  • 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....

  • 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...

  • Remote sensing of radiation stress gradients from optical imagery

    Creator:
    Killian, Jason R.
    Abstract:
    Wave-induced circulation is the defining characteristic of the nearshore. Within this region, the constant feedback cycle between incoming waves, wave-generated currents, and the mobile sediment bed is responsible for the evolution of complex patterns in nearshore and beach morphology. Central to our understanding of this system is knowledge of the...

  • Analysis of rip current embayments on the Oregon coast

    Creator:
    Dalon, Matthew M.
    Abstract:
    Understanding the past, present, and future behavior of our nation's shorelines is vital for sensible coastal management. Localized areas of erosion, termed "erosional hot spots", can shift the shoreline landward threatening coastal infrastructure (Kraus and Galgano, 2001; Stauble and Gravens, 2004; McNinch, 2004). One specific type of erosional hot spot...

  • Remote measurements of waves and currents over complex bathymetry

    Creator:
    Chickadel, Carmine C. (Carmine Christopher)
    Abstract:
    Waves are the primary input of energy in the nearshore region, and together with the currents forced through the transfer of momentum that occurs during the wave breaking process they are the principal mechanism for sediment transport in the nearshore. The basic physics of waves and currents are thought to...

  • Predicting the longshore-variable coastal response to hurricanes

    Creator:
    Stockdon, Hilary F.
    Abstract:
    The longshore variability of the coastal response to hurricanes may be examined within the framework of a storm-impact scaling model that compares spatially-variable beach morphology and fluid forcing. The relative elevations of dune height and storm-induced water levels are used to define three impact regimes (swash, collision, and overwash), within...

  • Development of 2D models to estimate nearshore bathymetry and sediment transport

    Creator:
    Splinter, Kristen D.
    Abstract:
    We examine the interactions and feedbacks between bathymetry, waves, currents, and sediment transport. The first two pro jects focus on the use of remote sensing techniques to expand our knowledge of the nearshore. Due to the plethora of snap-shot data that is available from satellites and their distribution via Google...

  • Laboratory observations and numerical modeling of inner surf and swash zone hydrodynamics on a steep slope

    Creator:
    Shin, Sungwon
    Abstract:
    Laboratory data of free surface elevations and fluid velocities were obtained using a laser-Doppler velocimeter for the case of a periodic wave plunging over an impermeable, steep (1:10) slope with a fixed bottom roughness. The measurements were conducted over 15 cross-shore locations from the outer surf zone to the swash...
