computes the longshore energy flux used in sand transport for the entire 

 energy spectrum of the wave record. This program uses linear wave theory for 

 the wave transformation process and includes the assumption of straight and 

 parallel bottom contours necessary for application of Snell's law of 

 refraction. 



The necessary steps in an analysis of wave data and sample outputs for 

 some wave records from the Channel Islands wave gage pressure sensor pair are 

 given. The program presently accepts data in the standard CERC magnetic-tape 

 format where record lengths consist of 4,100 values.
