The breakwater as structures that have an important role in the protection of coastal facilities was used to create calm in the harbor, reduce wave energy and also protect the coast against wave attack. Wave overtopping is an important parameter to design breakwater. In this paper, a new formula will be proposed to estimate wave overtopping on the reshaping breakwater. In this research, further effective parameters such as stone diameter (Dn50) and water depth at toe of the structure (d) were considered to estimate wave overtopping. Wave overtopping occurs when water level goes higher than the crest of the structure. To derive a new formula, at first a relation was proposed using hydraulic and structural parameters associated with wave overtopping and then the dimensionless parameter was used by Buckingham theory. A comparison was made between the new relation and the relations proposed by former studies. This research indicated that the proposed formula is accurate in estimating wave overtopping on reshaping berm breakwater.
