  • Flux of ground water and nitrogen through the floodplain of a fourth-order stream

    Creator:
    Wondzell, Steve
    Abstract:
    Changes in the concentrations of dissolved ammonia (NH4+1), nitrate (NO3-1), organic nitrogen (DON) were monitored along ground water flow paths to determine the importance of the ground water system to the stream nitrogen budget. The study site was located on a wide floodplain along a fourth-order stream in the Oregon...

  • 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...
