Discussion/comments of “Drag coefficient prediction model for simulating breaking waves propagating on partly submerged vegetated sloping beaches using a RANS model” by Yanxu Wang, Quanlin Qiu, Zegao Yin, Xiutao Jiang and Xuan Zang

The purpose of these comments and discussion has been to point out how wave statistics can be incorporated in applications of the drag coefficient model for regular breaking waves propagating on partly submerged vegetated sloping beaches proposed by Wang et al. (2025). This is demonstrated by using a distribution of the surf parameter provided by Myrhaug and Fouques (2007). Examples of results are given by applying a Phillips wave amplitude spectrum for wind sea.
