20. ABSTRACT (Continue an rsveraa aide It neceaeary and Identity by block number) 



This report provides algorithms for a number of calculator programs useful 

 in performing coastal engineering calculations, primarily in the area of wave 

 transformations and wave generation. Six programs are included with different 

 versions for use with hand-held calculators which employ either the Reverse 

 Polish Notation (RPN) or the Algebraic Operating System (AOS) . These programs 

 can be used to compute linear wave parameters, orbital velocities, breaking 

 wave height and direction, shallow-water wave forecasts, depth-limited breaking 

 wave height, and wave transmission past a vertical barrier.
