  • 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...

  • Relationships between seasonal suspended sediment behavior and reservoir turbidity

    Creator:
    Conner, Dan Alan
    Abstract:
    The causes of turbidity in impounded and released reservoir water are studied. Seven Willamette Basin reservoirs are compared to isolate watershed and reservoir characteristics which produce variations in turbidity. Of the seven, Hills Creek Reservoir is examined in detail. Particular features of the basin and impoundment are studied to isolate...

  • 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...

  • A stochastic precipitation event model for use in erosion simulations

    Creator:
    Istok, J. D.
    Abstract:
    Mathematical models of the precipitation process are needed to effectively use historical precipitation data in the design and planning of engineering projects and for analysis of watershed runoff behavior. Existing simple models based on the assumptions of independent, identically-distributed random variables are insufficient to describe several features of the historical...

  • 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...

  • 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...

  • 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...

  • 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...

  • 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...

  • Local scour at isolated obstacles on river beds

    Creator:
    Huang, Cheng-Chang
    Abstract:
    Maximum equilibrium scour depths, equilibrium scour volumes, and induced equilibrium movements at isolated obstacles on river beds were investigated in clear-water scour. The research was achieved by a systematic flume study based on the results of dimensional analysis of local scour. The main tested obstacles for local scour were cubes....
