  • 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...

  • Scourability of weak rock in the Oregon Coast Range

    Creator:
    Baillie, Michael W.
    Abstract:
    The undermining of bridge foundations can lead to either costly repairs or a bridge collapse. These foundations must be designed to counter the effects of scour. Current practice does not allow for accurate estimates of scour in erodible rock. Scour in rock can be related to geotechnical and hydraulic properties....

  • 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...

  • Moisture effects on properties of wood-composite assemblies

    Creator:
    King, David
    Abstract:
    Engineered wood composites are used in many structural applications and are intended for dry use. However, these materials may encounter significant amounts of wetting while in service, which can lead to structural failures. This study combined aspects of wood science, mechanics, structural engineering, and mycology to assess changes in material...

  • 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...

  • 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:...

  • Modeling shallow-water hydrodynamics : rotations, rips, and rivers

    Creator:
    Long, Joseph W.
    Abstract:
    Hydrodynamic models are used as a diagnostic tool to understand the temporal variability of shallow-water processes that are difficult to completely resolve with traditional field measurements. For all simulations, modeled quantities are qualitatively or quantitatively compared with available measurements to gain confidence in conclusions derived from the modeled results. In...

  • Initial performance assessment for implementation of hot mix asphalt containing recycled asphalt shingles in Oregon

    Creator:
    Samoo, Faisal Ahmed
    Abstract:
    This thesis documents the evaluation of the initial performance of pavement containing recycled asphalt shingles (RAS) in Oregon. The research was funded by the Oregon Department of Transportation (ODOT) and the Federal Highway Administration and was conducted at Oregon State University. The key objectives of this thesis are to document...

  • A Methodological Approach for Structural Health Monitoring of Mass-Timber Buildings Under Construction

    Creator:
    Baas, Esther J.
    Abstract:
    As mass-timber building construction rises around the globe, there exists the need to verify the long-term, in-situ behavior and performance of these structural systems. Structural health monitoring (SHM), generally defined as a damage detection strategy consisting of a network of sensors, a data acquisition system, and algorithms for data analysis,...
