special type of jet apparatus was investigated which emits a water jet downward counter current to delivery flow, from inside of the suction pipe toward sediment to be excavated. Two sizes...

    Abstract:
    This study was undertaken to provide information needed in the design of ocean outfalls. A review of past investigations concerning forces on submerged objects is presented. Objects independent of any boundary and cylinders in boundary contact are considered. A solution for pressure distribution about a circular cylinder resting on a...

  • Entering streamflow effects on currents of a density stratified model reservoir

    Creator:
    Elwin, Elmer Harvey
    Abstract:
    The effect of entering streamflow on currents of a density stratified reservoir has been studied in a laboratory model to provide insight into the prediction, control, and maintenance of quality water discharge from a thermally stratified reservoir. Twenty experiments were performed using various concentrations of a sodium chloride solution to...
