  • 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...

  • Pore Water Pressure Response in Soil During Tsunami Loading : Numerical Formulation and Experimentation

    Creator:
    Abdollahi, Abbas
    Abstract:
    Tsunami loading can cause sediment instability, which can compromise the structural integrity of coastal buildings and infrastructure. To understand the process by which a tsunami can cause sediment instability, it is necessary to understand how the pore water pressure in the soil changes during tsunami loading. Tsunami run-up causes the...

  • Numerical Investigations on Sewer Geysers

    Creator:
    Choi, YunJi
    Abstract:
    A sewer geyser is a series of ejecting air-water mixture eruptions through vertical shafts of drainage systems. In field observed geyser incidents, manhole covers were blown into the air and they were followed by ejecting air-water mixture eruptions that lasted for several seconds at a time. Trapped air in sewer...

  • 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...

  • A novel framework for uncertainty propagation in river systems based on performance graphs using two-dimensional hydrodynamic modeling

    Creator:
    Gifford-Miears, Christopher H.
    Abstract:
    This thesis presents a novel approach for propagation of uncertainty in river systems. Errors in data observations and predictions (e.g., stream inflows), in model parameters, and resulting from the discretization of continuous systems, all point to the need to accurately quantify the amount of uncertainty carried through the modeling process....

  • 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...

  • Hydrodynamic contact/impact modeling and application to ocean engineering problems

    Creator:
    Challa, Ravi
    Abstract:
    Fluid-structure interaction (FSI) is a very interesting and challenging multi-disciplinary field involving interaction of a movable or deformable structure with an internal or surrounding fluid flow. FSI has several practical engineering applications such as the determination of the hydrodynamic forces on a structure or the dynamics of motion of bodies...

  • 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...

  • 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...

  • Microwave scattering from surf zone waves

    Creator:
    Catalán Mondaca, Patricio A.
    Abstract:
    Wave breaking in the surf zone is an important forcing mechanism on the generation of nearshore currents and in the driving of sediment transport. At the same time, wave breaking can have significant spatial and temporal variability that needs to be accounted for in the description of nearshore processes. Remote...
