aide ff n m jze a a ary and identity by block number) 



A documented (FORTRAN IV) computer program is discussed as originally 

 written for the CERC Longshore Sand Transport Research Program to analyze wave 

 data collected at Channel Islands Harbor, California. 



The program performs the basic analysis of two wave gage pressure records 

 necessary to compute wave direction and wave energy at a given frequency and
