!0 ABSTRACT (Continue on reverse side If necessary 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 for use with 

 HP41CV hand-held calculators which employ the Reverse Polish Notation (RPN) . 

 These programs can be used to compute linear wave parameters, orbital veloci- 

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

 limited breaking wave height, and wave transmission past a vertical barrier.
