  • Sustainable construction safety and health rating system

    Creator:
    Rajendran, Sathyanarayanan
    Abstract:
    The main objective of this research study is to incorporate construction worker safety and health into sustainable design and construction practices. This can be fulfilled by the development of an innovative construction worker safety and health planning tool, called Sustainable Construction Safety and Health (SCSH) Rating System that will: •...

  • Spatial, diel and seasonal variations in dissolved oxygen and temperature within a stratified lake

    Creator:
    Smith, Stanley Allan
    Abstract:
    Spatial, diel and seasonal variations in dissolved oxygen and temperature were measured in Triangle Lake, Oregon. Spatial dissolved oxygen and temperature variations measured in the stratified lake are presented to illustrate the horizontal uniformity of the lake and to demonstrate the applicability of the one dimensional assumption for sampling and...

  • Using the predictive method in the 2010 Highway Safety Manual to identify hazardous intersections in Corvallis, OR

    Creator:
    Zhou, Yanfen
    Abstract:
    An intersection, due to its vehicle and pedestrian conflict movements, experiences complex traffic situations that might contribute to crashes. In the city of Corvallis, OR, historically more than 80% of the total crashes have occurred within an intersection or have been designated as intersection-related. It is important to develop a...

  • Determination of structural layer properties of aggregate and asphalt surfaced roads

    Creator:
    Rwebangira, T.
    Abstract:
    This study involved the determination of the structural layer properties of aggregate and asphalt surfaced pavements for use in the evaluation of pavement load carrying capacity and the seasonal effects of moisture. This was achieved by the use of Nondestructive Testing Methods (NDT) and backcalculation techniques. Pavement surface deflection measurements...

  • Seismic Performance of Aging Prestressed Transmission Pole with Simulated Soil Foundation

    Creator:
    Argo, Maximo
    Abstract:
    The Cascadia Subduction Zone has recently been identified as a source for an impending great earthquake. The potential of a large earthquake has created widespread interest into the resiliency of lifelines within the potentially affected areas. One critical lifeline is the electrical distribution and transmission systems which relies on legacy...

  • Demonstration of a permeable barrier technology for the in-situ bioremediation of pentachlorophenol contaminated groundwater

    Creator:
    Cole, Jason David
    Abstract:
    A pilot scale demonstration of a biological permeable barrier was conducted in a pentachlorophenol-contaminated aquifer at a wood preserving facility. A permeable reactor was constructed to fit within a large diameter well. Arranged in series, a cylindrical reactor 24" x 36" (0.61 x 0.91m) (diameter x height) was partitioned to...

  • 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:...

  • Application of geostatistics to regional evapotranspiration

    Creator:
    Amegee, Kodjo Y.
    Abstract:
    Regionalized variable analysis has been used to study a number of meteorological and hydrological variables including precipitation (Delhomme and Delfinier, 1973), streamfiow (Villeneuve et al., 1979) and hydraulics of groundwater aquifers (Gambolati and Volpi, 1979). In the research work reported in this thesis, an attempt was made to characterize the...

  • Input/output energy analysis of regional water pollution control

    Creator:
    Heggen, Richard J.
    Abstract:
    Two strategic approaches to water quality control in Oregon's Willamette River are presently being utilized: point source treatment and flow augmentation. Dry weather releases from reservoirs are for authorized purposes other than water quality. Reservoirs can participate in pollution control by summer flow augmentation where authorized water resource objectives (flood...

  • The evaluation and selection of highway safety improvements for local jurisdictions

    Creator:
    Haq, Asif Jinnah
    Abstract:
    Many hazardous locations exist on our local and street highway systems. Such hazards contribute to the frequency and severity of traffic accidents. The elimination and mitigation of the hazards reduces accident frequency and severity, as measured by the number of fatalities, injuries and property damage resulting from the accidents. The...
