Update to Friction Factor Formulations That Impact Rocky Shores and Coral Reefs

Abstract The bottom friction factor, , estimates for computing wave bottom frictional dissipation in Gon et al. (2020, https://doi.org/10.1029/2019jc015963 ), titled Wave Dissipation by Bottom Friction on the Inner Shelf of a Rocky Shore , are too large by a factor of 2 due to an error in the formulations by Thornton and Guza (1983, https://doi.org/10.1029/jc088ic10p05925 ), titled Transformation of Wave Height Distribution . Corrected formulations reduce the prior overestimation of the bottom friction coefficient, , which is more significant for rougher bottom surfaces, such as coral reefs and rocky shores, than for sandy beaches.
