  • Trends in college news : a comparative study of Oregon State College news in the Oregonian and Oregon Journal for a 15-year period

    Creator:
    Shideler, Fred Merle
    Abstract:
    This study of the Oregon State college news appearing in the Oregonian and Oregon Journal in Portland at five-year intervals over a 15-year period was undertaken primarily to attempt to determine, if possible, trends in college news; to indicate the emphasis on different types of college news; to determine the...

  • Hydrology of five forest roads in the Oregon Coast Range

    Creator:
    Marbet, Christine Erica
    Abstract:
    Understanding the impact of low volume road networks on forested watersheds is important for future forest management and watershed restoration. This study characterized the hydrology of five segments of forest road in the Oregon Coast Range. Rainfall, infiltration, road surface runoff, and intercepted subsurface flow were measured at each road...

  • The Effects of Biofilm on Sandy Soil Hydrology

    Creator:
    Runion, Danielle N.
    Abstract:
    It is known that soil biota affects water dynamics through various complex mechanisms. The impact on retention by soil biota are due to a combination of changes to pore geometry, pore clogging by biofilms, biofilms that serve to connect thin water films across many pores as the soil dries, and...

  • Subglacial hydrology of the Lake Michigan Lobe, Laurentide Ice Sheet

    Creator:
    Breemer, Christopher W.
    Abstract:
    Fast ice flow and unstable ice sheet behavior were characteristic features of the Lake Michigan Lobe of the southern Laurentide Ice Sheet. Such behavior may result from some combination of subglacial-sediment deformation and decoupled sliding at the ice-bed interface. Both mechanisms depend on high water pressure relative to ice pressure....

  • The Ibis, journal of the British Ornithologists' Union : a pre-synthesis portrait

    Creator:
    Johnson, Kristin Renee
    Abstract:
    In 1959 the British Ornithological journal, The Ibis, published a centenary commemorative volume on the history of ornithology in Britain. Over the previous few decades, the contributors to this volume had helped focus the attention of ornithologists on the methods, priorities, and problems of modem biology, specifically the theory ofevolution...

  • Hydrology and delineation in four wetlands in the Oregon Cascades

    Creator:
    MacLeod, Norman A.
    Abstract:
    Four wetland sites were identified and delineated in Silver Falls State Park, Oregon using procedures outlined in the 1989 Federal Manual for the Identification and Delineation of Jurisdictional Wetlands and subsequently monitored for a ten month period. A network of 225 shallow (32") wells was installed throughout the sites to...

  • Control circuitry for a telemetry system

    Creator:
    Hespelt, George Gordon
    Abstract:
    This thesis describes the control circuitry for a telemetry system developed to report hydrologic information from remote locations. The multiparameter, on-call system operates on a single frequency. Each remote station responds to a predetermined number of pulses from the master station. Data is transmitted by pulse- duration modulation. In the...

  • Forest road hydrology : the influence of forest roads on stream flow at stream crossings

    Creator:
    Toman, Elizabeth Myers
    Abstract:
    The management of existing forest road systems is an issue of growing importance and public debate. Roads can alter the hydrologic processes in a watershed especially at stream crossing culverts where road ditches channel runoff directly into the stream. The objective of this study was to determine how surface runoff...

  • Bridging Data and Theory: Developing Physics Informed Machine Learning for Snow Hydrology

    Creator:
    Steele, Hannah
    Abstract:
    Snow is a critical component of global climate regulation and provides water resources to over one billion people worldwide. Yet current measurement methods and modeling techniques lack the ability to fully capture snow characteristics such as snow water equivalent (SWE), snow depth, and density variable landscapes. In recent years, the...
