Rock slopes and gravel beaches under wave attack

Rock slopes and gravel beaches under wave attack The stability of slopes consisring of loose materials under wave attack have been investigated with the aid of small and large scale physical models. These slopes can be divided into rubble mound breakwaters, rubble mound revetments, rock beaches and gravel or shingle beaches. The structures may be treated as either statically or dynamically stable. No displacement of material or only very little is allowed for statically stabie structures. Displacement of stanes is called daaage. Dynamically stable structures are characterized by the forming of a profile under wave attack. In this case is nat important, but the developed profile. This study describes the range from no damage to statically stable structures up to the profile development of very small (4 mm) shingle under prototype circumstan-
