  • 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...

  • Setup and swash on a natural beach

    Creator:
    Sallenger, A. H., Jr. and Holman, Robert A.
    Abstract:
    Wave setup and swash statistics were calculated from 154 runup time series steep beach under incident waves varying from 0.4 to 4.0 m significant wave height. incident wave height, setup, swash height, and total runup (the sum of setup and were found to vary linearly with the surf zone similarity...

  • The influence of herbivore generated inputs on nutrient cycling and soil processes in a lower montane tropical rain forest of Puerto Rico

    Creator:
    Fonte, Steven J.
    Abstract:
    The role of insect herbivores in the nutrient cycling dynamics of forest ecosystems remains poorly understood. Although past research in herbivory has focused primarily on the deleterious effects that insects can have on tree growth and mortality, the overall effects of herbivory are more complex. Herbivores have the potential to...

  • The sediment response of a dissipative beach to variations in wave climate

    Creator:
    Haxel, Joseph H.
    Abstract:
    Using wave and wind data from nearby buoys and gauges, real time kinematic global positioning system (RTK-GPS) and light detection and ranging (lidar) topographic survey data, and a robust video record, we have quantified the Large Scale Coastal Behavior (LSCB) of a dissipative end member beach in the Pacific Northwest....

    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 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...
