Protection of Shoreline by Using Partial Revetment Structure under Regular and Irregular Waves

Abstract

Abstract In this paper, results obtained from an experimental investigation conducted to determine wave-induced geometric characteristics of shorelines protected by partial revetment structure are presented. The experiments were performed with both regular and irregular waves. The beach sand used in this study had a mean diameter of 0.35 millimeter and a specific gravity of 2.63. The beach had an initial slope of 1 : 5 and was protected by the partial revetment structure. For this purpose, the armor units, mean diameters and specific gravities of which were varied in the range 8.5–67.95 millimeters and 1.81–2.77, respectively, were placed on the wave-breaking area. Different wave groups were generated over an initially flat, partially protected beach, and a number of geometric characteristics of equilibrium beach profiles was determined. Moreover, the static damage of the armor layer was obtained for all test groups. The results of this experimental study were evaluated, and empirical expressions based on...
