  • Patterns and processes of sediment transport following sediment-filled dam removal in gravel bed rivers

    Creator:
    Stewart, Gregory B.
    Abstract:
    Dam removal is increasingly viewed as a river restoration tool because dams affect so many aspects of river hydrology, geomorphology, and ecology; but removal also has impacts. When a dam is removed, sediment accumulated over a dam’s lifetime may be transported downstream; and the timing, fate and consequences of this...

  • Sediment Pulse Behavior in Gravel-bedded Rivers

    Creator:
    Pace, Kylie M.
    Abstract:
    As dams approach the end of their useful life, there is need to predict where and how accumulated sediment will move following their removal to estimate impacts on aquatic habitat and infrastructure. Flume studies suggest that sediment pulses disperse in place for most dams, but it is hypothesized that a...

  • Stream channel stability and sensitivity to landscape history and land use changes in Kelley Creek, Portland, Oregon

    Creator:
    Murphy, Yarrow M.
    Abstract:
    This study examines stream channel erosion processes in a small urbanizing watershed influenced by deposits of the Columbia Basin catastrophic floods: Kelley Creek, a 12-km² tributary of Johnson Creek, located just east of Portland, Oregon. Information on landscape history, stream channels, and sediment dynamics was compiled. The effects of future...
