  • Wave runup : Physics, variability, and societal impacts

    Creator:
    García Medina, Gabriel
    Abstract:
    The U.S. Pacific Northwest is home to one of the most extreme wave climates in the world with waves of 10 m in height arriving to the coast approximately each year. With an average water temperature of 12℃, the beaches in the region are too cold to go on a...

  • Observations of cross-shore sediment transport and formulation of the undertow

    Creator:
    Guannel, Gregory E.
    Abstract:
    A new set of data from a large-scale sand bar migration experiment is presented. During this experiment, two sandbars were generated. One of the bar was generated by the action of undertow, and sediment moved offshore. The other bar was generated by the shoreward movement of sediment coming from the...

  • Offshore controls on nearshore circulation

    Creator:
    Long, Joseph W.
    Abstract:
    The rip current field resulting from the transformation of surface gravity waves over offshore submarine canyons is studied. Employing a wave transformation model and a wave-induced circulation model over observed bathymetry we find that rip current circulation cells exist with alongshore spacing of O(1OOm) even though the nearshore bathymetry displayed...

  • Nearshore wave predictions along the Oregon and southwest Washington coast

    Creator:
    García-Medina, Gabriel
    Abstract:
    This thesis contains a manuscript describing the implementation of a high resolution wave forecasting model for the coasts of Washington and Oregon. The purpose of this project was to advance the wave predictive capabilities of the states of Oregon and the southwest part of Washington by including the effects of...

  • Nearshore hydrodynamic model comparisons and predictions of bathymetric evolution

    Creator:
    Lescinski, Jamie M.
    Abstract:
    The surf zone exhibits large energetic signals from wave shoaling and subsequent dissipation due to breaking, forcing circulation. The bathymetry responds to the wave and wave-induced circulation with the growth, transport, and destruction of large scale bathymetric features, such as mega ripples and sand bars. There is an obvious fluctuation...
