  • Remote Sensing Tools for Evaluating Climate Change Impacts in Coastal Environments

    Creator:
    Herrmann, Joan F.
    Abstract:
    Climate change has pervasive impacts on Earth’s diverse ecosystems. Observed and projected effects that impact coastal environments pose unique challenges. Coastal regions provide numerous ecosystem services (e.g., fisheries, nursery habitats, erosion control, and water filtering and detoxification), house 40% of the US population, and contribute to 58% of the national...

  • Owner's Role in Brownfield Remediation : The Brownfield Experts' Perspective

    Creator:
    Saberiyan, Amireh G.
    Abstract:
    Former industrial or commercial sites that have been left unused are typically referred to as brownfield sites, or simply, brownfields. Many communities have such properties that are abandoned, idle or underused. Despite public efforts to facilitate brownfields revitalization projects, the rate of remediation remains unexpectedly slow. Efforts to resolve this...

  • A model for simulating river and reservoir temperatures with applications for anadromous fish management

    Creator:
    Currie, James William
    Abstract:
    A problem confronting the Corps of Engineers and other water resources planners in the Pacific Northwest is the prediction of anadromous fish enhancement benefits that would result from a proposed high dam project. These benefits are expected from augmenting natural streamflows with relatively cold reservoir withdrawals. The resulting increased streamflows...

  • Construction risks allocation : optimal risk allocation decision support model

    Creator:
    Alsalman, Ali Abdullah
    Abstract:
    It has been suggested that projects in the construction industry are subject to risks more than other industries. However, there is often little parity in allocation of risks in the construction industry. Usually, project participants allocate risks by aversion where owners tend to shift risks to the primary contractor, who...

  • Application of quality function deployment in the conceptual design of a construction project

    Creator:
    Hinkle, Verda O.
    Abstract:
    Quality Function Deployment (QFD) is a product development process that assures the needs and desires of the customer are heard and heeded during the design, development and production of a product. Though it has been used successfully in other industries, only a few companies in the U. S. Engineering and...

  • On Undular Bores and Solitary Waves in Variable Depth

    Creator:
    Knowles, Jeffrey N.
    Abstract:
    Numerical results are presented using a higher-order pseudo-spectral method in order to solve the Zakharov-Craig-Sulem formulation of the Euler model. We study the effects of variable bathymetry on weakly-dispersive, weakly-nonlinear, shallow water waves. Improved predictions on wave amplitude and shoaling behavior are developed by analytical means in the context of...

  • Assessment and Service Life Prediction of Microbial Induced Corrosion of Concrete (MICC)

    Creator:
    Sahan, Feyza N.
    Abstract:
    Microbial-induced corrosion of concrete (MICC) is a multi-stage deterioration process caused by microbial activity in wastewater infrastructure. MICC is a worldwide issue due to the reduced service life of the wastewater infrastructure and the economic impact associated with increased maintenance and reconstruction costs. This thesis explores two critical aspect of...

  • Effect of electron donors on the reductive dechlorination of trichlorofluoroethylene in anaerobic microcosms and in situ push-pull tests

    Creator:
    Louie, Erika N.
    Abstract:
    This research focuses on the anaerobic transformation of trichloroethylene (TCE) that is occurring in the subsurface of the Evanite site in Corvallis, OR. Two anaerobic studies were conducted to investigate the effects of microbial communities in the presence of different electron donors during the anaerobic degradation of trichlorofluoroethylene (TCFE), and...

  • A Comparison of Formation Factor to Standard Methods to Evaluate Transport Properties

    Creator:
    Whatley, Samantha N.
    Abstract:
    Chloride-induced corrosion is one of the primary causes of the degradation of reinforced steel in concrete structures. Currently, the rapid chloride permeability test (RCPT) is the most specified method to determine the concrete’s resistivity to chloride ingress, thus a determining factor in assessing the durability of concrete. While it is...

  • The effects of nail bending-yield stress and biological deterioration on the cyclic performance of shearwalls

    Creator:
    Anderson, Erin N.
    Abstract:
    Key parts of the lateral force resisting system in wood-frame buildings are the shearwafls and the connections. The connections in wooden buildings are the primary source of ductility and energy dissipation; these are essential properties when buildings are exposed to lateral forces, such as wind and earthquakes. Shearwall design is...
