  • 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...

  • 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...

  • Flows associated with harbor ship traffic

    Creator:
    Downs, Richard Allen
    Abstract:
    The purpose of this study was to ascertain the potential erosion impacts associated with ship movements in confined waters. The flow associated with a ship passage can be separated accordingly: (1) the propeller wake, (2) flow about the hull, and (3) associated waves. Each of these areas has been analyzed...

  • Seasonal variations in tidal dynamics, water quality and sediments in the Siuslaw Estuary

    Creator:
    Utt, Michael Ernest
    Abstract:
    Seasonal data on tides, water quality and sediments in the Siuslaw Estuary were collected. Tide and velocity data were analyzed to evaluate damping conditions in the estuary. The system was found to approximate a weakly damped standing wave. A strong relationship of damping conditions to river flow was observed. The...

  • 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...

  • Pressure distribution around a circular cylinder resting on a flat boundary in an oscillating fluid

    Creator:
    Johnson, Ronald Ernest
    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...

  • Behavior of stream inflows to a stratifying field reservoir

    Creator:
    Chasse, James Peter
    Abstract:
    The behavior of a stream upon entering a field reservoir was studied at various stages of stratification. The principal field techniques included fluorometric and temperature surveys. General relationships were obtained, between dimensional and locational characteristics of the inflow current and the thermal structure of the impoundment. As predicted by analytical...

    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,...
