  • An analysis of wave forces on prototype walls under tsunami loading

    Creator:
    Oshnack, Mary Elizabeth
    Abstract:
    This thesis is comprised of two manuscripts based on a laboratory experiment conducted to examine realistic wave forcing on a vertical wall subjected to tsunami loading. The first manuscript examined tsunami force and pressure distributions on a rigid wall that was fronted by a small seawall. Six different seawall heights...

  • Laboratory observations of tsunami runup on a complex 3D bathymetry using PIV

    Creator:
    Ichikawa, Shingo
    Abstract:
    This thesis presents the details of a large-scale laboratory experiment to study the runup velocity on a complex 3D bathymetry. The PIV measurements including the instrumental setup, the recording procedure, and the image processing are presented. Tsunami inundation directly affects the coastal population and is one of the most important...

  • Design and implementation of a physical model for Keystone Harbor, WA

    Creator:
    Richmond, J. Brady
    Abstract:
    Strong tidal currents experienced at Keystone Harbor, WA, have caused navigational hazards and disrupted ferry service in the area. This thesis presents details of the design, construction and implementation of a large scale physical model of Keystone Harbor used to evaluate the effectiveness of proposed jetty design alternatives to improve...

  • 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...

  • 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....

  • 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....

  • The Effects of Debris Loading on the Performance of a Tsunami Evacuation Building for Life Safety

    Creator:
    Snyder, Snyder
    Abstract:
    In recent years, tsunami events have caused great devastation and loss of life around the globe. The coast of Oregon is highly vulnerable to a nearfield tsunami event caused by a Cascadia Subduction Zone earthquake, yet lacks a clear plan for evacuation and disaster mitigation. Vertical evacuation is a proposed...

  • 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...

  • Laboratory Observations of Tsunami-Driven Debris Damming with Comparison to ASCE 7-22 Minimum Design Loads

    Creator:
    Doyle, Kellen C.
    Abstract:
    Tsunami inundation of coastal communities can impose a wide array of forces on the built environment. Forces generated by tsunami-driven debris damming have the potential to cause failure of coastal structures and further accumulate flow-entrained debris. Since tsunami-resilient design standards were adopted by ASCE in 2016, debris damming considerations have...

  • Experimental and numerical modeling of wave height attenuation by emergent coastal vegetation

    Creator:
    Blackmar, Philip James
    Abstract:
    Coastal vegetation dampens waves which can provide benefits to the local area, but existing literature shows large variations in the degree of wave height attenuation depending on plant properties and wave conditions. Better knowledge of how to predict the wave height decay accurately in different types of vegetation may help...
