Program 101 is another basic. program which computes not only wavelength 

 but also a number of other linear wave theory parameters. This program forms 

 the basis for program 102 and can be adapted to other programs as well. 



Program 102 computes linear wave parameters and breaking wave height and 

 direction based on nearshore or deepwater wave information. Program 103 can 

 be used to forecast wave height and period in shallow water. Program 104 and 

 105 address wave conditions at structures — program 104 predicts the depth- 

 limited design breaking wave height at a structure; 105 uses Fuch's equation 

 to predict wave transmission over a thin barrier. 



Each program allows either English or metric input and output (the AGS 

 programs print an "M" when metric is selected) . Program listings are anno- 

 tated, making it possible to follow the logic of the algorithm and to make 

 modifications if desired. 



There are undoubtedly many calculator programs not included here that have 

 been developed on coastal engineering subjects. Practicing engineers who would 

 like to disseminate such programs (in either AGS or RPN) to other users are 

 encouraged to submit them to the Coastal Engineering Research Center (CERC) . 

 If the response is great enough, additional reports presenting the programs 

 will be prepared. Comments, programs, or suggestions for programs should be 

 sent to :

These programs and future programs will generally correspond to the following 

 number ing scheme : 



Miscellaneous 0-99 



Waves and currents 100-299 



Inlets 300-499 



Beaches 500-699 



Geology 700-899 



Structures 900-1099 



In general, the documentation of programs submitted should be in a format 

 paralleling that of the programs presented in this report. A blank set of 

 forms which can be reproduced is included in the Appendix.
