3. Program Variables . A description of all program variables is presented 

 in Table F-1. 



4. Input . A description and an example of the imput parameters are given 

 in Table F-2. Note that all measurements are in metric linits. 



5. Output . Program output includes a summary table of input information 

 together with the predicted ratio of the breakwater freeboard to wave runup, 

 the wave transmission by overtopping coefficient, and the predicted transmitted 

 wave height. An example output corresponding to the input is shown in Table F-3. 



6. Program Listing . A listing of the program is shown in Table F-4. The 

 subroutine LENGTH finds the value of d/L given d/L^-, by using linear wave 

 theory.
