Abstract:

Monochromatic and irregular wave transmission and reflection measurements were made for various subaerial and submerged breakwater cross sections. These two-dimensional laboratory tests included smooth impermeable breakwaters, rubble-mound breakwaters, and breakwaters armored with dolos unit. Wave transmission by overtopping was found to be related to breakwater freeboard wave runup, and breakwater crest width a method of estimating transmission by overtopping coefficients is presented. The Madsen and White 1976 numerical procedure was found to be an important tool for predicting the amount of transmission 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 conditions.
