Experiments were conducted in a 2D monochromatic wave flume to study the minimum (critical) weight required to resist the sliding of emerged seaside perforated quarter circle breakwater models with radius 0.55 m and ratio of spacing to diameter of perforations (S/D) equal to 2, 2.5, 3, 4 and 5. From the results it was observed that the non -dimensional stability parameter (W/gamma/H-i(2)?) is always decreasing with the increase in wave steepness, H-i/gT(2), but increasing with increase in ratio of water depth to height of the breakwater structure or relative water depth (d/h(s)) and S/D. Minimum W/gamma H-i(2), was observed corresponding to S/D=2.5 and d/h(s) = 0.569.Article
