The Parsian port, located in southern Iran, features a basin protected by breakwaters that extend to a seabed level of -31 m C.D. In the context of structures situated in deep waters, the toe berm emerges as the optimal choice for breakwater toe layout. Performing experimental investigations utilizing the physical breakwater model become imperative in ensuring the stability of the toe layer in wave breaking affected zone. This paper presents the outcomes of a stability analysis conducted for the Parsian port breakwater in Hydraulic Laboratory at Tarbiat Modares University. Here, various concrete units, including accropodes, cubes, and blocks, were employed to satisfy the stability criteria. The results demonstrate that using concrete units with holes in conjunction with placing a sacrificial rock layer in front of units (main toe layer) is the most effective approach for mitigating destabilizing pressure in comparison to the alternative methods as employing units with higher tonnage.
