  • 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...

  • Hydraulic influences on pool morphology : a laboratory investigation

    Creator:
    Frizenschaf, Jacqueline
    Abstract:
    A flume study was conducted to investigate the influences of changing hydraulic conditions on the bed morphology of a scoured pool. During a simulated storm runoff event, responses of the pool were tested under different conditions: clearwater flow, sediment supply at steady rates, and two different sediment mixtures of the...

  • Consumptive use of surface water by Willamette Basin municipalities

    Creator:
    Mittelstadt, Richard Lee
    Abstract:
    The consumptive water use of six cities in the Willamette Basin of northwestern Oregon was evaluated for the period 1960-66. Consumptive use ratios were obtained by analyzing data from monthly water supply and sewage flow records. The average annual consumptive use for the six cities was found to be 26...

  • Modeling sediment transport, channel morphology and gravel mining in river bends

    Creator:
    Nam, Ilgi
    Abstract:
    A technique is developed and tested to analyze the interaction of flowing water, bed topography, and bedload sediment transport in meandering channels where gravel bars are removed. The method relates the local velocity distribution, bed shear stress and sediment transport conditions to the local bed configuration in river bends before...

  • Prediction of monthly streamflows for Oregon coastal basins using physiographic and meteorological parameters

    Creator:
    Orwig, Charles Edwin
    Abstract:
    Prediction equations were developed for estimating the flow regime at ungaged stream locations in the Oregon coastal range. Principal components analysis was used to screen the initial data set of physiographic and meteorological parameters. The final regression equations for predicting mean monthly flow had standard errors of estimate ranging from...

  • Incipient motion and particle transport in gravel-bed streams

    Creator:
    Matin, Habib
    Abstract:
    The incipient motion of sediment particles in gravel-bed rivers is a very important process. It represents the difference between bed stability and bed mobility. A field study was conducted in Oak Creek, Oregon to investigate incipient motion of individual particles in gravel-bed streams. Investigation was also made of the incipient...

  • Storm runoff response from roadbuilding and logging on small watersheds in the Oregon Coast Range

    Creator:
    Hsieh, Frederic Shu-kong
    Abstract:
    The effects of roadbuilding, logging and burning upon stream runoff responses to individual storms are evaluated for the Alsea experimental watersheds, located in the Oregon Coast Range, The parameters analyzed are peak discharge, induced peak discharge, time-to-peak, and storm-runoff volume. The volume parameter is further sub-divided into total, quick, delayed,...

  • Incipient resuspension of silt-clay deposits in oscillatory and unidirectional flows

    Creator:
    Talebbeydokhti, Nasser
    Abstract:
    Incipient motion of cohesive sediment and the role of flow parameters were investigated for separate and combined unidirectional and oscillatory flows. Sediment from Sturgeon Lake, mainly silt and clay with organic matter, was used as bed material In recirculating and wave flumes. Bench-type experiments indicated that when the submerged sediment...

  • Sediment transport in a gravel-bottomed stream

    Creator:
    Milhous, Robert T.
    Abstract:
    Sediment transport in a gravel-bottomed stream located in the Oregon Coast Range was studied to determine the effects of a single layer of large particles (the armour layer) located at the surface of the bed material. The bed load transport system was studied jointly with suspended sediment transport to understand...
