  • 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,...

  • 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...
