  • 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...

  • Measuring sediment transport rates using tracer gravel and RFID technology

    Creator:
    Lewis, Logan L.
    Abstract:
    Rates of sediment transport were determined using tracer gravel and a RFID antenna array at Oak Creek (Oregon) to compare a new method with an existing transport relation created from data previously collected in the same study reach. Close to 3,000 tracers were deployed throughout the study reach and were...

  • Dam removals and downstream bar-pool morphology

    Creator:
    Zunka, John Page Purnell
    Abstract:
    Bar-pool morphology in rivers can provide vital habitat to aquatic species, notably salmonids, which require gravel riffles to bury eggs and pools for hydraulic and cold-water refuge. In some cases, the erosion and subsequent deposition of coarse sediment downstream of a dam removal can modify habitat by inundating bar-pool structure,...

  • Controls on Process and Form in Alluvial and Bedrock Meandering Rivers

    Creator:
    Zunka, John P. P.
    Abstract:
    Bedrock meandering rivers are sinuous channels that pair steep bedrock outside banks with lower gradient slip-off slopes on the inside of bends. These rivers have the potential to record information on climatic and tectonic “external” forcings in their morphology (e.g., longitudinal profiles, strath terraces, channel and valley dimensions). However, geology...
