0. ABSTRACT (Continue on reverse aide It neceaaary and identify by block number) 



An analysis of the relationship between wave and meteorological variables 

 and beach morphology was undertaken during summer and winter periods, 1971-72, 

 on Plum Island, Massachusetts. Variables were measured or computed bihourly, 

 24 hours per day, throughout both study periods. The variables were wave 

 period, wave height, breaker type, breaker angle, longshore current velocity, 

 wave steepness, breaker power, windspeed and direction, barometric pressure, 

 air and water temperature, and ground water elevation. Daily topographic maps 

 of the intertidal zone were constructed for 12 beach profiles spaced at 

 60-meter intervals. (continued)
