  • An Agent-based Evacuation Modeling of Underground Fire Emergency

    Creator:
    Xu, Yue
    Abstract:
    Increasingly congested surface transportation network in urban areas and grow-ing land values make underground transportation systems more attractive for high-ways (i.e., tunnels) and metro system compared to other options [1]. An underground transportation system can preserve the land above for recreational parks, commer-cial buildings, residential homes, or other purposes while...

  • Networked Multi-agent Modeling of Connected Vehicles in Mixed Traffic Environment: A Decentralized Consensus Approach

    Creator:
    Wahid, Merih
    Abstract:
    Transportation systems are facing safety and operational challenges with a cost of billions of dollars annually in lost production time and wasted fuel. Infrastructure expansion, previously held as a panacea to most transportation challenges has lost its appeal due to financial, land-use and environmental constraints. Interest is surging in intelligent...

  • Coupled wave and surge modeling of Tillamook Bay, Oregon : extreme events and climate change impacts

    Creator:
    Cheng, Tiffany Kay
    Abstract:
    Estuaries represent the confluence of land and ocean environments and encompass a number of complex interactions amongst tides, winds, offshore waves and the riverine contributions, all of which contribute to total water levels (TWLs). The study of TWLs and the relative weight of its components can assist local communities in...

  • Climate Change Impacts to Estuarine Hydrodynamics: Tools, Methodologies, and Predictions

    Creator:
    Parker, Kai A.
    Abstract:
    Coastal communities in the U.S. Pacific Northwest (PNW) are rapidly engaging with the idea that hazards and environmental pressures are changing and may be characteristically different in the near future. This has led to a need for scientific knowledge and tools that can help coastal communities prepare and build resilience...

  • 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...

  • Sound and Vibration Analysis of Alternative Rumble Strips

    Creator:
    Horne, Dylan Ross
    Abstract:
    Roadway departure crashes accounted for 18,275 fatal crashes in 2017 across the United States (Jones et al. 2017). Rumble strips (RS) provide audible and haptic interior alert when a vehicle is departing the roadway reducing run-off-the road crashes. Although inexpensive to install, and easy to maintain, RS are not installed...

  • Wave Resource Assessments: Spacio-Temporal Effect of Wave Energy Converter Scale and Blue Economy Opportunities

    Creator:
    Dunkle, Gabrielle R.
    Abstract:
    Wave energy has the potential to power large and small factions of economies around the world alike. Current methods for determining the amount of wave energy resource available to wave energy converter (WEC) devices entail capturing the look of the sea state at large by presenting characteristic wave heights, periods,...

  • The Application of Machine Learning Techniques on Marine Science Models

    Creator:
    Ellenson, Ashley
    Abstract:
    A variety of stakeholders require information about marine systems. In the open ocean, pilots of marine vessels require knowledge about environmental conditions for safe passage and route planning. On the coastline, communities rely on information about nearshore dynamics to increase safety from coastal hazards such as nearshore pollutants, coastal erosion,...

  • On the nearshore impact of wave energy converter arrays

    Creator:
    O'Dea, Annika Magnuson
    Abstract:
    Radiation stresses, defined as the excess flow of momentum due to the presence of waves (Longuet-Higgins, 1964), are the main drivers behind the cross-shore and longshore forcing that results in wave setup, set-down, and longshore currents (e.g. Svendsen, 2006). Longshore currents entrain and transport sediment and therefore play an important...

  • 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...
