specified maximum, and the crest is increased 1 ft for another round of trans- 

 mission computations if the condition is not satisfied. The computations ap- 

 ply to Equations 26-29 and the armor unit data from Table 5 in the main text. 



Sample Interactive Session 



10. Below is a sample interactive session for program "BWCOMP" (FORTRAN 

 version) . 



BWCOMP IS AN INTERACTIVE PROGRAM WHICH COMPUTES BREAKWATER 

 VOLUMES AND COSTS FOR A SIMPLE PARAMETERIZED CROSS SECTION FOR 

 THE PURPOSE OF COMPARING THE EFFECT OF CHANGING THE SEAWARD 

 AND LEEWARD SLOPES ON THE SIZE AND RELATIVE COST OF A RANGE OF 

 ARMOR UNIT TYPES. THE OUTPUT OF BWCOMP SHOULD NOT BE USED 

 AS A COST ESTIMATING TOOL IN ANY STAGE OF A PLANNING OR DESIGN 

 PROJECT. THE ASSUMPTIONS APPLIED ARE INTENDED TO TENTATIVELY 

 IDENTIFY THE OPTIMUM COMBINATION OF SLOPES AND ARMOR UNIT 

 FOR A GIVEN SET OF DESIGN CRITERIA.
