Experimental Study of Grading Effect On Stability of S - Shape Breakwaters

- This paper studies the grading effect on stability of S - shape breakwaters. A series of hydraulic model tests has been carried out on models of berm breakwater. In these tests mean nominal size of armour units (Dnso) has been kept constant, how ever different grading, i.e.. different ratios of Dgs/Du have been used. Tests have been performed for the first 1000 and also for the subsequent 1000 incident waves. The results have been presented in the form of deformed shape of breakwater and have been discussed on the basis of non-dimensional parameters.
