20. ABSTRACT (Continue on reverse side It necessary and Identity by block number) 



Three parallel range lines were established along a straight beach at 

 Torrey Pines, California, and were surveyed at monthly intervals during June 

 1972 to May 1974. Offshore sand level changes were measured using reference 

 rods placed in the bottom at selected stations on each range line. 



Beach profile measurements indicate that the beach underwent seasonal 

 changes in configuration which are related to changes in the wave regime.
