OVERTOPPING ON RUBBLE MOUND BREAKWATERS FOR LOW STEEPNESS WAVES IN DEEP AND DEPTH LIMITED CONDITIONS

In this paper, the investigation of overtopping on rubble mound breakwaters for low steepness waves in both deep and shallow-water conditions are presented. The existing formulae provide quite different results for long waves for both conventional and berm breakwaters. Therefore, new model tests with focus on long waves have been performed for both types of breakwaters. The new model tests showed some deviation from the formulae. Therefore, limitations in the use of the present methods and an update for one of the methods are presented.
