Before revision: It is important to note that when measuring the discharge over a rock revetment at the inner side of the crest , the overtopping is significantly less, assuming the recommended crest width of approximately 3 rocks in width.
After revision: The formulas above describe the wave overtopping occurring at the sea-side edge of the crest , the overtopping is significantly less, assuming the recommended crest width of approximately 3 rocks in width.
