"This report presents the results of a study of the reflection and transmission characteristics of porous rubble-mound breakwaters. An attempt was made at making the procedures entirely self-contained by introducing empirical relationships for the hydraulic characteristics of the porous material and by establishing experimentally an empirical relationship for the friction factor that expresses energy dissipation on the seaward slope of a breakwater.
