  • 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...

  • Stability of gravel at artificially created spawning beds in uncontrolled streams

    Creator:
    Helland-Hansen, Erik Andreas
    Abstract:
    Twenty-five gabion-type structures across the main stem and tributaries of the Siuslaw River in the Oregon Coastal Range, installed to expand the available spawning area for fish, were investigated for their ability to perform gravel control functions such as trapping bedload carried by the stream or holding gravel placed behind...

  • 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...

  • 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...

  • 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...
