This grant supported a variety of studies in the area of littoral processes typically as revealed by the optical remote sensing data of the Argus Program. One principle theme was me development of algorithms for estimating relevant geophysical variables such as longshore currents and wave directional spectra from ground-based optical cameras. The second theme was the study of observed nearshore physics. Much of the latter work focused on the morpho-dynamics of nearshore sand bars or foreshore morphological features. Like many nearshore phenomena, the dynamics of nearshore sand bars is dominated by strong feedbacks, with bars both causing and being caused by wave breaking. Weaknesses in our ability to characterize and understand such feedback systems are the single largest limitation in our current predictive capabilities.
