  • Wave-current interaction induced by standing long waves in the surf zone

    Creator:
    Phaksopa, Jitraporn
    Abstract:
    This dissertation has focused on the charateristics of bubbles generated by breaking waves and the feedback of wave-current interaction on the forcing mechanism of low frequency wave especially basin seiching wave. For the first study, Optical image capture observations of breaking waves in a laboratory surf zone are presented. The...

  • 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...

  • Understanding the Similarities and Differences Between Academia and the Engineering Workplace through Barriers to Adoption, Epistemic Beliefs, and Problem-Solving Behavior

    Creator:
    Gestson, Sean Lyle
    Abstract:
    Engineering education research has led to a greater understanding of the gap in preparedness of students for the engineering industry. Multiple studies comparing the workplace and academic contexts and the participants in those contexts (i.e., students, faculty, and engineering practitioners) have emphasized similarities and differences between the two contexts by...

  • Ultimate and serviceability limit state reliability-based axial capacity of deep foundations

    Creator:
    Reddy, Seth C.
    Abstract:
    Deep foundations are necessary for the construction of many structures, such as bridges and buildings, located in areas unsuitable for shallow foundations. Owing to the inherent variability of soil and the complex changes that occur in the soil adjacent to deep foundations as they are installed, the ability to accurately...

  • Tsunami-induced Soil Instability

    Creator:
    Fischer, Rachael Marie
    Abstract:
    Recent tsunami field surveys from the 2011 Great East Japan Earthquake and Tsunami have recorded numerous examples of tsunami-induced soil instability: significant scour around foundations, foundation failure of piles, and other damage caused by liquefaction. From the observations of soil instability leading to the failure of critical coastal structures, it...

  • Tsunami Simulation Using OpenSees : Validation of Bridge Response and Exploration of Shallow Water Flow

    Creator:
    Cressman, Luke R.
    Abstract:
    The finite element software framework, OpenSees, has been used by researchers to simulate the response of structural and geotechnical systems to earthquake loading. Implementation of the Particle Finite Element Method (PFEM) has made it possible to simulate hydrodynamic forces through fluid-structure interaction (FSI) in OpenSees. To validate the FSI implementation...

  • Tsunami propagation in large rivers : idealized cases and the Columbia River Estuary

    Creator:
    Kalmbacher, Kirk D.
    Abstract:
    The hazards associated with tsunamis are well known and have been studied for decades. The majority of research is, however, focused on open coastlines which bear the brunt of a tsunamis force. Other regions that can be strongly impacted by a tsunami are large estuaries. Here, the tsunami encounters a...

  • Tsunami loading on light-frame wood structures

    Creator:
    Linton, David B.
    Abstract:
    Since 2004 there have been multiple devastating tsunamis around the globe triggered by large magnitude earthquakes; with the most recent being the Tohoku, Japan tsunami in March 2011. These tsunamis have caused significant loss of life and damage to the coastal communities impacted by these powerful waves. The resulting devastation...

  • Tsunami Loading on Coastal Infrastructure

    Creator:
    Xie, Zhongliang
    Abstract:
    The safety of coastal infrastructure has been a concern after the Indian Ocean Tsunami in 2004 and the Great East Japan Tsunami in 2011. The western coast of the United States is also exposed to tsunami hazards due to the Cascadia subduction zone. Therefore, it is critical to design coastal...

  • 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...
