  • 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...

  • 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...

  • 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...

  • 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...

  • The effect of boundary geometry on internal density currents in a density stratified reservoir

    Creator:
    Spurkland, Torbjorn
    Abstract:
    The effects of boundary geometry on internal density currents in a density stratified reservoir were investigated in a laboratory model. When water was simultaneously withdrawn and admitted to the reservoir, a complex current regime was established. The general flow pattern is described, and the influence of physical variables on the...

  • Ambient current effects on vertical selective flow withdrawal in a two layer reservoir system

    Creator:
    Charbeneau, Randall Jay
    Abstract:
    Withdrawal from a two-layer flow field is examined in terms of the degree of selectivity of the withdrawal flow and its dependence on an ambient current. Selectivity is defined as the bias of withdrawing one layer more strongly than the other; the extreme' case is complete selective withdrawal, where one...

    Creator:
    Higgins, Bruce John
    Abstract:
    An interesting means of shoal removal has recently been implemented by the U.S. Army Corps of Engineers for use in shallow Pacific Coast tidal inlets and estuaries. In the past, removal of shoaled material has consisted of physical excavation of material, transportation from the site, and placement in a spoils...

  • 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,...

  • 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...

  • 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...
