Abstract

Smooth concrete slope protection structures are an interesting alternative to rip-rap slopes for areas with a mild wave climate (up to H,, = 3 m), especially where the accessibility and the aesthetic appearance of the slope is of great importance. The smooth surface makes the water line accessible to bathers and fishermen and it also enables an integrated design in the scenery. Unfortunately the smooth surface gives a much higher wave run-up, leading to a higher structure. To tackle this problem one can use a smooth surface with artificial roughness elements. The present research leads to the conclusion that relatively small roughness elements reduce wave run-up considerable, but don't effect the stability of the cover layer.
