  • A stochastic precipitation event model for use in erosion simulations

    Creator:
    Istok, J. D.
    Abstract:
    Mathematical models of the precipitation process are needed to effectively use historical precipitation data in the design and planning of engineering projects and for analysis of watershed runoff behavior. Existing simple models based on the assumptions of independent, identically-distributed random variables are insufficient to describe several features of the historical...

  • A preliminary assessment of post-fire dissolved organic carbon concentrations in the McKenzie River basin, Oregon

    Creator:
    Hyatt, Charles
    Abstract:
    In recent decades, the occurrence of large, high severity wildfires has increased substantially in many parts of the world, including the western United States. These fires have the potential to impact water quality, aquatic ecosystems, and downstream communities for many decades. As such, it is increasingly important to understand the...

  • Overland flow treatment of swine lagoon effluent

    Creator:
    Boda, Joseph Owen
    Abstract:
    Effluent from an anaerobic swine manure lagoon was applied at the upper end of six, 100 feet (30.5 m) long by 3 feet (0.9m) wide, grass-covered plots which sloped about 3 percent. The objectives were to measure concentration attenuation and mass reduction of potential pollutants in the wastewater as the...

  • Monitoring and Prediction of Severe Weather Phenomena through GNSS Meteorology

    Creator:
    Tahami, Hoda
    Abstract:
    While primary use of Global Navigation Satellite System (GNSS) is positioning, navigation, and timing (PNT), various GNSS applications have emerged over the past decades that includes GNSS meteorology. GNSS meteorology is the remote sensing of the atmospheric constituents in the neutral atmosphere – mostly in the troposphere - using GNSS...

  • Storm runoff response from roadbuilding and logging on small watersheds in the Oregon Coast Range

    Creator:
    Hsieh, Frederic Shu-kong
    Abstract:
    The effects of roadbuilding, logging and burning upon stream runoff responses to individual storms are evaluated for the Alsea experimental watersheds, located in the Oregon Coast Range, The parameters analyzed are peak discharge, induced peak discharge, time-to-peak, and storm-runoff volume. The volume parameter is further sub-divided into total, quick, delayed,...

  • Analysis of evapotranspiration for various climatic regimes using geostatistics

    Creator:
    Nuss, Jeffery L.
    Abstract:
    Research was conducted to determine the applicability of using the theory of regionalized variables or geostatistics in characterizing the spatial variability of reference evapotranspiration (ETr) over various climatic regimes for the state of Oregon. The state was divided into five climatic regions based on topographic features and local meteorological conditions:...

  • Chemical characterization of asphalt cements using chromatographic techniques : relation to rheological properties and field performance

    Creator:
    Thenoux, Guillermo
    Abstract:
    This dissertation presents the findings of a literature review and information regarding selection, implementation and development of a chemical composition procedure for asphalt cements. The chemical composition analysis selected was the Corbett-Swarbrick procedure standarized as ASTM D4124. The procedure is a selective adsorption / desorption (solid / liquid) chromatography which...

  • Incipient motion and particle transport in gravel-bed streams

    Creator:
    Matin, Habib
    Abstract:
    The incipient motion of sediment particles in gravel-bed rivers is a very important process. It represents the difference between bed stability and bed mobility. A field study was conducted in Oak Creek, Oregon to investigate incipient motion of individual particles in gravel-bed streams. Investigation was also made of the incipient...

  • Wave Resource Assessments: Spacio-Temporal Effect of Wave Energy Converter Scale and Blue Economy Opportunities

    Creator:
    Dunkle, Gabrielle R.
    Abstract:
    Wave energy has the potential to power large and small factions of economies around the world alike. Current methods for determining the amount of wave energy resource available to wave energy converter (WEC) devices entail capturing the look of the sea state at large by presenting characteristic wave heights, periods,...
