  • Large-scale laboratory observations of wave breaking turbulence on a fixed barred beach

    Creator:
    Scott, Christopher P.
    Abstract:
    This thesis presents the details of a large-scale laboratory experiment to study the turbulence generated by waves breaking on a fixed barred beach. The data set includes comprehensive measurements of free surface displacement and fluid velocity for one random and one regular wave case. Observations of the time-averaged turbulent kinetic...

  • 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...

  • 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....

  • Effects of Wave Nonlinearity and Vertical Variation of Vegetation Density on Wave Attenuation

    Creator:
    Wu, Wei-Cheng
    Abstract:
    The understanding and prediction how coastal wetland vegetation attenuates wave action has received renewed attention with global climate change impacts and increasing populations on coastlines. Conventional attenuation models utilize empirical drag coefficients, but these coefficients exhibit a wide range of values, and there is some uncertainty in the relative importance...

  • 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...

  • 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...

  • Nowcast/forecast of storm surge and drawdown using a hybrid FE/ANN approach

    Creator:
    Darnell, Joel T.
    Abstract:
    In the northwestern Gulf of Mexico there is a need for reliable water level forecasts to facilitate safe commercial navigation, marine construction, and emergency management. Though the low amplitude tides of the region can be predicted with conventional harmonic techniques, frequent strong storms make accurate forecasts of water levels difficult....

  • Describing Tsunami Inundation and Debris Motion using Optical Measurement Methods in a Large-Scale Wave Basin

    Creator:
    Rueben, Matthew Robert
    Abstract:
    This thesis consists of two papers in manuscript format. The first paper presents optical measurements of tsunami inundation through an urban waterfront in a laboratory wave basin. The physical model was constructed at 1:50 scale and was an idealization of the town of Seaside, Oregon. The paper presents an analysis...

  • Developing tools to improve tsunami resilient design of coastal structures

    Creator:
    Thomas, Seth Alan
    Abstract:
    Over the last decade the world has seen three major tsunamis strike the coasts of Indonesia, Samoa, and Chile. These tsunamis have caused significant losses of life and property on the coastal cities of these and nearby countries. The NEES (Network for Earthquake Engineering Simulation) Housesmash project was created to...

    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....
