procedure was found to be an important tool for predicting the amount of trans- 

 mission through permeable breakwaters. Suggested procedures for estimating 

 transmission coefficients have been incorporated into the computer programs OVER 

 and MADSEN (included as appendixes) and these programs may be used to predict 

 wave transmission coefficients for nonbreaking, breaking, monochromatic, and 

 irregular wave conditionsi
