  • Development of a guideline for estimating tsunami forces on bridge superstructures

    Creator:
    Boon-intra, Sutaporn
    Abstract:
    Infrastructures along the Oregon Coast are vulnerable to seismic events in the Cascadia Subduction Zone that could generate large tsunamis. Bridges along the coast are an important part of the transportation and lifeline system in the area. The major damages on these bridges due to earthquake and/or tsunami would result...

  • Extreme Wave Runup and Runup Variability on Beaches

    Creator:
    Li, Chuan
    Abstract:
    Wave runup is an important physical process that affects nearshore sediment transport, coastal erosion, and flooding. Large and unexpected runup events can also be dangerous to beach goers. Extreme runup statistics are essential parameters used in engineering design of marine structures and in coastal management. Although the study of runup...

  • From Perception to Planning : Adaptation in Flood-risk Communities

    Creator:
    Gomez, Luis A.
    Abstract:
    This research asserts that flood risk perception of individuals living in floodplains influences their preparedness for taking actions to protect themselves from flood hazards. The results of this research are backed up by quantitative analysis of survey responses of individuals living in floodplains of Corvallis, OR in the USA. The...

  • Development of Practical Accelerated Testing Protocols for the Performance Evaluation of Concrete against Microbially Induced Corrosion of Concrete

    Creator:
    Erbektas, Ali Riza
    Abstract:
    Sustainable wastewater infrastructure systems are vital for civilizations to protect public health. Most of the structural elements of wastewater infrastructure are constructed using concrete owing to its versatility, low cost, and durability. Concrete structures that are exposed to wastewater can experience Microbially Induced Corrosion of Concrete (MICC), which is a...

  • Breaking Waves Offshore: Measurements and Modeling of Energy Dissipation

    Creator:
    Ticona Rollano, Fadia M.
    Abstract:
    In the presence of strong winds, ocean surface waves dissipate significant amounts of energy by breaking. Here, breaking rates and wave-following turbulent dissipation rate measurements are compared with numerical WAVEWATCH III estimates of bulk energy dissipation. At high winds, the measurements suggest that turbulent dissipation becomes saturated, however the modeled...

  • Input/output energy analysis of regional water pollution control

    Creator:
    Heggen, Richard J.
    Abstract:
    Two strategic approaches to water quality control in Oregon's Willamette River are presently being utilized: point source treatment and flow augmentation. Dry weather releases from reservoirs are for authorized purposes other than water quality. Reservoirs can participate in pollution control by summer flow augmentation where authorized water resource objectives (flood...

  • 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...

  • Radar and Optical Remote Sensing of Submesoscale Frontal Features

    Creator:
    Simpson, Alexandra J.
    Abstract:
    The coastal region is home to many types of surface fronts that exist on a submesoscale (1-10 $km$). While in situ observations capture point or transect observations of frontal behavior subsurface, their complex spatial patterns can be well-captured using remote sensing techniques, which provide synoptic views of the ocean surface...

  • Tsunami and hurricane wave loads on bridge superstructures

    Creator:
    Azadbakht, Mohsen
    Abstract:
    This dissertation examines tsunami and hurricane wave loads on bridge superstructures. Tsunamis have caused significant damage to coastal communities in recent years. For example, the 2011 Great East Japan Earthquake and resulting Tohoku Tsunami destroyed infrastructure along the east coast of Japan including bridge superstructures. Recent hurricanes have also caused...

  • Introducing the Concept of Foundational Attributes and Project Metabolism to Assess Construction Project Similarity

    Creator:
    Zhang, Fan
    Abstract:
    A construction project is considered to be unique due to the process of delivering a customer-designed product, diverse stakeholders involved, the unique location and timeframe of construction, and specific social, economic, and environmental constraints attached to it. The uniqueness of construction projects brought great challenges to the construction industry professionals...
