  • Measurement and modeling the physical controls of snowmelt in the Pacific Northwest

    Creator:
    Mazurkiewicz, Adam B.
    Abstract:
    The physical controls of snowmelt in the Pacific Northwest (PNW) are poorly understood. While there have been numerous field and modeling investigations at the plot and watershed scale, few studies have identified how the snow energy balance (EB) components vary in importance both spatially and temporally. The identification of how...

  • Water residence time and runoff generation in the western Cascades of Oregon

    Creator:
    McGuire, Kevin J.
    Abstract:
    The age, or residence time of water is a fundamental descriptor of catchment hydrology, revealing information about the storage, flow pathways and source of water in a single integrated measure. While there has been tremendous recent interest in residence time to characterize catchments, there are few studies that quantify residence...

  • Hydro-biogeochemical coupling at the hillslope and catchment scale

    Creator:
    van Verseveld, Willem J.
    Abstract:
    The specific objectives of this dissertation are to determine subsurface flow behaviors across different antecedent wetness conditions from a top-down perspective and to mechanistically assess the hydrological controls on DOC and N transport at the hillslope and catchment scale. The study area is a small catchment where hillslopes issue directly...

  • The role of bedrock groundwater in rainfall-runoff response at hillslope and catchment scales

    Creator:
    Gabrielli, Christopher P.
    Abstract:
    Bedrock groundwater dynamics in headwater catchments are poorly understood and poorly characterized. Direct hydrometric measurements have been limited due to the logistical challenges associated with drilling through hard rock in steep, remote and often roadless terrain. Here we develop and use an inexpensive, portable bedrock drilling system to explore bedrock...

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

    Creator:
    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...
