Abstract:

The purpose of the field study described in this report was to determine the characteristic summer equilibrium profile form and composition of the Atlantic Ocean beach of Sandy Hook, New Jersey, and to determine in detail the minor cyclic fluctuations in profile and sediment composition imposed by the semidiurnal tidal cycle. To conduct the required instrumental field surveys, reference grids were laid out on the beach at two field stations to provide horizontal and vertical control for profile lines surveyed transverse to the shoreline in the foreshore zone. Surveys carried out during the summers of 1959, 1960, and 1961 provided data on the characteristic form and evolution of the beach during the summer regime of low waves and persistent obliquity of wave approach from the southeast. A series of half-hourly profile surveys permitted documentation of the small changes of beach form accompanying the rise and fall of tide and led to the formulation of a schematic model for the sequences of erosion and deposition in a semidiurnal tidal cycle.
