  • Estimating nearshore bedform amplitudes with altimeters 

    Gallagher, E. L.; Elgar, Steve; Guza, R. T.; Thornton, Ed B. (2005-01-14)
    Estimates of the heights of large (0.1-0.4 m heights and 1-10 m horizontal lengths) migrating bedforms on a sandy beach made with fixed, single-point altimeters are similar to heights estimated from profiles across the ...
  • Microwave radar cross sections and Doppler velocities measured in the surf zone 

    Farquharson, Gordon; Frasier, Stephen J.; Raubenheimer, Britt; Elgar, Steve (American Geophysical Union, 2005-12-23)
    The relationship between microwave imaging radar measurements of fluid velocities in the surf zone and shoaling, breaking, and broken waves is studied with field observations. Normalized radar cross section (NRCS) and ...
  • Nonlinear generation and loss of infragravity wave energy 

    Henderson, Stephen M.; Guza, R. T.; Elgar, Steve; Herbers, T. H. C.; Bowen, A. J. (American Geophysical Union, 2006-12-08)
    Nonlinear energy transfers with sea and swell (frequencies 0.05–0.40 Hz) were responsible for much of the generation and loss of infragravity wave energy (frequencies 0.005–0.050 Hz) observed under moderate- and low-energy ...
  • The role of morphology and wave-current interaction at tidal inlets : an idealized modeling analysis 

    Olabarrieta, Maitane; Geyer, W. Rockwell; Kumar, Nirnimesh (John Wiley & Sons, 2014-12-23)
    The outflowing currents from tidal inlets are influenced both by the morphology of the ebb-tide shoal and interaction with incident surface gravity waves. Likewise, the propagation and breaking of incident waves are affected ...
  • Testing and calibrating parametric wave transformation models on natural beaches 

    Apotsos, Alex; Raubenheimer, Britt; Elgar, Steve; Guza, R. T. (2007-10-04)
    To provide coastal engineers and scientists with a detailed inter-comparison of widely used parametric wave transformation models, several models are tested and calibrated with extensive observations from 6 field experiments ...
  • Turbulence in the shallow nearshore environment during SANDYDUCK '97 

    Fredericks, Janet J.; Trowbridge, John H.; Voulgaris, George (Woods Hole Oceanographic Institution, 2001-02)
    An array of five acoustic Doppler velocimeters (ADV), which produce high quality measurements of the three-dimensional velocity vector in a sample volume with a scale of one centimeter, was deployed from late August through ...
  • Vorticity generation by short-crested wave breaking 

    Clark, David B.; Elgar, Steve; Raubenheimer, Britt (American Geophysical Union, 2012-12-21)
    Eddies and vortices associated with breaking waves rapidly disperse pollution, nutrients, and terrestrial material along the coast. Although theory and numerical models suggest that vorticity is generated near the ends of ...
