Monthly breaker height, Hb; and wave period, T. averages for wave heights and periods were concurrently measured, with a reported representative grain size. wave height and period are given by HL, and TL, respectively; similarly, storm season A single year of monthly wave data variables are given by Hs, and Ts. Wave were collected (Aguilar-Tunan and Komar, heights and periods were selected to 1978) at Gleneden Beach, Oregon, from represent conditions for the lead flanks of which a seasonal shoreline shift of about 47 seasonal accretion/recession trends, since it meters is evident. Because wave data is under these force element conditions that reported by the authors are probably responses are produced. inappropriate (i.e., they strongly appear to represent the initial offshore breaking wave Similar analyses were conducted for height), the multi-year data reported by the Boca Raton and Hollywood Beaches in U. S. Army (1984) are used. A single swash Florida (DeWall, 1977; DeWall and Richter, zone sediment size was reported by Aguilar- 1977) for four years of monthly data for V, Tunan and Komar (1978).
