The results of the study are expected to solve the difficulty of getting a big size crushed stone as a required based on Hudson method. Laboratory physical model study under 1:20 geometric scale was performed. The results showed that the initial sloping breakwater was changed into the S Curve shape profile and achieve a stable condition on the profile equation of y = â��ax3 â��bx + c, where a, b and c are the factors which are functions of dHi/L2. Factor c is a relative depth (dâ��/d). The Equations obtained can be used in the planning and designing of S-Curve rubble mound breakwater with relatively small grain size of rocks. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2021. publisher: Springer Science and Business Media Deutschland GmbH date: 2021 type: Article type: PeerReviewed identifier: Thaha, M.A. and Dwipuspita, A.I. and Dharmowijoyo, D.B.E.
