  • Physical Modeling of Progressive Damage and Failure of Wood-Frame Coastal Residential Structures Due to Waves and Surge Forces

    Creator:
    Duncan, Sean M.
    Abstract:
    A physical model study was performed to examine the forces and response of 1:6 scale wood-frame coastal residential structures subjected to storm surge and waves. An on-grade and an elevated specimen were tested and exposed to regular waves with varying water depths and wave heights to simulate Hurricane Sandy’s conditions....

  • Prototype-Scale Physical Model Study of Wave Attenuation by an Idealized Mangrove Forest of Moderate Cross-shore Width

    Creator:
    Kelty, Kiernan M.
    Abstract:
    The use of natural and nature-based features for coastal hazard mitigation, particularly emergent vegetation such as mangrove forests, have become increasingly popular. However, the protection that these systems can provide has not been fully quantified for engineering design, and the uncertainties in parameterized equations have not been fully defined. In...

  • Height Modernization from Static GPS Networks in Oregon: Evaluating NGS Guidelines and OPUS-Projects

    Creator:
    Kerr, Darren J.
    Abstract:
    Determining accurate elevations is important for many engineering and scientific applications, and finding these heights via GNSS increases efficiency and significantly reduces the costs as compared to precise geodetic leveling. The National Geodetic Survey (NGS) has published guidelines for determining both ellipsoidal and orthometric heights with GPS to within 2...

  • Bridge Damage State Detection Based on Strain-Based Wireless Structural Health Monitoring

    Creator:
    Slaven, Kelli R.
    Abstract:
    The Pacific Northwest is at risk for significant seismic and tsunami events, which are capable of severely damaging lifeline transportation infrastructure, particularly bridges. As the bridges in the United States age and begin to show signs of fatigue, the risk for severe damage increases. Proper monitoring and inspection of bridges...

  • Probabilistic Tsunami Hazard and Damage Assessment of the Built Environment : Applied at Seaside, Oregon

    Creator:
    Park, Hyoungsu
    Abstract:
    Damage estimates to the built environment from tsunamis are important for disaster mitigation, including planning emergency response and recovery. This dissertation evaluates the damage states of buildings in a small urban coastal city, Seaside, Oregon, from tsunami hazards generated by a Cascadia Subduction Zone (CSZ) event. This study is separated...

  • Evaluation of Topography and Seismicity on Shallow Landslide Susceptibility

    Creator:
    Hess, Daniel M.
    Abstract:
    Shallow landslides are a prevalent concern in mountainous regions that can result in severe societal, economic, and environmental impacts. The challenge is further compounded as the size and location of a potential slide is often unknown. This study presents a generalized approach for the evaluation of shallow landslide susceptibility using...

  • Tsunami inundation : estimating damage and predicting flow properties

    Creator:
    Wiebe, Dane Michael
    Abstract:
    The 2004 Indian Ocean and 2011 Tohoku tsunami events have shown the destructive power of tsunami inundation to the constructed environment in addition to the tragic loss of life. A comparable event is expected for the Cascadia Subduction Zone (CSZ) which will impact the west coast of North America. Research...

  • Hydraulic experiments on impact forces from tsunami-driven debris

    Creator:
    Ko, Harrison T.
    Abstract:
    Impact by an idealized shipping container on a column were observed for tsunami flow in a large-scale wave flume modeled at the O.H. Hinsdale Wave Research Laboratory at Oregon State University. Two specimen types, aluminum and acrylic, were tested; and each specimen was tested in two orientations, longitudinal and transverse....

  • Performance-Based Design Methodology for Using Emergent Vegetation to Mitigate Wave Overtopping

    Creator:
    Ostrow, Kayla
    Abstract:
    To facilitate the design of Natural and Nature-Based Features (NNBF) for flood protection, this thesis expands an existing engineering design methodology to NNBF systems. The existing approach is a Level III reliability method for the performance-based design of traditional coastal engineering systems. The expanded methodology incorporates uncertainties inherent to both...

  • Observations and prediction of intermittent sediment suspension in the surf zone

    Creator:
    Yoon, Hyun Doug
    Abstract:
    In this dissertation the interactions between hydrodynamics, sediment suspension and transport, and morphological evolution in the surf zone was investigated with a large-scale laboratory experiment data, CROss-Shore Sediment Transport Experiment (CROSSTEX). The data set included comprehensive measurements of water surface elevation, fluid velocity, sediment concentration, and morphology for irregular waves...
