Rock slopes and gravel beaches under wave attack

TLDR

Slopes composed of loose materials are classified as rubble mound breakwaters, rubble mound revetments, rock beaches, or gravel/shingle beaches. The study aims to characterize the continuum from no damage to statically stable slopes up to the development of a wave‑formed profile in very small (4 mm) shingle. Using small and large‑scale physical models, the authors examined stability of loose‑material slopes, treating them as either statically stable—allowing only minimal displacement—or dynamically stable, where a wave‑generated profile forms. Displacement of stones is defined as damage.

Abstract

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-
