  • 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...

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

    Creator:
    McKenzie, David Roller
    Abstract:
    During 1973 data was collected to analyze the seasonal variations of the tidal dynamics, water quality and sediments of the Alsea Estuary. A summary of historical information with a list of all known alterations to the estuary was made. A complete physical description, including the geographical setting and mixing classification...

  • 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...

  • Tsunami propagation in large rivers : idealized cases and the Columbia River Estuary

    Creator:
    Kalmbacher, Kirk D.
    Abstract:
    The hazards associated with tsunamis are well known and have been studied for decades. The majority of research is, however, focused on open coastlines which bear the brunt of a tsunamis force. Other regions that can be strongly impacted by a tsunami are large estuaries. Here, the tsunami encounters a...

  • 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...

  • Modeling estuary pollution by computer simulation

    Creator:
    Grenney, William J.
    Abstract:
    A digital computer model was developed to simulate the time and space distribution of a dissolved pollutant in an estuary. The program is basically a one-dimensional finite-difference model, but two dimensions can be represented by attaching together several one-dimensional channels. The influence of convection, dispersion and decay are included in...

  • Plans and Specifications for a Sewerage System for all of Corvallis Lying West of Ninth Street

    Creator:
    Gardner, Wilford W.
    Abstract:
    At the present time only a portion of Corvallis is sewered and a portion of the city still employs the most crude and unhealthful methods of disposal. The district east of Ninth Street, as shown on the map, has an effective system of well constructed sewers, of the combined storm-water...

  • Tidal influence on downstream fining in gravel-bed rivers

    Creator:
    Coles, Derron Rafiq
    Abstract:
    This research examines the downstream fining phenomenon as it operates in coastal gravel-bed rivers of Oregon. Downstream fining is a change in bed composition toward smaller sediment sizes in the downstream direction. Changes in stream flow discharge and channel slope affect the rate of bed-load transport, thereby altering the downstream...

  • Estuarine tidal hydraulics : one dimensional model and predictive algorithm

    Creator:
    Goodwin, Carl R.
    Abstract:
    A one-dimensional, implicit, finite-difference model is developed, calibrated and verified for three estuaries along the central Oregon coast. The model is used to generate controlled data for a large number of hypothetical estuaries. Two non-dimensional coefficients, K[subscript F], and. K[subscript I], are developed incorporating physical characteristics of the estuary which...

    Baliga, B. R. (B. Ravindranath)
    Abstract:
    The stochastic and the Fourier theories for sand waves developed by Lee(11) and Hino(6), respectively, for unidirectional flows are extended in order to estimate the rate of sediment turnover (RST) under oscillatory flows in the South Slough estuary, Coos Bay, Oregon. Data were collected by a mechanical and a sonic...
