  • 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...

  • Patterns in stream geomorphology and implications for hyporheic exchange flow

    Creator:
    Anderson, Justin K.
    Abstract:
    Longitudinal water surface profiles from high-gradient mountain streams provide useful indicators of the relative potential for hyporheic exchange flow in stream reaches with varying morphology. The spacing between slope breaks in step-pool and pool-riffle streams provides a geomorphic scaling metric that indicates how the length of average hyporheic flow paths...

  • 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...
