  • Spatial and temporal runoff response to snowmelt, and the influence of geomorphology in a headwater catchment, central eastern Cascades, Washington

    Creator:
    Alley, David
    Abstract:
    This report presents a nested gauging study of streamflow variability from three sub-catchments (150-200 ha in area) of the Burns Creek catchment (565 ha) in the Entiat Experimental Forest of central Washington State. We test and reject the hypothesis that headwater catchments of this size are composed of physically and...

  • Hillslope hydrology : from patterns to processes

    Creator:
    Tromp-van Meerveld, Hilda J.
    Abstract:
    This dissertation re-examines the now standard perceptual model of hillslope hydrological response to rainfall, which includes the growth of a saturated wedge at the soil-bedrock interface or impeding layer. It also challenges the notion of bedrock impermeability and the assumption that the pattern of subsurface stormflow is determined by the...

  • 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...

  • 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...

  • Inter-relationships of vegetation, hydrology and micro-climate in a young, Douglas-fir forest

    Creator:
    Barnard, Holly Rene
    Abstract:
    The links between forests, streamflow, and climate are poorly understood. Despite hundreds of studies over the past 60 years, fundamental questions of forests' effects on the hydrologic cycle remain unanswered. The hydrological cycle involves mutually-dependent biological and physical processes that operate at multiple scales of time and space, and this...
