  • Patterns of sediment accumulation in the Siletz River Estuary, Oregon

    Creator:
    Pakenham, Anna
    Abstract:
    Anecdotal evidence suggests many Pacific Northwest estuaries are filling with sediment due to historical logging activities in upstream watersheds. Using the Siletz River estuary as a case study, this research began by analyzing timber harvest and discharge records of the Siletz River watershed, and found that increased timber harvest coincides...

  • Beyond the paired-catchment approach : isotope tracing to illuminate stocks, flows, transit time, and scaling

    Hale, V. Cody
    Abstract:
    This dissertation integrates a process-based hydrological investigation with an ongoing paired-catchment study to better understand how forest harvest impacts catchment function at multiple scales. We do this by addressing fundamental questions related to the stocks, flows and transit times of water. Isotope tracers are used within a top-down catchment intercomparison...
